Use GPB frames to replace regular P/B frames if backend driver does not
support it.
- GPB:
Generalized P and B picture. Regular P/B frames replaced by B
frames with previous-predict only, L0 == L1. Normal B frames
still have 2 different ref_lists and allow bi-prediction

On empty input the awk script was always successful which caused the
filter-refcmp tests to always succeed.
Also fix the command lines for refcmp_metadata compare function because it
needs auto conversion filters, and update reference of test
filter-refcmp-psnr-rgb because it was missed in
a7fc78c1a6 but was never noticed due to the
original issue...

The guess_palette() implementation is questionable in itself
as its results don't match those from other DVD subtitle decoders.
This commit starts cleanup by fixing an obvious bug which has made
certain DVD subs appear yellow instead of white or grey for more than
10 years..

A bug was found in dav1d <= 1.0.0 where the event flag New Sequence Header would
not be signaled for some samples using delayed random access points.
It has since been fixed, but nonetheless it's best to ensure the AVCodecContext
is filled with parameters when parsing the first frame, regardless of what events
were signaled.
Fixes ticket #9694.

If the svt equivalent option to an avctx AVOption is passed by the user
then it should have priority. The exception are fields like dimensions, bitdepth
and pixel format, which must match what lavc will feed the encoder after init.
This addresses libsvt-av1 issue #1858.

The init_pool_size is set to be 64 and it is too many.
Use IOSurfQuery to get NumFrameSuggest which is the suggested
number of frame that needed to be allocated when initializing the decoder.
Considering that the hevc_qsv encoder uses the most frame buffer,
async is 4 (default) and max_b_frames is 8 (default) and decoder
may followed by VPP, use NumFrameSuggest + 16 to set init_pool_size.

Since ffmpeg-qsv uses return value to reinit decoder, it doesn't need to
decode header each time. Move qsv_decode_header's position so that
it will be called only if codec needed to be reinitialized.
Rearrange the code of flushing decoder and re-init decoder operation.
Remove the buffer_count and use the got_frame to decide whether the
decoder is drain.

Commit e050959103 implemented passing in
modifiers by using the PRIME_2 memory type, which only exists in v2 of
the library.
To still support v1 of the library, conditionally compile using
VA_CHECK_VERSION() for both the new code and the old code before
the commit.
Note PRIME_2 memory was introduced from VA-API 1.1, so use
VA_CHECK_VERSION(1, 1, 0) instead of VA_CHECK_VERSION(2, 0, 0) (Haihao)

In case the BSF has not been drained before flushing/closing,
the context's next_frame might be set; yet it is not freed
in flush or close. The former only zeroes it (which automatically
causes a leak in case it was set). So do this when closing
and flushing.

Since the switch to the new FIFO API in commit
ea511196a6, the FIFO is always
grown by the amount of data intended to be written into it
even in case the FIFO has enough free space. Fix this by
only growing the FIFO if needed and then only by the amount that is
actually needed.
The allocation errors that resulted from this uncovered another bug:
The context is left in an inconsistent state in case the FIFO can't
be grown, because the FIFO does not contain as much data as the sizes
contained in the PacketDesc list claim. This led to an infinite loop
in output_packet() (called from mpeg_mux_end()).
Fix this by growing the FIFO before adding a new PacketDesc element,
thereby preventing the context from becoming inconsistent.

This is possible, because every given FFCodec has to implement
exactly one of these. Doing so decreases sizeof(FFCodec) and
therefore decreases the size of the binary.
Notice that in case of position-independent code the decrease
is in .data.rel.ro, so that this translates to decreased
memory consumption.

This increases type-safety by avoiding conversions from/through void*.
It also avoids the boilerplate "AVFrame *frame = data;" line
for non-subtitle decoders.

sizeof(FFCodec), yet this can be more than offset lateron.
