In direct_search() and ff_estimate_b_frame_motion(), penalty_factor
would be used before being initialized in estimate_motion_b(). Also,
the initialization would happen more than once unnecessarily.
ssd_int8_vs_int16 is only called from encode_block()
in svq1enc.c; it calls it in stages: At stage 0,
the int16_t array contains the difference of two
uint16_t. At each of the following stages, the
int16_t array is filled by subtracting an int8_t from
the current stage's int16_t array. The maximum stage
is five, so the int16_t are in the range
(-255 - 5 * 127)..(255 + 5 * 128).
This commit modifies the checkasm test to only use
values from this range, fixing (undefined) integer overflow
in the test.

The requirement is either 8 or 16 bytes alignment, not 32.
This should help finding bugs in asm implementations.

xHE-AAC relies on the same postfilter mechanism
that Opus uses to improve clarity (albeit with a steeper
deemphasis filter).
The code to apply it is identical, it's still just a
simple IIR low-pass filter. This commit makes it possible
to use alternative constants.
We have test to make sure that certain configurations do print
warnings. However, the normal operation of the muxer within this
test always printed a warning, so those tests to check for
extra warnings didn't essentially guard anything.
The warning that always was printed, "track 1: codec frame size is
not set" was not present in the libav fork where this testcase
originated, it was removed in f234e8a32e6c69d7b63f8627f278be7c2c987f43.
Set the frame size for the audio stream to silence the warning,
and use this frame size in a couple later calculations, and check
that one test configuration doesn't print warnings.
Setting the frame size apparently changes the rounding of a timestamp
in the ismv muxing testcase.

The exclude_guest option only has an effect on x86. Omitting
'exclude_guest' defaults to zero which implies that you can count guest
events should you run one. Some non-x86 kernels just ignore it, while
others (e.g. the Asahi Linux kernels) require the user to explicitly set
the option to 1, i.e. the only behaviour that makes sense when counting
guest events isn't supported.

This is based on a spec at https://aomediacodec.github.io/id3-emsg/,
further based on ISO/IEC 23009-1:2019.
Within libavformat, timed ID3 metadata (already supported by the
mpegts demuxer and muxer) is handled as a separate data AVStream
with codec type AV_CODEC_ID_TIMED_ID3. However, it doesn't
have a corresponding track in the mov file - instead, these events
are written as separate toplevel 'emsg' boxes.

Previously we always assumed that the channels are in native order, even if
they were not. The new channel layout API allows us to signal the proper
channel order, so let's do so.

Note that the config.sh file is left without a shebang, this file is
supposed to be sourced into the current environment.
This commit is purely cosmetic.

Unlike what the old comment suggested, standard ASS has no character
escape mechanism, but a closing curly bracket doesn't even need one.
For manual authored sub files using a full-width variant of an
appropriate font and with scaling and spacing modifiers is a common
workaround.
This is not an option here, but we can still make things much less bad.
Now the desired opening bracket still shows up in libass, and
standard renders will merely display a backslash in its place
instead of stripping the following text like before.
Creating vsynth_lena.yuv needs the FATE suite,
yet several tests in ffmpeg.mak without a dependency
on samples used it as input file. Fix this by using
vsynth1.yuv (which does not have such a dependency)
instead.
Also use vsynth1.yuv in fate-shortest to avoid
the samples dependency in this test, too.
Fixes ticket #10947.

A namespace is unnecessary here given that all these files

The ffprobe-test file is generated via ffmpeg and several filters;
the requirements for them were missing.
Also deduplicate this while just at it.
