Profiles that read two repositories, a libretro port and its upstream,
now prefix each citation with source or upstream, decided by which tree
carries the cited value at its pin. The emulator pages use the word to
tell libretro glue, emulator code as the port carries it, and the
upstream emulator apart.
Recalbox compiles libretro/mame at 0.258 and 0.278 itself; typed
libretro, both profiles were resolved for every all_libretro platform
although the buildbot RetroArch installs from has neither. A profile
now names the platforms that build it (built_by), and is reached only
when a platform lists it by name.
Recalbox ships libretro/mame built at 0.258 and at 0.278, and no
profile described either release. mame_hash_scraper gains --release,
which reads the BIOS root sets at one mamedev tag and writes a profile
pinned to it; mame0258 and mame0278 are generated from it, every
source_ref anchored at its tag.
