one the block resides in.

68f8d33bec Support >8bit per component YUV in FFV1. 
decoding becomes slower, encoding becomes faster, with gcc on duron.
some inlining overrides like av_flatten are added to keep inlining similar
to before.

217d34e307 Force speed irrelevant calls to get/put_symbol() to be noinline. 
We need to change decode_line to always_inline because gcc decided not to inline
it anymore once we force some calls to get/put_symbol() to be non inlined and
this decision of gcc would lead to a 10% overall speed loss.
100k smaller object file, no speed change

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.
