Calling a function via a different function pointer type is
undefined behavior (C11, 6.3.2.3 8); two pointer parameters
of different type are not equivalent in this regard, although
it happens to work in practice; the current code relies on this.
This patch brings the code in line with the spec. This fixes the
following FATE-tests when run with Clang-UBSan:
ac3-fixed-encode-2 audiomatch-afconvert-{16000,44100}-mono-he-{adts,m4a}
audiomatch-dolby-44100-mono-he-mp4 filter-metadata-avf-aphase-meter-mono
filter-pan-{downmix1,downmix2,mono2,stereo2,stereo3,stereo4,upmix1,upmix2}
lavf-dv_{pal,ntsc} matroska-encoding-delay
The error was something like
src/libswresample/rematrix.c:621:17: runtime error: call to function sum2_float through pointer to incorrect function type 'void (*)(void *, const void *, const void *, void *, int, int, int)

In parse_cinespace(), memory allocated in in_prelut[] and out_prelut[]
would leak if allocate_3dlut() failed. Replace return ret with goto end
to free memory before return error code.

In put_main_header(), av_mallocz() allocates memory to local variable
buffer, buffer leaks if av_mallocz() to *out failed. Add av_free(buffer)

The ret value is checked later on again, so this check
is redundant and would cause the frame to not be unrefd on
failure as well.
So remove this check and add one before av_frame_remove_side_data
to ensure it is not called with an invalid frame.

This would make the goto dead code and also would not properly

Add handling here for

Also add parentheses to make behaviour a little more explicit,
where &&'s precedence over || was relied on previously.

h264_annexb_insert_sps_pps (called after write_packet)
reorganizes PPS, SPS, and IDR packets in H.264 streams.
Since write_packet already validates pkt,
redundant null checks in h264_annexb_insert_sps_pps can be removed.

Since 155508c6e9 specifying multiple
bsfs for different streams was broken:
"[bsfs/a=h264_metadata:bsfs/v=h264_metadata]out.mp4|..."
This incorrectly only parsed the first bsfs specification. The reason
for this is that the dictionary is modified in the iterator, hence
invalidating the iterator. The simplest fix for this is to simply
iterate from the beginning in each loop given that the previous entry
is removed.
The way streams are coded in an IAMF struct follows a scalable model where the
channel layouts for each layer may not match the channel order our API can
represent in a Native order layout.
For example, an audio element may have six coded streams in the form of two
stereo streams, followed by two mono streams, and then by another two stereo
streams, for a total of 10 channels, and define for them four scalable layers
with loudspeaker_layout values "Stereo", "5.1ch", "5.1.2ch", and "5.1.4ch".
The first layer references the first stream, and each following layer will
reference all previous streams plus extra ones.
In this case, the "5.1ch" layer will reference four streams (the first two
stereo and the two mono) to encompass six channels, which does not match out
native layout 5.1(side) given that FC and LFE come after FL+FR but before
SL+SR, and here, they are at the end.
For this reason, we need to build Custom order layouts that properly represent
what we're exporting.
