Mark Thompson e339411691 vaapi: Always free parameter buffers after vaEndPicture() with libva2 
This is an ABI change in libva2: previously the Intel driver had this
behaviour and it was implemented as a driver quirk, but now it is part
of the specification so all drivers must do it.

Mark Thompson bd211bb866 vaapi: Remove H.264 baseline profile 
This has been deprecated in libva2 because hardware does not and will not
support it.  Therefore never consider it for decode, and for encode assume
the user meant constrained baseline profile instead.

Jorge Ramirez-Ortiz 44188993a1 avcodec/v4l2: set sizeimage param for non-raw buffers [fixes #6716] 
Some V4L2 drivers fail to allocate buffers when sizeimage is not set
to a max value. This is indeed the case for s5p-mfc [1]

Most drivers should be able to calculate this value from the frame
dimensions and format - or at least have their own default.

However since this work around should not impact those drivers doing
the "right thing" this commit just provides such a default.

The calculations were extracted from the v4l2 driver used to develop
the ffmpeg v4l2_m2m support [2]. See venc.c and vdec.c
