8224e837ef audioOutput_alsa: add use_mmap, period_time, buffer_time options 
ALSA support in libao supports configuring of these variables,
and some hardware setups may benefit from having these things
as tweakable.

3c8e88b053 audioOutput_alsa: calculate period size from sample rate 
... instead of hard-coding it to a ridiculously high value that
makes bandwidth-starved devices unhappy.

libao (in SVN) does the same thing, and this calculation was indeed
taken from it.

Low-bandwidth USB (1.1) sound devices seem to need this to prevent
underrun / broken pipe errors (during hw setup, no less) from being
triggered.

b4df8b8f88 De-inline non-trivial, non-performance-critical functions 
Functions that should stay inlined should have an explanation
attached to them.

30df7d49c5 Reverting patch to "fix" the alsa plugin when used with dmix. It ended up breaking the alsa rate plugin, and dmix seems to work fine without it. Thanks to Skee from #mpd for testing.

e8a54efe41 gcc 2.95 fixes 
audioOutput_osx.c, aac_decode.c, mp4_decode.c have NOT been thoroughly
checked, but I nevertheless managed to eyeball and fix one
incompatibility in audioOutput_osx.c

All other files have been build successfully with gcc 2.95

b5e55a648f we ne allow audioOutput plugins to set the final outAudioFormat that will be used. we now use alsa's _near functions to detect what to use.

to be a "blip" for alsa devices, needs more work
