 Fixed typo in BLAS gemm3m call to _check().
 
 Details:
 - Fixed an unresolved symbol issue leftover from 590 whereby ?gemm3m_()
   as defined in bla_gemm3m.c was referencing bla_gemm3m_check(), which
   does not exist. It should have simply called the _check() function for
   gemm.

 AMD kernel updates; frame-specific AMD updates. (597)
 
 Details:
 - Allow building BLIS with certain framework files (each with the '_amd'
   suffix) that have been customized by AMD for Zen-based hardware. These
   customized files were derived from portable versions of the same files
   (i.e., those without the '_amd' suffix). Whether the portable or AMD-
   specific files are compiled is now controlled by a new configure
   option, --[en|dis]able-amd-frame-tweaks. This option is disabled by
   default in vanilla BLIS, though AMD may choose to enable it by default
   in their fork. For now, the added AMD-specific files are:
   - bli_gemv_unf_var2_amd.c
   - bla_copy_amd.c
   - bla_gemv_amd.c
   These files reside in 'amd' subdirectories found within the directory
   housing their generic counterparts.
 - Register optimized real-domain copyv, setv, and swapv kernels in
   bli_cntx_init_zen.c.
 - Various minor updates to level-1v kernels in 'zen' kernel set.
 - Added caxpyf kernel as well as saxpyf and multiple daxpyf kernels to
   the 'zen' kernel set
 - If the problem passed to ?gemm_() in bla_gemm.c has a unit m or n dim,
   call gemv instead and return early.
 - Combined variable declarations with their initialization in various
   level-2 and level-3 BLAS compatibility files, and also inserted
   'const' qualifer in those same declaration statements.
 - Moved frame/compat/bla_gemmt.c and .h to frame/compat/extra/ .
 - Added copyv and swapv test drivers to 'test' directory.
 - Whitespace, comment changes.

 Added BLAS/CBLAS APIs for gemm3m. (590)
 
 Details:
 - Created ?gemm3m_() and cblas_?gemm3m() APIs that (for now) simply
   invoke the 1m implementation unconditionally. (Note that these APIs
   bypass sup handling.)
 - Added BLAS prototypes for gemm3m in frame/compat/bla_gemm3m.h.
 - Added CBLAS prototypes for gemm3m in frame/compat/cblas/src/cblas.h.
 - Relocated:
     frame/compat/cblas/src/cblas_?gemmt.c
   files into
     frame/compat/cblas/src/extra/
 - Relocated frame/compat/bla_gemmt.? into frame/compat/extra/ .
 - Minor reorganization of prototypes and cpp macro directives in
   bli_blas.h, cblas.h, and cblas_f77.h.
 - Trival whitespace change to cblas_zgemm.c.

 Avoid gemmsup barriers when not packing A or B. (622)
 
 Details:
 - Implemented a multithreaded optimization for the special (and common)
   case of employing the gemmsup code path when the user requests
   (implicitly or explicitly) that neither A nor B be packed during
   computation. This optimization takes the form of a greatly reduced
   code branch in bli_thrinfo_sup_create_for_cntl(), which avoids a
   broadcast and two barriers, and results in higher performance when
   obtaining two-way or higher parallelism within BLIS. Thanks to
   Bhaskar Nallani of AMD for proposing this change via issue 605.
 - Added an early return branch to bli_thrinfo_create_for_cntl() that
   detects and quickly handles cases where no parallelism is being
   obtained within BLIS (i.e., single-threaded execution). Note that
   this special case handling was/is already present in
   bli_thrinfo_sup_create_for_cntl().
 - CREDITS file update.

 Fixed level-3 performance bug in haswell ukernels.
 
 Details:
 - Fixed a performance regression affecting nearly all level-3 operations
   that use the 'haswell' sgemm and dgemm microkernels. This regression
   was introduced in 54fa28b, caused by an ill-formed conditional
   expression in the assembly code that controls whether cache lines of C
   should be prefetched as rows or as columns. Essentially, the two
   branches were reversed, causing incomplete prefetching to occur for
   both row- and column-stored instances of matrix C. Thanks to Devin
   Matthews for his help finding and fixing this bug.

 Revamp how tools are handled/checked by configure.
 
 Details:
 - Consolidate handling of tools that are specifiable via CC, CXX, FC,
   PYTHON, AR, and RANLIB into one bash function, select_tool_w_env().
   - If the user specifies a tool via an environment variable (e.g.
     CC=gcc) and that tool does not seem valid, print an error message
     and abort configure, unless the tool is optional (e.g. CXX or FC),
     in which case a warning message is printed instead.
   - The definition of "seems valid" above amounts to:
     - responding to at least one of a basic set of command line options
       (e.g. --version, -V, -h) if the os_name is Linux (since GNU tools
       tend to respond to flags such as --version) or if the tool in
       question is CC, CXX, FC, or PYTHON (which tend to respond to the
       expected flags regardless of OS)
     - the binary merely existing for AR and RANLIB on Darwin/OSX/BSD.
       (These OSes tend to have non-GNU versions of ar and ranlib, which
       typically do not respond to --version and friends.)
 - This PR addresses 584. Thanks to Devin Matthews for suggesting some
   of the changes in this commit.

 Move edge cases to gemmtrsm ukrs; doc updates.
 
 Details:
 - Moved edge-case handling into the gemmtrsm microkernel. This required
   changing the microkernel API to take m and n dimension parameters as
   well as updating all existing gemmtrsm microkernel function pointer
   types, function signatures, and related definitions to take m and n
   dimensions. Also updated all existing gemmtrsm kernels in the
   'kernels' directory (which for now is limited to haswell and penryn
   kernel sets, plus native and 1m-based reference kernels in
   'ref_kernels') to take m and n dimensions, and implemented edge-case
   handling within those microkernels via a collection of new C
   preprocessor macros defined within bli_edge_case_macro_defs.h. Note
   that the edge-case handling for gemm-like operations had already
   been relocated into the gemm microkernel in 54fa28b.
 - Added desriptive comments to GEMM_UKR_SETUP_CT() and related macros in
   bli_edge_case_macro_defs.h to allow for easier reading.
 - Updated docs/KernelsHowTo.md to reflect above changes. Also cleaned up
   the bullet under "Implementation Notes for gemm" that covers alignment
   issues. (Thanks to Ivan Korostelev for pointing out the confusing and
   outdated language in issue 591.)
 - Other minor tweaks to KernelsHowTo.md.

 Added m, n dims to gemmd/gemmlike ukernel calls.
 
 Details:
 - Updated the gemmd addon and the gemmlike sandbox code to use the new
   microkernel calling sequence, which now includes m and n dimensions so
   that the microkernel has all the information necessary to handle edge
   cases. Thanks to Jeff Diamond for catching this, which ideally would
   have been included in commit 54fa28b.
 - Retired var2 of both gemmd and gemmlike to 'attic' directories and
   removed their corresponding prototypes. In both cases, var2 was a
   variant of the block-panel algorithm where edge-case handling was
   abstracted away to a microkernel wrapper. (Since this is now the
   official behavior of BLIS microkernels, I saw no need to have it
   included as a separate code path.)
 - Comment updates.

 Move edge cases to gemm ukr; more user-custom mods. (583)
 
 Details:
 - Moved edge-case handling into the gemm microkernel. This required
   changing the microkernel API to take m and n dimension parameters.
   This required updating all existing gemm microkernel function pointer
   types, function signatures, and related definitions to take m and n
   dimensions. We also updated all existing kernels in the 'kernels'
   directory to take m and n dimensions, and implemented edge-case
   handling within those microkernels via a collection of new C
   preprocessor macros defined within bli_edge_case_macro_defs.h. Also
   removed the assembly code that formerly would handle general stride
   IO on the microtile, since this can now be handled by the same code
   that does edge cases.
 - Pass the obj_t.ker_fn (of matrix C) into bli_gemm_cntl_create() and
   bli_trsm_cntl_create(), where this function pointer is used in lieu of
   the default macrokernel when it is non-NULL, and ignored when it is
   NULL.
 - Re-implemented macrokernel in bli_gemm_ker_var2.c to be a single
   function using byte pointers rather that one function for each
   floating-point datatype. Also, obtain the microkernel function pointer
   from the .ukr field of the params struct embedded within the obj_t
   for matrix C (assuming params is non-NULL and contains a non-NULL
   value in the .ukr field). Communicate both the gemm microkernel
   pointer to use as well as the params struct to the microkernel via
   the auxinfo_t struct.
 - Defined gemm_ker_params_t type (for the aforementioned obj_t.params
   struct) in bli_gemm_var.h.
 - Retired the separate _md macrokernel for mixed datatype computation.
   We now use the reimplemented bli_gemm_ker_var2() instead.
 - Updated gemmt macrokernels to pass m and n dimensions into microkernel
   calls.
 - Removed edge-case handling from trmm and trsm macrokernels.
 - Moved most of bli_packm_alloc() code into a new helper function,
   bli_packm_alloc_ex().
 - Fixed a typo bug in bli_gemmtrsm_u_template_noopt_mxn.c.
 - Added test/syrk_diagonal and test/tensor_contraction directories with
   associated code to test those operations.

 Enable user-customized packm ukernel/variant. (549)
 
 Details:
 - Added four new fields to obj_t: .pack_fn, .pack_params, .ker_fn, and
   .ker_params. These fields store pointers to functions and data that
   will allow the user to more flexibly create custom operations while
   recycling BLIS's existing partitioning infrastructure.
 - Updated typed API to packm variant and structure-aware kernels to
   replace the diagonal offset with panel offsets, and changed strides
   of both C and P to inc/ldim semantics. Updated object API to the packm
   variant to include rntm_t*.
 - Removed the packm variant function pointer from the packm cntl_t node
   definition since it has been replaced by the .pack_fn pointer in the
   obj_t.
 - Updated bli_packm_int() to read the new packm variant function pointer
   from the obj_t and call it instead of from the cntl_t node.
 - Moved some of the logic of bli_l3_packm.c to a new file,
   bli_packm_alloc.c.
 - Rewrote bli_packm_blk_var1.c so that it uses byte (char*) pointers
   instead of typed pointers, allowing a single function to be used
   regardless of datatype. This obviated having a separate implementation
   in bli_packm_blk_var1_md.c. Also relegated handling of scalars to a
   new function, bli_packm_scalar().
 - Employed a new standard whereby right-hand matrix operands ("B") are
   always packed as column-stored row panels -- that is, identically to
   that of left-hand matrix operands ("A"). This means that while we pack
   matrix A normally, we actually pack B in a transposed state. This
   allowed us to simplify a lot of code throughout the framework, and
   also affected some of the logic in bli_l3_packa() and _packb().
 - Simplified bli_packm_init.c in light of the new B^T convention
   described above. bli_packm_init()--which is now called from within
   bli_packm_blk_var1()--also now calls bli_packm_alloc() and returns
   a bool that indicates whether packing should be performed (or
   skipped).
 - Consolidated bli_gemm_int() and bli_trsm_int() into a bli_l3_int(),
   which, among other things, defaults the new .pack_fn field of the
   obj_t to bli_packm_blk_var1() if the field is NULL.
 - Defined a new function, bli_obj_reset_origin(), which permanently
   refocuses the view of an object so that it "forgets" any offsets from
   its original pointer. This function also sets the object's root field
   to itself. Calls to bli_obj_reset_origin() for each matrix operand
   appear in the _front() functions, after the obj_t's are aliased. This
   resetting of the underlying matrices' origins is needed in preparation
   for more advanced features from within custom packm kernels.
 - Redefined bli_pba_rntm_set_pba() from a regular function to a static
   inline function.
 - Updated gemm_ukr, gemmtrsm_ukr, and trsm_ukr testsuite modules to use
   libblis_test_pobj_create() to create local packed objects. Previously,
   these packed objects were created by calling lower-level functions.

 Added support for AMD's Zen3 microarchitecture.
 
 Details:
 - Added a new 'zen3' subconfiguration targeting support for the AMD Zen3
   microarchitecture (561). Thanks to AMD for this contribution.
 - Restructured clang and AOCC support for zen, zen2, and zen3
   make_defs.mk files. The clang and AOCC version detection now happens
   in configure, not in the subconfigurations' makefile fragments. That
   is, we've added logic to configure that detects the version of
   clang/AOCC, outputs an appropriate variable to config.mk
   (ie: CLANG_OT_*, AOCC_OT_*), and then checks for it within the
   makefile fragment (as is currently done for the GCC_OT_* variables).
 - Added configure support for a GCC_OT_10_1_0 variable (and associated
   substitution anchor) to communicate whether the gcc version is older
   than 10.1.0, and use this variable to check for recent enough versions
   of gcc to use -march=znver3 in the zen3 subconfig.
 - Inlined the contents of config/zen/amd_config.mk into the zen and zen2
   make_defs.mk so that the files are self-contained, harmonizing the
   format of all three Zen-based subconfigurations' make_defs.mk files.
 - Added indenting (with spaces) of GNU make conditionals for easier
   reading in zen, zen2, and zen3 make_defs.mk files.
 - Adjusted the range of models checked by bli_cpuid_is_zen() (which was
   previously 0x00 ~ 0xff and is now 0x00 ~ 0x2f) so that it is
   completely disjoint from the models checked by bli_cpuid_is_zen2()
   (0x30 ~ 0xff). This is normally necessary because Zen and Zen2
   microarchitectures share the same family (23, or 0x17), and so the
   model code is the only way to differentiate the two. But in our case,
   fixing the model range for zen *wasn't* actually necessary since we
   checked for zen2 first, and therefore the wide zen range acted like
   the 'else' of an 'if-else' statement. That said, the change helps
   improve clarity for the reader by encoding useful knowledge, which
   was obtained from https://en.wikichip.org/wiki/amd/cpuid .
 - Added zen2.def and zen3.def files to the collection in travis/cpuid.
   Note that support for zen, zen2, and zen3 is now present, and while
   all the three microarchitectures have identical instruction sets from
   the perspective of BLIS microkernels, they each correspond to
   different subconfigurations and therefore merit separate testing.
   Thanks to Devin Matthews for his guidance in hacking these files as
   slight modifications of zen.def.
 - Enabled testing of zen2 and zen3 via the SDE in travis/do_sde.sh.
   Now, zen, zen2, and zen3 are tested through the SDE via Travis CI
   builds.
 - Updated travis/do_sde.sh to grab the SDE tarball from a new ci-utils
   repository on GitHub rather than on Intel's website. This change was
   made in an attempt to circumvent recent troubles with Travis CI not
   being able to download the SDE directly from Intel's website via curl.
   Thanks to Devin Matthews for suggesting the idea.
 - Updated travis/do_sde.sh to grab the latest version (8.69.1) of the
   Intel SDE from the flame/ci-utils repository.
 - Updated .travis.yml to use gcc 9. The file was previously using gcc 8,
   which did not support -march=znver2.
 - Created amd64_legacy umbrella family in config_registry for targeting
   older (bulldozer, piledriver, steamroller, and excavator)
   microarchitectures and moved those same subconfigs out of the amd64
   umbrella family. However, x86_64 retains amd64_legacy as a constituent
   member.
 - Fixed a bug in configure related to the building of the so-called
   config list. When processing the contents of config_registry,
   configure creates a series of structures and lists that allow for
   various mappings related to configuration families, subconfigs, and
   kernel sets. Two of those lists are built via substitution of
   umbrella families with their subconfig members, and one of those
   lists was improperly performing the substitution in a way that would
   erroneously match on partial umbrella family names. That code was
   changed to match the code that was already doing the substitution
   properly, via substitute_words(). Also added comments noting the
   importance of using substitute_words() in both instances.
 - Comment updates.

 Added support for addons.
 
 Details:
 - Implemented a new feature called addons, which are similar to
   sandboxes except that there is no requirement to define gemm or any
   other particular operation.
 - Updated configure to accept --enable-addon=<name> or -a <name> syntax
   for requesting an addon be included within a BLIS build. configure now
   outputs the list of enabled addons into config.mk. It also outputs the
   corresponding include directives for the addons' headers to a new
   companion to the bli_config.h header file named bli_addon.h. Because
   addons may wish to make use of existing BLIS types within their own
   definitions, the addons' headers must be included sometime after that
   of bli_config.h (which currently is included before bli_type_defs.h).
   This is why the include directives needed to go into a new top-level
   header file rather than the existing bli_config.h file.
 - Added a markdown document, docs/Addons.md, to explain addons, how to
   build with them, and what assumptions their authors should keep in
   mind as they create them.
 - Added a gemmlike-like implementation of sandwich gemm called 'gemmd'
   as an addon in addon/gemmd. The code uses a 'bao_' prefix for local
   functions, including the user-level object and typed APIs.
 - Updated .gitignore so that git ignores bli_addon.h files.

 Added BLAS/CBLAS APIs for axpby, gemm_batch. (566)
 
 Details:
 - Expanded the BLAS compatibility layer to include support for
   ?axpby_() and ?gemm_batch_(). The former is a straightforward
   BLAS-like interface into the axpbyv operation while the latter
   implements a batched gemm via loops over bli_?gemm(). Also
   expanded the CBLAS compatibility layer to include support for
   cblas_?axpby() and cblas_?gemm_batch(), which serve as wrappers to
   the corresponding (new) BLAS-like APIs. Thanks to Meghana Vankadari
   for submitting these new APIs via 566.
 - Fixed a long-standing bug in common.mk that for some reason never
   manifested until now. Previously, CBLAS source files were compiled
   *without* the location of cblas.h being specified via a -I flag.
   I'm not sure why this worked, but it may be due to the fact that
   the cblas.h file resided in the same directory as all of the CBLAS
   source, and perhaps compilers implicitly add a -I flag for the
   directory that corresponds to the location of the source file being
   compiled. This bug only showed up because some CBLAS-like source code
   was moved into an 'extra' subdirectory of that frame/compat/cblas/src
   directory. After moving the code, compilation for those files failed
   (because the cblas.h header file, presumably, could not be found in
   the same location). This bug was fixed within common.mk by explicitly
   adding the cblas.h directory to the list of -I flags passed to the
   compiler.
 - Added test_axpbyv.c and test_gemm_batch.c files to 'test' directory,
   and updated test/Makefile to build those drivers.
 - Fixed typo in error message string in cblas_sgemm.c.

 Refactored her[2]k/syr[2]k in terms of gemmt. (531)
 
 Details:
 - Renamed herk macrokernels and supporting files and functions to gemmt,
   which is possible since at the macrokernel level they are identical.
   Then recast herk/her2k/syrk/syr2k in terms of gemmt within the expert
   level-3 oapi (bli_l3_oapi_ex.c) while also redefining them as literal
   functions rather than cpp macros that instantiate multiple functions.
   Thanks to Devin Matthews for his efforts on this issue (531).
 - Check that the maximum stack buffer size is sufficiently large
   relative to the register blocksizes for each datatype, and do so when
   the context is initialized rather than when an operation is called.
   Note that with this change, users who pass in their own contexts into
   the expert interfaces currently will *not* have any checks performed.
   Thanks to Devin Matthews for suggesting this change.

 Fixed bug in mixed-dt gemm introduced in e9da642.
 
 Details:
 - Fixed a bug that broke certain mixed-datatype gemm behavior. This
   bug was introduced recently in e9da642 when the code that performs
   the operation transposition (for microkernel IO preference purposes)
   was moved up so that it occurred sooner. However, when I moved that
   code, I failed to notice that there was a cpp-protected "if"
   conditional that applied to the entire code block that was moved. Once
   the code block was relocated, the orphaned if-statement was now
   (erroneously) glomming on to the next thing that happened to be in the
   function, which happened to be the call to bli_rntm_set_ways_for_op(),
   causing a rather odd memory exhaustion error in the sba due to the
   num_threads field of the rntm_t still being -1 (because the rntm_t
   field were never processed as they should have been). Thanks to
   ArcadioN09 (Snehith) for reporting this error and helpfully including
   relevant memory trace output.

 Removed support for 3m, 4m induced methods.
 
 Details:
 - Removed support for all induced methods except for 1m. This included
   removing code related to 3mh, 3m1, 4mh, 4m1a, and 4m1b as well as any
   code that existed only to support those implementations. These
   implementations were rarely used and posed code maintenance challenges
   for BLIS's maintainers going forward.
 - Removed reference kernels for packm that pack 3m and 4m micropanels,
   and removed 3m/4m-related code from bli_cntx_ref.c.
 - Removed support for 3m/4m from the code in frame/ind, then reorganized
   and streamlined the remaining code in that directory. The *ind(),
   *nat(), and *1m() APIs were all removed. (These additional API layers
   no longer made as much sense with only one induced method (1m) being
   supported.) The bli_ind.c file (and header) were moved to frame/base
   and bli_l3_ind.c (and header) and bli_l3_ind_tapi.h were moved to
   frame/3.
 - Removed 3m/4m support from the code in frame/1m/packm.
 - Removed 3m/4m support from trmm/trsm macrokernels and simplified some
   pointer arithmetic that was previously expressed in terms of the
   bli_ptr_inc_by_frac() static inline function (whose definition was
   also removed).
 - Removed the following subdirectories of level-0 macro headers from
   frame/include/level0: ri3, rih, ri, ro, rpi. The level-0 scalar macros
   defined in these directories were used exclusively for 3m and 4m
   method codes.
 - Simplified bli_cntx_set_blkszs() and bli_cntx_set_ind_blkszs() in
   light of 1m being the only induced method left within BLIS.
 - Removed dt_on_output field within auxinfo_t and its associated
   accessor functions.
 - Re-indexed the 1e/1r pack schemas after removing those associated with
   variants of the 3m and 4m methods. This leaves two bits unused within
   the pack format portion of the schema bitfield. (See bli_type_defs.h
   for more info.)
 - Spun off the basic and expert interfaces to the object and typed APIs
   into separate files: bli_l3_oapi.c and bli_l3_oapi_ex.c; bli_l3_tapi.c
   and bli_l3_tapi_ex.c.
 - Moved the level-3 operation-specific _check function calls from the
   operations' _front() functions to the corresponding _ex() function of
   the object API. (This change roughly maintains where the _check()
   functions are called in the call stack but lays the groundwork for
   future changes that may come to the level-3 object APIs.) Minor
   modifications to bli_l3_check.c to allow the check() functions to be
   called from the expert interface APIs.
 - Removed support within the testsuite for testing the aforementioned
   induced methods, and updated the standalone test drivers in the 'test'
   directory so reflect the retirement of those induced methods.
 - Modified the sandbox contract so that the user is obliged to define
   bli_gemm_ex() instead of bli_gemmnat(). (This change was made in light
   of the *nat() functions no longer existing.) Also updated the existing
   'power10' and 'gemmlike' sandboxes to come into compliance with the
   new sandbox rules.
 - Updated BLISObjectAPI.md, BLISTypedAPI.md, Testsuite.md documentation
   to reflect the retirement of 3m/4m, and also modified Sandboxes.md to
   bring the document into alignment with new conventions.
 - Updated various comments; removed segments of commented-out code.

 Fixed substitution bug in configure.
 
 Details:
 - Fixed a bug in configure related to the building of the so-called
   config list. When processing the contents of config_registry,
   configure creates a series of structures and list that allow for
   various mappings related to configuration families, subconfigs,
   and kernel sets. Two of those lists are built via subsitituion
   of umbrella families with their subconfig members, and one of
   those lists was improperly performing the subtitution in a way
   that would erroneously match on partial umbrella family names.
   That code was changed to match the code that was already doing
   the subtitution properly, via substitute_words().
 - Added comments noting the importance of using substitute_words()
   in both instances.

 Allow use of 1m with mixing of row/col-pref ukrs.
 
 Details:
 - Fixed a bug that broke the use of 1m for dcomplex when the single-
   precision real and double-precision real ukernels had opposing I/O
   preferences (row-preferential sgemm ukernel + column-preferential
   dgemm ukernel, or vice versa). The fix involved adjusting the API
   to bli_cntx_set_ind_blkszs() so that the induced method context init
   function (e.g., bli_cntx_init_<subconfig>_ind()) could call that
   function for only one datatype at a time. This allowed the blocksize
   scaling (which varies depending on whether we're doing 1m_r or 1m_c)
   to happen on a per-datatype basis. This fixes issue 557. Thanks to
   Devin Matthews and RuQing Xu for helping discover and report this bug.
 - The aforementioned 1m fix required moving the 1m_r/1m_c logic from
   bli_cntx_ref.c into a new function, bli_l3_set_schemas(), which is
   called from each level-3 _front() function. The pack_t schemas in the
   cntx_t were also removed entirely, along with the associated accessor
   functions. This in turn required updating the trsm1m-related virtual
   ukernels to read the pack schema for B from the auxinfo_t struct
   rather than the context. This also required slight tweaks to
   bli_gemm_md.c.
 - Repositioned the logic for transposing the operation to accommodate
   the microkernel IO preference. This mostly only affects gemm. Thanks
   to Devin Matthews for his help with this.
 - Updated dpackm pack ukernels in the 'armsve' kernel set to avoid
   querying pack_t schemas from the context.
 - Removed the num_t dt argument from the ind_cntx_init_ft type defined
   in bli_gks.c. The context initialization functions for induced methods
   were previously passed a dt argument, but I can no longer figure out
   *why* they were passed this value. To reduce confusion, I've removed
   the dt argument (including also from the function defintion +
   prototype).
 - Commented out setting of cntx_t schemas in bli_cntx_ind_stage.c. This
   breaks high-leve implementations of 3m and 4m, but this is okay since
   those implementations will be removed very soon.
 - Removed some older blocks of preprocessor-disabled code.
 - Comment update to test_libblis.c.

 Alloc at least 1 elem in pool_t block_ptrs. (560)
 
 Details:
 - Previously, the block_ptrs field of the pool_t was allowed to be
   initialized as any unsigned integer, including 0. However, a length of
   0 could be problematic given that malloc(0) is undefined and therefore
   variable across implementations. As a safety measure, we check for
   block_ptrs array lengths of 0 and, in that case, increase them to 1.

 Fix insufficient pool-growing logic in bli_pool.c. (559)
 
 Details:
 - The current mechanism for growing a pool_t doubles the length of the
   block_ptrs array every time the array length needs to be increased
   due to new blocks being added. However, that logic did not take in
   account the new total number of blocks, and the fact that the caller
   may be requesting more blocks that would fit even after doubling the
   current length of block_ptrs. The code comments now contain two
   illustrating examples that show why, even after doubling, we must
   always have at least enough room to fit all of the old blocks plus
   the newly requested blocks.
 - This commit also happens to fix a memory corruption issue that stems
   from growing any pool_t that is initialized with a block_ptrs length
   of 0. (Previously, the memory pool for packed buffers of C was
   initialized with a block_ptrs length of 0, but because it is unused
   this bug did not manifest by default.)

 Make error checking level a thread-local variable.
 
 Previously, this was a global variable. Setting the value was synchronized via a mutex but reading the value was not. Of course, these accesses are almost certainly atomic, but there is still the possibility of one thread attempting to set the value and then reading the value set by another thread. For correct operation under user threading (e.g. pthreads), this should probably be thread-local with no mutex.

 Arm micro-architecture dispatch (344)
 
 Details:
 - Reworked support for ARM hardware detection in bli_cpuid.c to parse
   the result of a CPUID-like instruction.
 - Added a64fx support to bli_gks.c.
 - include arm64 and arm32 family headers from bli_arch_config.h.
 - Fix the ordering of the "armsve" and "a64fx" strings in the
   config_name string array in bli_arch.c. The ordering did not match
   the ordering of the corresponding arch_t values in bli_type_defs.h,
   as it should have all along.
 - Added clang support to make_defs.mk in arm64, cortexa53, cortexa57
   subconfigs.
 - Updated arm64 and arm32 families in config_registry.
 - Updated docs/HardwareSupport.md to reflect added ARM support.
 - Thanks to Dave Love, RuQing Xu, and Devin Matthews for their
   contributions in this PR (344).

 Use path-based install name on MacOS and use relocatable RPATH entries for testsuite inaries.
 
 - RPATH entries (and DYLD_LIBRARY_PATH) do nothing on macOS unless the install_name of the library starts with rpath/. While the install_name can be set to the absolute install path, this makes the installation non-relocatable. When using path in the install_name, install paths within the normal DYLD_LIBRARY_PATH work with no changes on the user side, but for install paths off the beaten track, users must specify an RPATH entry when linking (or modify DYLD_LIBRARY_PATH at runtime). Perhaps this could be made into a configure-time option.
 - Having relocable testsuite binaries is not necessarily a priority but it is easy to do with executable_path (macOS) or $ORIGIN (linux/BSD).

 Re-enable and fix 8e0c425 (BLIS_ENABLE_SYSTEM).
 
 Details:
 - Re-enable the changes originally made in 8e0c425 but quickly reverted
   in 2be78fc.
 - Moved the include of bli_config.h so that it occurs before the
   include of bli_system.h. This allows the define BLIS_ENABLE_SYSTEM
   or define BLIS_DISABLE_SYSTEM in bli_config.h to be processed by the
   time it is needed in bli_system.h. This change should have been
   in the original 8e0c425, but was accidentally omitted. Thanks to Minh
   Quan Ho for catching this.
 - Add define BLIS_ENABLE_SYSTEM to config_detect.c so that the proper
   cpp conditional branch executes in bli_system.h when compiling the
   hardware detection binary. The changes made in 8e0c425 were an attempt
   to support the definition of BLIS_OS_NONE when configuring with
   --disable-system (in issue 532).  That commit failed because, aside
   from the required but omitted header reordering (second bullet above),
   AppVeyor was unable to compile the hardware detection binary as a
   result of missing Windows headers. This commit, which builds on PR
   546, should help fix that issue. Thanks to Minh Quan Ho for his
   assistance and patience on this matter.

 bli_error: more cleanup on the error strings array
 
 - There was redundance between the macro BLIS_MAX_NUM_ERR_MSGS (=200) and
   the enum BLIS_ERROR_CODE_MAX (-170), while they both mean the same thing:
   the maximal number of error codes/messages.
 - The previous initialization of error messages at compile time ignored that
   the 'bli_error_string' array still occupies useless memory due to 2D char[][]
   declaration. Instead, it should be just an array of pointers, pointing at
   strings in .rodata section.
 - This commit does the two modifications:
    * retired macros BLIS_MAX_NUM_ERR_MSGS and BLIS_MAX_ERR_MSG_LENGTH everywhere
    * switch bli_error_string from char[][] to char *[] to reduce its footprint
      from 40KB (200*200) to 1.3KB (170*sizeof(char*)).
      (No problem to use the enum BLIS_ERROR_CODE_MAX at compile-time,
      since compiler is smart enough to determine its value is 170.)
