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.

8fa36ae09d This fixes error handling for BeOS, removing the need for some ifdefs. 
AVERROR_ defines are moved to avcodec.h as they are needed in there as well. Feel free to move that to avutil/common.h.
Bumped up avcodec/format version numbers as though it's binary compatible we will want to rebuild apps as error values changed.
Please from now on use return AVERROR(EFOO) instead of the ugly return -EFOO in your code.
This also removes the need for berrno.h.

56419683b2 I still don't think this should be here. Note: without this code DV encoder 
will accept incorrect pix_fmt's and such, but decoder will work much better
with containers not setting the same attributes. It seems like there will
be a generic mechanism for checking such constraints, but if not I can always
resurrect this check for *encoder* only.

6df5f6ae51 size[0-3] are not initialized (and can get random negative trash 
values), so the comparison with vs_total_ac_bits is messed up on the
first couple loop iterations, leading to AC underflows.

the b->prev[] pointers were not being maintained correctly. We
potentially have to update b->prev[] both before and after the area
whose VLC length is getting adjusted.

this also might fix the ppc regression failure?

e15c330246 * 3x encoding speedup. Finally we seem to be on par with libdv 
in terms of time and we're doing slightly better w.r.t. to
     quality. I don't think there's much room for improvement
     left, but I'd like to try and vectorize a couple of things.
     Btw, any ideas on what may impact performance will be greatly
     appreciated.

   * dv1394.c and avidec.c were hooked up with general DV demuxer.

   * DVAUDIO is dead! Long live pcm_s16le!

   * DV audio is now always recognized -- which means we can
     now hear all those ducks quaking in pond.dv.
