Pulse: use async API instead of simple API
Null driver: no audio driver with accurate timing
Add latency setting to alsa, pulse and android drivers
android: start and stop AudioTrack on audiobackend init/term
Simplify audiostream. Get rid of "none" option
This adds the OSS audio backend and removes OSS code from
core/linux-dist/main.cpp and core/sdl/main.cpp.
The OSS backend will be included during compilation if the USE_OSS
flag is set.
Although OSS code in core/linux-dist/main.cpp depended on the
TARGET_PANDORA flag instead of USE_OSS, the latter should work too
since it is defined in the Pandora Makefile (lines 7 & 83).
