mpeg4audio: rename AOT_USAC_NOSBR to AOT_USAC
The issue is that AOT 45 isn't defined anywhere, and looking at the git
blame, it seems to have sprung up through a reordering of the enum,
and adding a hole.

The spec does not define an explicit AOT for SBR and no SBR, and only
uses AOT 42 (previously AOT_USAC_NOSBR), so just rename AOT_USAC to
it and replace its use everywhere.

libavfilter/signature_lookup: fix jaccard distance
Actually, the jaccard distance is defined as D = 1 - intersect / union.
Additionally, the distance value is compared against a constant that
must be between 0 and 1, which is not the case here. Both facts together
has led to the fact, that the function always returned a matching course
signature. To leave the constant intact and to avoid floating point
computation, this commit multiplies with 1 << 16 making the constant
effectively 9000 / (1<<16) =~ 0.14.

Rémi Denis-Courmont 8d117024fe checkasm: disable unaligned access emulation
The OS may silently fix (emulate) unaligned hardware access exceptions.
This is extremely slow and code should be fixed not to rely on unaligned
access on affected hardware. Accordingly this requests that the OS
disable emulation and instead throw Bus error, which will be caught by
checkasm's signal handler.

This has no effects if the hardware supports unaligned access in
hardware, since no exceptions are generated. prctl() will fail safe in
that case.

Zhao Zhili 2a68b2d643 avcodec/mediacodecenc: workaround the alignment requirement only for H.264
There is no bsf for other codecs to modify crop info except H.265.
For H.265, the assumption that FFALIGN(width, 16)xFFALIGN(height, 16)
is the video resolution can be wrong, since the encoder can use CTU
larger than 16x16. In that case, use FFALIGN(width, 16) - width
as crop_right is incorrect. So disable the workaround for H.265 now.

Zhao Zhili 680b3cee1f avcodec/h265_metadata: Add options to set width/height after crop
It's a common usecase to request a video size after crop. Before
this patch, user must know the video size before crop, then set
crop_right/crop_bottom accordingly. Since HEVC can have different
CTU size, it's not easy to get/deduce the video size before crop.
With the new width/height options, there is no such requirement.
