Every function in rgb2rgb_template.c is only compiled exactly
once; there is no overlap at all between the MMXEXT and the
SSE2 functions, so detemplatize it.

The SSE2 and AVX versions of deinterleaveBytes are external ASM.
Move them out of the inline ASM template.

The MMXEXT versions of the rgb2rgb functions tested here
always emit emms on their own. Therefore one can use
a stricter test to ensure that it stays that way.

It is unnecessary to first pad to 32bits; the memset later
will pad everything will with zeroes anyway.

This is the VVC version of 8b5d155301.
(Hint: This ensures that the order of NALU arrays is OPI-VPS-SPS-PPS-
Prefix-SEI-Suffix-SEI, regardless of the order in the original
extradata. I hope this is right.)

There is no benefit in using it: The fast path of copying
is not taken because of misalignment; furthermore we are
only dealing with a few byte here anyway, so simply copy
the bytes manually, avoiding the dependency on bitstream.c
in lavf (which also contains a function that is completely
unused in lavf).

If any of these files (say A) would be changed in such a way
that A acquires a new dependency on another file B, building B
would need to be added to all the rules that lead to A being built.
Yet currently the rules for several files are spread over
the lavc Makefile and the Makefile of the lavc/hevc subdir, making
it more likely to be forgotten. So move the rules for these files
to the lavc/Makefile.

Add xpu device support to libtorch backend.
To enable xpu support you need to add
"-Wl,--no-as-needed -lintel-ext-pt-gpu -Wl,--as-needed" to
"--extra-libs" when configure ffmpeg.

Require that there is a valid layout with a valid number of channels
before accepting nb_elems.
The value is required when flushing.
Thanks to kasper93 for figuring it out.
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.
