This patch populates the third entry for HLS codec attribute using the
AAC profile.
The HLS specifications[1] require this value to be the Object Type ID as
referred to in table 1.3 of ISO/IEC 14496-3:2009[2].
The numerical constants in the code refer to these OTIs minus one, as
documented in commit 372597e[3], confirmed by comparing the values in the
code with the values in the table mentioned above.

Fixes ffplay playback of unknown layouts, when SDL directly supports the audio
format, such as:
ffplay -f lavfi anullsrc=cl=2C,aformat=s16
Without the patch, "Channel layout change is not supported" errors are
generated because buffersrc (unknown 2 channel) and buffersink (stereo)
negotiated a stereo layout, but the stereo layout was never stored in the
BufferSourceContext.
This fixes a regression of 7251f90972, but this
is more of a regression of the avfilter channel layout conversion
(1f96db959c).

The mpegts code historically tries to strip (the first) metadata access unit
header from synchronous KLV metadata, but the detection for such streams was
unreliable causing strips of asynchronous metadata or ID3 as well.
MISB ST 1402 specifies required stream type, stream id and registration
descriptor (which eventually maps to the codec ID) so let's use all of these
for reliable detection.

Previously to support dynamic reconfigurations of the matrix string (e.g. 0m),
the rdiv values would always be cleared to 0.f, causing the rdiv to be
recalculated based on the new filter. This however had the side effect of
always ignoring user specified rdiv values.
Instead float user_rdiv[0] is added to ConvolutionContext which will store the
user specified rdiv values. Then the original rdiv array will store either the
user_rdiv or the automatically calculated 1/sum.
This fixes trac ticket #10294, #10867.

Previously, the following syntax elements were not read in the case
sps_num_subpics_minus is 0:
* sps_subpic_id_len_minus1
* sps_subpic_id_mapping_explicitly_signalled_flag
* sps_subpic_id_mapping_present_flag
* sps_subpic_id[i]
This was causing failures to decode bitstreams, for example the DVB's
"VVC HDR UHDTV1 OpenGOP 3840x2160 50fps HLG10 PiP" V&V bitstream.
Patch fixes this by moving the reads for these syntax elements out a
scope.

The SEI message read/write functions are called
via function pointers where the SEI message-specific
context is passed as void*. But the actual function
definitions use a pointer to their proper context
in place of void*, making the calls undefined behaviour.
Clang UBSan 17 warns about this.
This commit fixes this by adding wrapper functions
(created via macros) that have the right type that
call the actual functions. This reduced the number of failing
FATE tests with UBSan from 164 to 85 here.

This together with adjusting the inclusion define allows for the
build to not fail with latest Vulkan-Headers that contain the
stabilized Vulkan AV1 decoding definitions.
Compilation fails currently as the AV1 header is getting included
via hwcontext_vulkan.h -> <vulkan/vulkan.h> -> vulkan_core.h, which
finally includes vk_video/vulkan_video_codec_av1std.h and the decode
header, leading to the bundled header to never defining anything
due to the inclusion define being the same.
This fix is imperfect, as it leads to additional re-definition
warnings for things such as
VK_STD_VULKAN_VIDEO_CODEC_AV1_DECODE_SPEC_VERSION. , but it is
not clear how to otherwise have the bundled version trump the
actually standardized one for a short-term compilation fix.

The channel designation metadata should not override the number of channels.
Let's warn the user if it is inconsistent, and keep the channel layout
unspecified.
Before the conversion to the channel layout API the code only set the mask, but
never overridden the channel count, so this restores the old behaviour.

Existing code could have caused wrong channel order signalling or reduced
channel count if a channel designation appeared multiple times. This is
actually an old bug, but the conversion to the new channel layout API made it
visible, because now the code overrides the proper channel count with the one
calculated from the mask.

The new API requires an extra array member at the very end,
which old API users did not do.
This disables in-place RDFT transforms and instead
does the transform out of place by copying once, there shouldn't
be a significant loss of speed as our in-place FFT requires a reorder
which is likely more expensive in the majority of cases to do.
