According to the VVC specification (section 8.5.1), the maximum width/height of a subblock passed for DMVR SAD is 16. This along with previous constraint requiring width * height >= 128 means that 8x16, 16x8, and 16x16 are the only allowed sizes.
This changes check_vvc_sad() to only test and benchmark those sizes.
Several files already had standard license header (namely
2-clause BSD files), yet due to the 80 char line length limit,
they were not treated as such by source-check.sh (which
fate-source uses). Therefore relax the BSD check.

VVC does not have MMX code at all, so one can use the stricter
declare_func to also check that the MMX state has not been clobbered
with (which would be an ABI violation).

The loop filters can write before the pointer given to them;
the actual test invocations correctly used an offset, while
the benchmark calls were lacking an offset. Therefore, when
running with benchmarking, these tests could have spurious
failures.

Some timers on certain device and test combinations can produce noisy
results, affecting the reliability of performance measurements. One
notable example of this is the Canaan K230 RISC-V development board.
An option to adjust the number of samples by an exponent (--runs) has
been added, allowing developers to increase the sample count for more
reliable results.

Don't benchmark every single combination of widths and heights;
only benchmark cases which are squares (like in vvc_mc.c).
Contrary to vvc_mc, which increases sizes by doubling dimensions,
vvc_alf tests all sizes in increments of 4. Limit benchmarking to
the cases which are powers of two.
This reduces the number of benchmarked cases from 3072 down to 18.
This commit is the analog of 3f11eac757
for decoding: It sets the AV_FRAME_FLAG_KEY and (for video decoders)
also pict_type to AV_PICTURE_TYPE_I. It furthermore stops setting
audio frames as always being key frames -- it is wrong for e.g.
TrueHD/MLP. The latter also affects TAK and DFPWM.
The change already improves output for several decoders where
it has been forgotten to set e.g. pict_type like speedhq, wnv1
or tiff. The latter is the reason for the change to the exif-image-tiff
FATE test reference file.

Fixes "signed integer overflow: [varies] * 104858 cannot be represented in type 'int'" errors

The only multiplicators used in scalarproduct_and_madd_*
are -1, 0 and +1. Yet it is of type int and the checkasm
test uses the complete range of int for it, leading to overflows
that don't happen for actual users.
Fix this by using a more reasonable range for mul: Given
that it is used in v1[i] += v3[i] * mul with v1 being
a 16bit integer, it makes no sense to use values for mul
that don't fit into 16bit.

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.
