sdl-ios-xcode: src/audio/nto/SDL_nto

annotate src/audio/nto/SDL_nto_audio.c @ 3803:3decf9cdeb63 SDL-ryan-multiple-audio-device

Removed ESD cruft from the core...now the driver will use esound if there's an ESPEAKER variable set for a remote host, or the daemon is already running on the local host, but it won't spawn it. Hopefully this works out okay.
