c1835644f5 h265parser: Allow updating SPS/PPS without parent parameter set 
h265parser defers linking parameter sets until slice header is parsed.
Thus valid SPS/PPS parsed by h265parser can have no linked
parent parameter set. Apply this behavior to
gst_h265_parser_update_{sps,pps} too

be98ba00d7 h266parser: do not fail when extension flags are set 
For VPS, PPS, APS, OPI and DCI, the extension flags are the last syntax
in the structures, and according to the spec, should be ignored if set to 1.

Therefore, we can just ignore them rather than failing.

This fixes a few failures in fluster, like in the PSEXT_A_Nokia_2 stream.

7983ecff1c docs: generate hotdoc configs for libraries with our helper script 
With this patch, configure time is identical no matter whether doc is
enabled or not.

The configuration files also now contain explicitly-listed sources with
no wildcards.

For the four libraries where hotdoc needs to use clang to generate the
documentation (as opposed to the rest of the libraries where hotdoc uses
the gir), the script will call pkg-config to determine the appropriate
C flags.

This means a side effect of this patch is that pkg-config files are now
generated for the gstadaptivedemux and gstopencv libraries.

082a8fcd5e h264parse: parse unregistered SEI without user data 
We get loads of warnings when parsing videos from users:

gsth264parser.c:1115:gst_h264_parser_parse_user_data_unregistered: No more remaining payload data to store
gsth264parse.c:646:gst_h264_parse_process_sei:<h264parse0> failed to parse one or more SEI message

Those are raised because of unregistered SEI without user data.

The spec does not explicitly state that unregistered SEI needs to have
data and I suppose the UUID by itself can carry valuable information.
FFmpeg also parses and exposes such SEI so there is no reason for us no
too as well.

fea8578ee9 codecparsers: Add LCEVC metadata API 
This new metadata API allows elements to attach LCEVC enhancement data to video
buffers. Usually, the video parser elements are charged to parse the LCEVC
enhancement data from SEI Nal units (Supplemental enhancement Information).
However, other elements such as demuxers can also use this API if the LCEVC
enhancement data of the video is stored in a separate stream in the container.

7589647c13 av1parse: Do not return error when expectedFrameId mismatch 
According to the SPEC:
  The frame id numbers (represented in display_frame_id, current_frame_id,
  and RefFrameId[ i ]) are not needed by the decoding process, but allow
  decoders to spot when frames have been missed and take an appropriate action.

So we should just print out warning and should not return error in parser when
mismatching. The decoder itself is already robust to handle the reference missing.

Fixes #3622
