It results in undefined behaviour. Instead initialize the mutexes
and condition variables once during init (and check these
initializations).
Also combine the corresponding mutex and condition variable
into one structure so that one can allocate their array
jointly.

This function is only called from the decoder's init function
and given that this decoder has FF_CODEC_CAP_INIT_CLEANUP set,
hevc_decode_free() is called automatically (currently it would
be called twice with the second call being redundant).

Currently the format listing misses the J formats completely, yet
they are marked as supported in the encoder. Thus to make the logic
support them while not explicitly listing them, make the logic
utilize chroma subsampling information in both width and height
available through the pixel format descriptor.
Enable dynamic QP configuration in runtime on qsv encoder. Through
AVFrame->metadata, we can set key "qsv_config_qp" to change QP
configuration when we encode video in CQP mode.

Forgotten in 4011a76494.
The reason for this is that these functtions are marked
as av_always_inline and GCC does not emit warnings
if such functions are unused, so this went unnoticed.

Whether an ICC profile is present or not, the libjxl
encoder wrapper should now properly read colorspace tags
and forward them to libjxl appropriately, rather than just
assume sRGB as before. It will also print warnings when
colorimetric assumptions are made about the input data.

The intention behind the current check seems to be to check for
the rbsp_trailing_bits() syntax structure which is always 0x80
for valid SEI messages. Yet this is wrong: These trailing bits
are not part of the GetBitContext -- they have already been
stripped in ff_h2645_packet_split(). And it is harmful, as
0x80 is a legal SEI message payload type (namely for
Structure of pictures information SEI messages). We ignore this
type of SEI, but because of this bug we also ignored every
SEI message in the same NALU following it.

It does not exist for NALUs for which the SODB is empty;
it also does not exist for NALUs for which not even
the complete header is present. The former category contains
end of sequence and end of bitstream units. The latter category
consists of one-byte HEVC units (the ordinary H.264 header is only
one byte long).
This commit therefore stops stripping RBSP trailing padding
from the former type of unit and discards the latter type of unit
altogether.
This also fixes an assertion failure: Before this commit, a one-byte
HEVC NALU from an ISOBMFF packet could pass all the checks in
hevc_parse_nal_header() (because the first byte of the size field
of the next unit is mistaken as containing the temporal_id);
yet because the trailing padding bits were stripped, its actually
had a size of less than eight bits; because h2645_parse.c uses
the checked bitstream reader, the get_bits_count() of the GetBitContext
is not 16 in this case; it is not even a multiple of eight
and this can trigger an assert in ff_hevc_decode_nal_sei().
