b420f23566 cbs_av1: Fix reading of overlong uvlc codes 
The specification allows 2^32-1 to be encoded as any number of zeroes
greater than 31, followed by a one.  This previously failed because the
trace code would overflow the array containing the string representation
of the bits if there were more than 63 zeroes.  Fix that by splitting the
trace output into batches, and at the same time move it out of the default
path.

(While this seems likely to be a specification error, libaom does support
it so we probably should as well.)

From a test case by keval shah <skeval65@gmail.com>.

11dff170ef avcodec/hevcdec: fix non-ref frame judgement 
After inspecting the source code of x265, mpv and ffmpeg, I've found that
ffmpeg mistakenly regards EVC_NAL_BLA_N_LP and HEVC_NAL_IDR_N_LP as non-
reference frames, which are acutally reference frames according to the
specification in x265, and drops them.

This patch should address the problem. I have tested it with mpv.

041231fcd6 libavfilter/vf_yadif: Make frame management logic and options shareable 
I'm writing a cuda implementation of yadif, and while this
obviously has a very different implementation of the actual
filtering, all the frame management is unchanged. To avoid
duplicating that logic, let's make it shareable.

From the perspective of the existing filter, the only real change
is introducing a function pointer for the filter() function so it
can be specified for the specific filter.
