Intended for use with hardware frames for which rawvideo is not
sufficient.  Requires the trusted packet flag to be set - decoding
fails if not to avoid security issues (the wrapped AVFrame can
contain pointers to arbitrary data).

ret is 0 by default.

This avoids confusion with equivalent H.265 SEI values when both are
being used at the same time.

(cherry picked from commit 6ea220cbee)

Previously in the mpeg2_metadata filter.  Also adds a test.

The bracketing was wrong - '-' binds before '<<'.  This would
previously incorrectly reject the streams in the WP_A and WP_B
conformance tests.

This should be ticks, not time_scale steps - it was wrong for all
framerates not a multiple of 1/2.

This reverts commit a14a12ca13.

The CTU size is always 32x32; the surface size is what actually sets
the desired property, and it is already correct.

Whether the udu string should be freed depends on whether the SEI it
gets added to was created internally by cbs or externally by the bsf.
The current code frees it twice in the former case.

Remove any trailing zeroes from H.26[45] NAL units at the same time.
