This moves all VP3-specific function pointers from dsputil to a
new vp3dsp context.  There is no reason to ever use the VP3 IDCT
where an MPEG2 IDCT is expected or vice versa.

It turns out that the reference decoder subtracts 128 from DC during block
decode but adds it back during reordering block with zigzag pattern.
Transforming block with incorrect DC caused heavy visual artifacts for
many quantisers.

  libopenjpeg: introduce encoding support
  libopenjpeg: rename decoder source file.
  RTMPTS protocol support
  RTMPS protocol support
  avconv: print an error message when demuxing fails.

This one is tricky. Consider a graph with two sink links, A and B.
request_oldest() requests on A, and A returns EOF. This EOF causes
a filter to flush pending frames to B; they are unrequested.
Then request_oldest() moves on to B, and B returns EOF.

The doxy says, and the heap implementations assumes,
it is in AV_TIME_BASE units.

The image data is in BGR and not in RGB.

channel_map is applied between in and postin.
Without this test, if the input format is an acceptable internal format,
the in->postin conversion is skipped. In the best case,
it ignores channel_map, in the worst case it causes an assert failure
if the number of channels is changed by the map.

Also exit in such a case if -xerror is used.

Fixes bug 329.
