It is currently abused to store packet size, which breaks
AV_CODEC_FLAG_COPY_OPAQUE.
Use stream_index instead, which is unused in libavcodec and has the
same type as size.

If the packets returned by libvpx and our internal frame properties
queue get desynchronized for some reason (should not happen, but it is
not clear libvpx API guarantees this), we will keep adding to the queue
indefinitely and never remove anything.
Change the code to drain the queue even if timestamps do not match.
This AVFifo is used to propagate HDR metadata from input frames to
output packets, since libvpx does not allow passing through arbitrary
user data.
It will be extended to pass through other kinds of data in future
commits, so give it a more generic name.
It is not used, except to check whether the packet is valid before
writing HDR metadata to the packet in storeframe(). However, that check
serves no purpose, as the encoded packet is already treated as valid
higher up in this function.

MSDK/VPL uses 420 chroma format as default to encode RGB, and this is
not a proper usage. Now enable 444 encoding for RGB input by default.
When main profile is used, RGB input is still encoded in 420 format.

Note that Screen-Extended Main 4:4:4 and 4:4:4 10 supports
chroma_format_idc from 0, 1 or 3, hence both 420 and 444 are
supported.

Screen Content Coding allows non-intra slice in an IRAP frame which can
reference the frame itself, and would mark the current decoded picture
as "used for long-term reference", no matter TwoVersionsOfCurrDecPicFlag(8.1.3),
hence some previous restricts are not suitable any more.
Constructe RefPicListTemp and RefPicList according to 8-8/9/10. Disable
slice decoding for SCC profile to avoid unexpected error in hevc native
decoder and patch welcome.

According to 7.3.6.1, use_integer_mv_flag should be parsed if
motion_vector_resolution_control_idc equals to 2. If not present, it
equals to motion_vector_resolution_control_idc.

1. Add extension syntax according to 7.3.2.2.3/7.3.2.3.3 in T-REC-H.265-201911.
2. Keep using parsed PPS when bitstream overread for compatibility. For
example, the clip PS_A_VIDYO_3.bit in FATE test has incomplete extension
syntax which will be overread and un-decodable if without this change.
3. Format brace in pps_range_extensions().
