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.

only 16b alpha is supported (not 8 bits)

following official encoder, alpha data doesn't impact
yuv plane quality.

So the alpha data encoding is done after the yuv part.
It's also avoid to loose quality in yuv part when
alpha is not uniform.

the alpha encoding funcs is mainly take from prores_ks
encoder, except for the alpha data reorganization

description are based on multimedia wiki documentation

use b64a as src pix fmt (doesn't seems to have an impact on decoding)
but it's the value use by official encoder

The earlier code used the most recent non-auxiliary slice to determine
whether an auxiliary slice has the syntax of an IDR slice, even when
the most recent slice was from a slice of a redundant frame. Now only
slices of the primary coded picture are used, as the specifications
mandate.

Flush the buffered data in libmfx before video param reinit
in case the frames drop.

Cache the first frame causing the reinit and decode zero-size
pkt to flush the buffered pkt before reinit. After all the
buffered pkts being flushed, resume to reinit and decode.

Fix the issue in ticket #7399.

[V2]: Move the definition of zero_pkt to where it is exactly
used.
