Also remove a variable that is only used in this commented-out
codeblock. This fixes a -Wunused-variable warning.

This avoids one redundant load per row; pix3 from the previous
iteration can be used as pix2 in the next one.
Before: Cortex A53 A72 A73
pix_abs_0_2_neon: 138.0 59.7 48.0
After:
pix_abs_0_2_neon: 109.7 50.2 39.5

Fixes the j2k-dwt FATE-test; also fixes#9945.
(I don't know whether the multiplication can overflow.)

Possible since 48ac225db2.
Furthermore, the current code would not work on mips
in case ff_lsp2polyf() were used outside of lsp.c,
because it is not compiled on mips since commit
3827a86eac at all;
instead it is overridden with a static av_always_inline
function which only works for the callers in lsp.c.

Will avoid a forward declaration lateron.
Also adapt the function to modern style while at it.

They will be mistaken for the sentinel of the arrays
they are in, thereby hiding the 6.1, 7.1 and 22.2 layouts.
(This doesn't really matter, as these arrays are informational
only for decoders.)

AVCodec.channel_layouts is deprecated and Clang (unlike GCC)
warns when setting this field in a codec definition.
Fortunately, Clang (unlike GCC) allows to use
FF_DISABLE_DEPRECATION_WARNINGS inside a definition (of an FFCodec),
so that one can create simple macros to set AVCodec.channel_layouts
that also suppress deprecation warnings for Clang.
(Notice that some of the codec definitions were already
inside FF_DISABLE/ENABLE_DEPRECATION_WARNINGS (that were not
guarded by FF_API_OLD_CHANNEL_LAYOUT); these have been removed.
Also notice that setting AVCodec.channel_layouts was not guarded
by FF_API_OLD_CHANNEL_LAYOUT either, so testing disabling it
it without removing all the codeblocks would not have worked.)

Pointers to void can be converted to any pointer to incomplete or
object type and back; but they are nevertheless not completely generic
pointers: There is no provision in the C standard that guarantees their
convertibility with function pointers. C90 lacks a generic function
pointer, C99 made every function pointer a generic function pointer and
still disallows the convertibility with void *. Both GCC as well as
Clang warn about this when using -pedantic.
Therefore use unions to avoid these conversions.

Don't place it as doxy specific for the order field, and generalize it both to
also cover already defined orders and to not make it seem like the user is
required to handle a layout they don't fully support or understand.

av_display_rotation_get will return NAN when the display matrix is invalid,
which would end up printing NAN as an integer in the rotation field. This
is poor for multiple reasons:
* Users of ffprobe have no way of discerning "valid but ugly rotation from
display matrix" from "invalid display matrix".
* It can have unintended consequences on some platforms, such as Linux x86_64,
where NAN is equal to INT64_MIN, which, for example, when printed as JSON,
which uses floating point for all numbers, can end up as invalid JSON or wit
a number that cannot be reserialized as an integer at all.
Since NAN is av_display_rotation_get's error case, just print 0 (no rotation)
when that happens.

This starts with one-time initialisation of the 26 constant factors
like 08edacc248. That is done with
the scalar instruction set. While the formula can readily be vectored,
the gains would (probably) be more than lost in transfering the results
back to FP registers (or suitably reshuffling them into vector
registers).
Note that the main loop could likely be scheduled sligthly better by
expanding the filter macro and interleaving loads with arithmetic.
It is not clear yet if that would be relevant for vector processing (as
opposed to traditional SIMD).
We could also use fewer vectors, but there is not much point in sparing
them (they are *all* callee-clobbered).
This uses the following vectorisation:
for (i = 0; i < blocksize; i++) {
ang[i] = mag[i] - copysignf(fmaxf(ang[i], 0.f), mag[i]);
mag[i] = mag[i] - copysignf(fminf(ang[i], 0.f), mag[i]);
}
