As the values generated by av_bmg_get can be arbitrarily large
(only the stddev is specified), we can't use a fixed tolerance.
Calculate a dynamic tolerance (like in float_dsp from 38f966b2),
based on the individual steps of the calculation.

This fixes running this test with certain seeds, when built with
clang for mingw/x86_32.

It is not uncommon to find code where the caller thinks to know better
what the return value should be than the callee. E.g. something like
"if (av_new_packet(pkt, size) < 0) return AVERROR(ENOMEM);". This commit
changes several instances of this to instead forward the actual error.

Add -tile_rows and -tile_cols option to specify the number of tile rows
and columns for ICL+ (gen 11) platform.

A tile must wholly contain all the slices within it. Slices cannot cross
tile boundaries. So the slice number would be implicitly resized to the
max(nSlice, nTile).

Example:
    ffmpeg -v verbose -hwaccel qsv -init_hw_device qsv=hw
    -filter_hw_device hw -f rawvideo -s:v 1920x1080 -i ./input.nv12 -vf
    format=nv12,hwupload=extra_hw_frames=64 -c:v hevc_qsv -tile_rows 2
    -tile_cols 2 -slices 4 -y output.h265

Also dump the actual quantity of encoded tiled rows and columns in run
time.

Fix the enhancement #8400.

Implemented according to the specification at https://www.iso.org/standard/69561.html
The 'mhm1' sample entry is registered with MP4RA, which is defined as MHAS encapsulated single stream MPEG-H 3D Audio.
'MHAS' stands for MPEG-H audio stream, which contains encoded audio data and corresponds metadata for decoding.
This patch enables extracting the MHAS bitstream from MP4 and remuxing into MP4.

Taking into account the code

fb(2, ar_coeff_lag);
num_pos_luma = 2 * current->ar_coeff_lag * (current->ar_coeff_lag + 1);
if (current->num_y_points)
    num_pos_chroma = num_pos_luma + 1;
else
    num_pos_chroma = num_pos_luma;

Max value for ar_coeff_lag is 3 (two bits), for num_pos_luma 24, and for
num_pos_chroma 25.

Both ar_coeffs_cb_plus_128 and ar_coeffs_cr_plus_128 may have up to
num_pos_chroma values.

The tremolo filter uses floating point internally, and uses
multiplication factors derived from sin(fmod()), neither of
which is bitexact for use with framecrc.

This fixes running this test when built with for mingw/x86_32
with clang.

In this case, a 1 ulp difference in the output from fmod() would
end up in an output from the filter that differs by 1 ulp, but
which makes the lrint() in swresample/audioconvert.c round in a
different direction.
