flac fixes:
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...

multithreaded/SMP motion estimation

to try it, run configure --enable-pthreads and ffmpeg ... -threads <num>
the internal thread API is a simple AVCodecContext.execute() callback which executes a given function pointer with different arguments and returns after finishing all, that way no mutexes or other thread-mess is needed outside pthread.c...
