Allow filters to handle larger frames.

For now, check the image size.
Inspired by a patch from Paul B Mahol.

Invalid sizes would be detected later by allocation failures,
detecting problems earlier is cleaner.

Move a subtraction to the other side of the equal to avoid overflows.

This patch enables paletteuse to identify the transparency in incoming
video and tag transparent pixels on outgoing video with the correct
index from the palette.

This requires tracking the transparency index in the palette,
establishing an alpha threshold below which a pixel is considered
transparent and above which the pixel is considered opaque, and
additional changes to track the alpha value throughout the conversion
process.

This change is a partial fix for https://trac.ffmpeg.org/ticket/4443
However, animated GIFs are still output incorrectly due to a bug
in gif optimization which does not correctly handle transparency.

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.

Fixes the following warning:
libavfilter/tests/filtfmts.c: In function ‘main’:
libavfilter/tests/filtfmts.c:103:18: warning: assignment discards ‘const’ qualifier from pointer target type
