Remove doc/dev_communit markup files completely as they are at the wrong place.
Create a new community page, merging all of doc/dev_community and subsection Code of Conduct into a common place.
The corresponding patch to ffmpeg-web puts the Organisation & Code of Conduct into a seperate community chapter on the FFmpeg website.

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.

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().
