41e1354c10 proresenc: Properly account for alpha plane 
The packet buffer allocation considers the alpha channel as DCT-coded,
while it is actually run-coded and thus requires a larger buffer.

45ce880a9b proresenc: Realloc if buffer is too small 
The buffer allocation may be incorrect (e.g. with an alpha plane),
and currently causes the buffer to be set to NULL by init_put_bits,
causing a crash later on.

So, detect that situation, and if detected, reallocate the buffer
and ask for a sample that shows the problem.

b0352b1997 avcodec: export motion vectors in frame side data on demand 
The reasoning behind this addition is that various third party
applications are interested in getting some motion information out of a
video "for free" when it is available.

It was considered to export other information as well (such as the intra
information about the block, or the quantization) but the structure
might have ended up into a half full-generic, half full of codec
specific cruft. If more information is necessary, it should either be
added in the "flags" field of the AVMotionVector structure, or in
another side-data.

This commit also includes an example exporting them in a CSV stream.

4ddb3a6df0 gifdec: use truncated width for image manipulation 
Some files seem to have an off-by-one error. In most cases, it appears to
be on the image width. Therefore, if the decoded image doesn't fit in the
screen:
- If it is wider than the screen (and the lzw decoding buffer), reject it;
- Otherwise, decode the indicated amount, but only write a truncated amount
  to the screen.

Fixes ticket #3538.
