26d7af4c38 aarch64: vp8: Fix assembling with clang 
This also partially fixes assembling with MS armasm64 (via
gas-preprocessor).

The movrel macro invocations need to pass the offset via a separate
parameter. Mach-o and COFF relocations don't allow a negative
offset to a symbol, which is handled properly if the offset is passed
via the parameter. If no offset parameter is given, the macro
evaluates to something like "adrp x17, subpel_filters-16+(0)", which
older clang versions also fail to parse (the older clang versions
only support one single offset term, although it can be a parenthesis.

317b7b06fd avcodec/cuviddec: Add support for decoding HEVC 4:4:4 content 
This is the equivalent change for cuviddec after the previous change
for nvdec. I made similar changes to the copying routines to handle
pixel formats in a more generic way.

Note that unlike with nvdec, there is no confusion about the ability
of a codec to output 444 formats. This is because the cuvid parser is
used, meaning that 444 JPEG content is still indicated as using a 420
output format.

83c7ac2e47 avcodec/nvdec: Explicitly mark codecs that support 444 output formats 
With the introduction of HEVC 444 support, we technically have two
codecs that can handle 444 - HEVC and MJPEG. In the case of MJPEG,
it can decode, but can only output one of the semi-planar formats.

That means we need additional logic to decide whether to use a
444 output format or not.

e06ccfbe1d avcodec/nvdec: Add support for decoding HEVC 4:4:4 content 
The latest generation video decoder on the Turing chips supports
decoding HEVC 4:4:4. Supporting this is relatively straight-forward;
we need to account for the different chroma format and pick the
right output and sw formats at the right times.

There was one bug which was the hard-coded assumption that the
first chroma plane would be half-height; I fixed this to use the
actual shift value on the plane.

We also need to pass the SPS and PPS range extension flags.

f4ea930a11 avcodec/hevc_ps: Expose all SPS and PPS range extension flags 
We need all the flags to be exposed to be able to pass them on to
HW decoders. I did not attempt to nuance any of the warnings about
flags being unsupported as there's no way, at the point we extract
flags, to say whether an HW decoder is being used.
