Andreas Rheinhardt 790f793844 avutil/common: Don't auto-include mem.h
There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.

Keep it for external users in order to not cause breakages.

Also improve the other headers a bit while just at it.

avutil/film_grain_params: remove do loop in CHECK macro
The continue statement will break out of the do/while loop, not the
outer loop as intended. This is one (compound) statement anyway, so we
can remove the do/while entirely.

avutil/film_grain_params: remove unused variables
These variables are never read from, so they trigger -Wunused-variables

Niklas Haas a9023377b2 avutil/film_grain_params: add av_film_grain_params_select()
Common utility function that can be used by all codecs to select the
right (any valid) film grain parameter set. In particular, this is
useful for AFGS1, which has support for multiple parameters.

However, it also performs parameter validation for H274.

libavutil: introduce AVFilmGrainParams side data
This patch introduces a new frame side data type AVFilmGrainParams for use
with video codecs which support it.

It can save a lot of memory used for duplicate processed reference frames and
reduce copies when applying film grain during presentation.
