This is a PR to include a new vane called `%lick`. This vane allows `%gall` agents to open an IPC communication port on urth. This port speaks in jammed nouns of the form `[=mark =noun]` The vane has three parts: 1. urbit/urbit modifications: urbit/urbit#6519 2. urbit/vere modifications: This PR 3. userspace example: https://github.com/mopfel-winrux/lick-agent
This adds a macro "vere_library" which supports our concepts of debug and
release builds, and gives finer-grained control over which copts/linkopts are
passed and when.
Takes advantage of bazel's "compilation_mode={dbg,opt}" to control
debug/optimized builds.
Old format: `/vere/~.2.10-9fac623`, new format `/vere/[once, live, soon, edge]/~.2.10-9fac623`.
Adds somewhere between 5-10% improvement to wall time. I've ran all tests, booted several fakeships and comets with this installed, and all seems to work properly. Mac x86 is coming, I just don't have access to an intel mac right now [but soon...]. Linux will come later once I figure out some bugs. The following is time to boot a fakeship from a brass pill: ``` Without LTO: ________________________________________________________ Executed in 180.46 secs fish external usr time 17.83 secs 0.10 millis 17.83 secs sys time 0.23 secs 1.86 millis 0.23 secs With LTO: ________________________________________________________ Executed in 164.87 secs fish external usr time 15.65 secs 0.12 millis 15.65 secs sys time 0.19 secs 1.94 millis 0.19 secs ``` 180/164 -> 1.09 --- ~barter-simsum ## Brass pill boot: x86 linux without lto: ~140s x86 linux with lto: ~128s ~ 8.6% improvement - note we may be able to squeeze a bit more out if we can apply `-flto` to all dependencies and not just urbit binaries. This is currently an issue for x86 linux though due to some weird uninvestigated behavior with libsigsegv ## For those curious, the following hints at what was inlined ``` readelf -s ./bazel-bin/pkg/vere/urbit | grep lto_priv 1233: 000000000042d0f0 361 FUNC LOCAL DEFAULT 2 _rebalance.lto_priv.1 1237: 000000000042d6c0 435 FUNC LOCAL DEFAULT 2 _rebalance.lto_priv.0 13002: 0000000000d24a00 200 OBJECT GLOBAL HIDDEN 14 u3_Signal.lto_priv.0 13358: 0000000000d36de0 8 OBJECT GLOBAL HIDDEN 14 sec_u.lto_priv.0 13429: 0000000000d24ae0 80 OBJECT GLOBAL HIDDEN 14 u3V.lto_priv.0 13785: 00000000004516e0 110 FUNC GLOBAL HIDDEN 2 _tap_in.lto_priv.0 14094: 0000000000d3aeb0 4 OBJECT GLOBAL HIDDEN 14 sag_w.lto_priv.0 14100: 0000000000469af0 971 FUNC GLOBAL HIDDEN 2 _lord_stop.lto_priv.0 14120: 00000000004581f0 393 FUNC GLOBAL HIDDEN 2 _cj_nail.lto_priv.0 14178: 0000000000456a30 450 FUNC GLOBAL HIDDEN 2 _cj_fine.lto_priv.0 14732: 0000000000463eb0 82 FUNC GLOBAL HIDDEN 2 _box_free.lto_priv.0 14849: 000000000044a320 658 FUNC GLOBAL HIDDEN 2 _n_find.lto_priv.0 15325: 0000000000478dd0 1487 FUNC GLOBAL HIDDEN 2 _pier_init.lto_priv.0 15413: 00000000004674a0 939 FUNC GLOBAL HIDDEN 2 _ca_willoc.lto_priv.0 15841: 0000000000477300 394 FUNC GLOBAL HIDDEN 2 _dawn_fail.lto_priv.0 16128: 00000000004449d0 1746 FUNC GLOBAL HIDDEN 2 _cr_sing.lto_priv.0 16214: 0000000000474c40 500 FUNC GLOBAL HIDDEN 2 _ttyf_loja.lto_priv.0 16277: 000000000078fe48 8 OBJECT GLOBAL HIDDEN 5 ver_hos_c.lto_priv.0 16887: 0000000000443ab0 460 FUNC GLOBAL HIDDEN 2 _n_bam.lto_priv.0 17346: 000000000045cc90 540 FUNC GLOBAL HIDDEN 2 _cj_minx.lto_priv.0 17897: 0000000000d249e8 8 OBJECT GLOBAL HIDDEN 14 _file_u.lto_priv.0 18325: 00000000004447a0 58 FUNC GLOBAL HIDDEN 2 _n_feb.lto_priv.0 18517: 00000000004453e0 3981 FUNC GLOBAL HIDDEN 2 _n_comp.lto_priv.0 18739: 0000000000d249f6 1 OBJECT GLOBAL HIDDEN 14 _ct_lop_o.lto_priv.0 18880: 000000000044fda0 1650 FUNC GLOBAL HIDDEN 2 _find_home.lto_priv.0 19091: 0000000000474e40 500 FUNC GLOBAL HIDDEN 2 _ttyf_hija.lto_priv.0 19508: 0000000000450420 1393 FUNC GLOBAL HIDDEN 2 _pave_home.lto_priv.0 19595: 000000000042a3d0 687 FUNC GLOBAL HIDDEN 2 _in_uni.lto_priv.0 19822: 0000000000430e20 1095 FUNC GLOBAL HIDDEN 2 _block_rip.lto_priv.0 20236: 0000000000457030 331 FUNC GLOBAL HIDDEN 2 _cj_axis.lto_priv.0 20306: 0000000000457180 514 FUNC GLOBAL HIDDEN 2 _cj_gust.lto_priv.0 20866: 0000000000456c00 667 FUNC GLOBAL HIDDEN 2 _cj_cast.lto_priv.0 21317: 0000000000446fe0 11412 FUNC GLOBAL HIDDEN 2 _n_burn.lto_priv.0 21430: 000000000045c820 1130 FUNC GLOBAL HIDDEN 2 _cj_spot.lto_priv.0 ```
`zlib` 1.3 was [released on August 18, 2023](http://zlib.net/). Fixes recent CI failures as well.
Otherwise devenv fails to work on newer NixOS'es, looks like because th glibc is too old.
