annotate src/audio/macrom/SDL_romaudio.c @ 3816:9d070c1a45fa SDL-ryan-multiple-audio-device

Moved AudioBootstrap section in converted drivers to bottom of source, so I could delete the predeclarations (one more thing to forget to update when changing the API, otherwise). There're a few other cleanups that snuck into this commit, too.
