From the documentation of GNU awk [1]:
"In most awk implementations, including gawk, rand() starts generating
numbers from the same starting number, or seed, each time you run awk.45
Thus, a program generates the same results each time you run it. The
numbers are random within one awk run but predictable from run to run.
This is convenient for debugging, but if you want a program to do
different things each time it is used, you must change the seed to a
value that is different in each run. To do this, use srand()."
This commit does exactly this.

And remove the AVOID_PROBING flag, given it's the last av1 decoder to be tested
either way.
This fixes a regression introduced in 1652f2492f,
where even if forcing the native av1 decoder, if another decoder was present,
like libdav1d or libaom-av1, they'd be used for probing and some fate tests
would have different results.

Useful for discovering bugs that depend on a specific thread count.
Use like THREADS=randomX for a random thread count from 1 to X, with
X=16 when not specified. Note that the thread count is different for
every test.
Since this is an external encoder not under our control, we cannot test
the encoded output exactly as is done for internal encoders. We can
still test however that the output is decodable and produces the
expected number of frames with expected dimensions, pixel formats, and
timestamps.
The output file (even the filesize) of the recently added
EXR tests depends on the endianness; therefore checksums
of these files must not be part of the ref file. Therefore
this commit adds an option (unused for now) to disable these
checksums on a per-test basis.
In order to avoid having to check twice, the checksum and
the filesize info are moved to immediately follow one another;
this results into updates to the ref files of all lavf-image tests.

enc_dec() performs two ffmpeg runs - the first one encoding a source
file into a specified output format, the second one decoding previously
encoded file.
The arguments to this function currently have confusing names - e.g.
dec_opt contains _output_ (i.e. encoding) options for the second
(decoding) ffmpeg invocation. It is also possible to supply _input_
(i.e. decoding) options for the second ffmpeg run, but the argument
is currently unnamed and referred to by number.
Add an _in/_out suffix to argument names to make it clear what they are
used for. Give a name to input options for the decoding ffmpeg run.
The temporary fate-lavf files can easily be removed
if they are not needed as inputs for other tests (mainly
fate-seek-tests). This commit implements this.
The size of the remaining files decreases from 260890083B
to 79481793B.

Extend the ordinary mechanism to signal KEEP for this.
This also allows to remove the keep-parameter from enc_dec,
transcode and stream_remux, so that several empty parameters
'""' could be removed.

These CRC-only files (the output of the CRC-muxer) are only used once,
so they need not be preserved. Furthermore, errors from ffmpeg (used
for creating the CRC) are no longer ignored with this patch.

The output of this test is just a file containing the positions
of peaks; it is not a wave file and trying to demux it just
returns AVERROR_INVALIDDATA; said error has just been ignored
as the return value from do_avconv_crc is the return value from echo.

On empty input the awk script was always successful which caused the
filter-refcmp tests to always succeed.
Also fix the command lines for refcmp_metadata compare function because it
needs auto conversion filters, and update reference of test
filter-refcmp-psnr-rgb because it was missed in
a7fc78c1a6 but was never noticed due to the
original issue...

Calculate Spatial Info (SI) and Temporal Info (TI) scores for a video, as defined
in ITU-T P.910: Subjective video quality assessment methods for multimedia
applications.
This allows nicer tests by having a greater range of inputs available
(without requiring adding further samples to the fate-suite).

The md5 test up until now ignored errors from ffmpeg (the cli) and just
md5'ed whatever ffmpeg has output; while testing scenarios in which
ffmpeg fails has its merits, errors should not be overlooked by default;
doing so also reduces the effectiveness of sanitizers as errors from
them are ignored. This has happened with a memleak in the AV1 decoder.

Explicitly insert the scale or aresample filter where it would
have been inserted by the negotiation.
Re-enable conversions if it cannot be done easily.
If a conversion is needed in a test, we want to know about it.
If the negotiation changes and makes new conversion necessary,
we want to know about it even more.

This is primarily intended to test that muxers correctly write chapters
or metadata; but given that it does this by having our demuxers read the
generated files, it also tests demuxers. And of course it may prove
useful for encoders, too.
