3x faster decode_subframe_fixed().
overall flac decoding: 10% faster if file was encoded with fixed predictors.

subject: [FFmpeg-devel] [PATCH] Bugfix: decoding 8- and 24-bit FLAC files
Originally committed as revision 9286 to svn://svn.ffmpeg.org/ffmpeg/trunk
difference to avcodec_decode_audio() is that the user can pass the allocated size of the output buffer to the decoder and the decoder can check if theres enough space

demuxer and decoder layers by enabling the FLAC decoder to decode data
without needing the entire file, from start to finish

only change context if frame header is error-free, as some fields may not be stored in the frame header and so a single damaged frame-header may trash them

less spam/av_log
fix synccode search
channel_order -> decorrelation_type (cosmetic i know, but the old name is too meaningless IMHO)
faster mid/side decorrelator based upon lifting transforms
Originally committed as revision 2793 to svn://svn.ffmpeg.org/ffmpeg/trunk
fix data types of residual&decoded
fix twos complement bitfields
fix utf8 (no, utf8 is not the same as the simple and compact uvlc used in nut)
add truncated bitstream support, both ogg and flac demuxers in mplayer cvs provide incomplete frames, and furthermore it isnt possible to find frameboundaries in flac without decoding it completly
add escape-less golomb rice decoder (=flac style golomb rice) (ultra efficient, the longest vlc code is just 2^32-1 bits)
printf->av_log
fix bps for non independant channels
fix a few +-1 bugs
fix sample order for independant channels
fix data_size
