Zopfli & ZopfliPNG KrzYmod win/lin builds v18.8.2

(all builds are PGO-ed & LTO-ed)

Changelog:

• Add --v6 to display more information with --all switch,
• Display mode used in threads progress display: xxx1 - lazy, xx1x - ohh, x1xx - rc, 1xxx - brotli (e.g. 0011 means that lazy and ohh modes are used),
• Speed up threads progress refresh 2x,
• Improve result validating speed with --all switch, especially visible in "small amount of iterations" runs,
• Allow passing optional numeric parameter next to --testrec switch to change the default of 20 maximum unsuccessful tries to some other number (this number can still be exceeded with threads),
• Fix display update regression with threads and --v>2,
• Fix inefficient threading on --v<3 (including default),
• Fix wrong buffer size,
• Fix excessive CPU usage with MASTER controller thread when more SLAVE threads finished their work and are idle, and verbosity <3 or default,
• Code should now be also OS X portable including threads and their affinity setting, thanks to MegaByte,
• --testrec is now multithreaded,
• Every memory allocator now uses built-in wrapper which shouldn't crash Zopfli on out of memory or heap fragmentation, instead will throw an error and wait for memory to become available. Retried every minute,
• Fix wrong time offset in ZIP files,
• CTRL+C will now properly abort program when --mui is already set to 1,
• Display block splitter counters only on verbosity level 5,
• Ratio is now a compression ratio not the % of original,
• Block progress is now displayed when the block compression finishes not starts and it's a bit improved,
• Use B, KB, MB in Data Left,
• Add ZOPFLI_REALLOC_BUFFER for TraceBackwards and ZopfliStoreLitLens for a small speed up of ~2% (measured on Odroid U3),
• Fix other verbosity issues.

Zopfli KrzYmod win/lin builds v18.2.7

This version adds a lot of improvements, mainly by extending block splitting functionality, as well as affinity setting and fixes ARM CPU crashes bug existing since the original. New switches:
--aff#
--maxrec
--sb#
--slowdyn#
--testrec#

Renamed/Removed switches:
--slowsplit was renamed to --slowfix,
--v6 was removed, maximum verbosity level is now 5.

All are built using LTO and PGO.

Zopfli KrzYmod win x64 AVX build v16.5.30

This version has best statistics database support stored in ZopfliDB directory (automatically created) when --statsdb command is used. This allows to resume blocks iterating or produce max compressed deflate stream in seconds when number of iterations zopfli is run with is lower than best statistic / block file indicates (in other words if such file exists, block crc32 and size matches).
