Log:

Merge mythtv-hdaudio branch back into trunk.


Major changes include:

Multichannel analog or LPCM output up to 7.1 channels
Support audio bit depth > 16 bits (24 bits, 32 bits and float)
SSE enhanced sample format conversion
Downmix capability
Automatic conversion to format supported by the hardware (bit depth, samplerate, channels) 
(Almost) lockless audiobuffer

The list of fixes is quite long, highlights include:

Improved buffering in mythmusic, aobase and aoalsa, fewer underruns
Mythmusic CD playback buffering fixes
Timecode fixes / avsync improvements
Performance improvements
Fix multichannel volume control
Fix multichannel audio, stereo output for a range of codecs
Pulseaudio fixes (ALSA still preferred for quality and performance reasons)
Output is completely free of clipping
Clean up, fixes and improvements for every output class
Add some code documentation

You will need to perform a rebuild of your plugins
