Each libretro profile records version_basis and core_version is read
there at its pin. snes9x states 1.63 in snes9x.h, nestopia 2.0.0, mgba
0.11.0, vice 3.10, atari800's libretro tree 7.0.0. Cores whose build
takes its version from git carry the nearest tag in describe form
(flycast v2.7-90-ge88b0ce, ppsspp, duckstation, gearcoleco), placeholders
copied from .info files (Git, SVN) are replaced by the code's statement,
and a code that states none is null with kind none.
Read at each pinned commit: Azahar, Citra, Citra 2018, Panda3DS, Trident,
FS-UAE and Stella read these below the frontend save directory, Dolphin
and Ishiiruka below <save>/User, Cemu its MLC below <save>/Cemu. Each
profile names its library_name. Citra Canary reads sysdata from the
host data directory: its pin moves to the canary branch it is built from.
49 libretro cores had type: game/utility/test instead of type: libretro,
breaking the all_libretro filtering in resolve_platform_cores and
excluding them from platform packs (e.g. cannonball missing from
RetroArch). core_classification already carries the descriptive role.
9 profiles with subdirectory-loading cores (cannonball/, nxengine/,
Citra/sysdata/, mame2003/, mame2003-plus/, mame2010/) now have path:
fields so cross-reference places files at the correct destination.
resolve_local_file now tries basename when name contains a path
separator (e.g. res/tilemap.bin -> tilemap.bin), fixing resolution
of files with subdirectory names.
