Our version of #147. With audio.loose_sounds (off by default), each of a map's sounds that has a Halo PC sound tag file of its name in the data root's tags folder plays from it (port/linux/game/loose_sounds.c); loose_sounds_reload and loose_sounds at the console read them again or give the map's back. The files' samples are made the Xbox ADPCM this build plays through the Custom Edition converter, so no channel pools change and stock maps play as before. The override is written into the map's definition in place, keeping the counters the game updates; a change stops every sound and flushes the sound cache first, and old samples are freed once no cache block holds them. A split sound's length is its chain's. The sound cache is HALO_PORT_SOUND_CACHE_SIZE: 16 MB on desktop, the Xbox's 4 MB on Android, with the debug view's buffer sized to match.
