avcodec: add API for automatic handling of icc profiles
...
This functionally already exists, but as pointed out in #9672 and #9673 ,
requiring users to manually include filters is clumsy, error-prone and
hard to use together with tools like ffplay.
To streamline ICC profile support, add a new AVCodecContext flag to
globally enable reading and writing ICC profiles, automatically, for all
appropriate media types.
Note that this commit only includes the new API. The implementation is
split off to separate commits for readability.

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.
