E.g. the inclusion of parser.h comes from a time when
the parser used a H264Context.

This is only needed by h264_cabac.c and h264_cavlc.c.
Also fix up the other headers while at it.

The only thing that is actually used directly from there is the
PART_NOT_AVAILABLE constant, which can be moved to h264pred.h.
Otherwise it only depends on other indirectly included headers.
"qf->frame" ref to input frame but it isn't released. av_frame_unref()
is added before refering qf->frame to new frame to make sure the previous
reference is released.

Add transform_skip option to hevc_qsv. By enabling this option,
the transform_skip_enabled_flag in PPS will be set to 1.
This option is supported on the platform equal or newer than ICL.

Add low latency P-pyramid support to qsv. This feature relates to
command line option "-p_strategy". To enable this flag, user also
need to set "-bf" to 0. P-strategy has two modes "1-simple" and
"2-pyramid". The details of the two models refer to

For high/main profile, user can choose to use cavlc by specify "-coder cavlc",
for default, it'll will use cabac, if it's baseline, we'll use cavlc by specs anyway.

The current size is AV_NUM_DATA_POINTERS (i.e. eight).
This number is chosen in order to minimize the amount of allocations
for AVFrame.extended_(data|buf) for audio; it is meaningless
for video for which four is sufficient. So decrease this array
in order to minimize what is copied in ff_mpeg_ref_picture()
and at the places that copy a whole MpegEncContext.
Also do the same for snowenc.

RV40, SVQ3 and VP7/VP8 are eight-bit only, so it makes no sense
to check for them in the codepath initializing > eight bit contexts.
Move the codec-specific code to a switch located after the eight-bit
init code where this is easily possible; and add checks to the macro
to enable the compiler to remove the remaining checks when initializing
bitdepths > 8 at compile-time.

MSDK vc1 and av1 sometimes output frame into the same suface, but
ffmpeg-qsv assume the surface will be used only once, so it will
unref the frame when it receives the output surface. Now change
it to unref frame according to queue count.

FLAC parser currently uses AVFifoBuffer in a highly non-trivial manner,
modifying its "internals" (the whole struct is currently public, but no
other code touches its contents directly). E.g. it does not use any
av_fifo functions for reading the FIFO contents, but implements its own.
Reimplement the needed parts of the AVFifoBuffer API in the FLAC parser,
making it completely self-contained. This will allow us to make
AVFifoBuffer private.
Return an error directly if pixfmt is not supported for encoding, otherwise
it may be hidden until query/check in MSDK.
