Forgotten in d1d30edf42.
This fixes standalone compilation of the VC-1 based
decoders when using shared builds (for static builds,
nothing pulls in msmpeg4data.o, yet for shared builds
the default behaviour of linkers is different, leading
to undefined references because msmpeg4data.o relies
on stuff from mpeg4video.o).

It reuses e.g. ff_put_pixels8_l2_8() directly even though
it never initializes a QpelDSPContext.
Fixes standalone compilation of the wmv2 encoder (the decoder
already has a qpeldsp dependency via the h263 decoder).

Before this patch, the implementation of pipe: inputs/outputs would
silently fall back to stdin/stdout for any argument not successfully
parsed by strtol().
This patch introduces an explicit error for any non-numerical arguments,
which should avoid user confusion as in #10977.
New behavior:
$ cat /tmp/video.mkv | ./ffmpeg -i pipe:aa -acodec copy -vcodec copy -f matroska pipe:1 | cat >/tmp/out.mkv
[pipe @ 0x5618c7bcf740] Non-numerical argument "aa" to pipe:
[in#0 @ 0x5618c7bced00] Error opening input: Invalid argument
Error opening input file pipe:aa.
Error opening input files: Invalid argument

There is nothing that forces us to use the same value
as mpegvideo_enc.c, so define our own constant.

This is achieved by using function pointers for AAC SBR functions.
This unfortunately necessitated to use void* in
ff_aac_sbr_apply(_fixed).

This is more in line with how we initialize DSP functions
and avoids tables of function pointers as well as relocations
for these.

This allows to merge it with AACDecDSP.init and remove the latter
(it is called only once anyway); it also allows to make
the fixed/float AACDecDSP and AACDecProc implementations internal
to aacdec_fixed/float.c (which also fixes a violation of our
naming conventions). And it some linker errors when either decoder
is disabled.

ff_aac_sbr_apply() and ff_aac_sbr_apply_fixed() still used
pointers to INTFLOAT which is float or int depending upon
whether USE_FIXED is set or not; in particular, according
to these declarations both functions have the same type.
But that is wrong and given that aacdec.c sets USE_FIXED,
it sees the wrong type for ff_aac_sbr_apply().
This leads to a -Wlto-type-mismatch warning when using lto [1].
Fix this by avoiding INTFLOAT in aacsbr.h (which also means
that aac_defines.h need not be included there any more).

This adds the Linux-specific function call to detect CPU features. Unlike
the more portable auxillary vector, this supports extensions other than
single lettered ones. At this point, FFmpeg already needs this to detect
Zba and Zbb at run-time, and probably will need it for Zvbb in the near
future.
Support will be available in glibc 2.40 onward.
For some error bitstreams, a CTU belongs to two slices/entry points.
If the decoder initializes and submmits the CTU task twice, it may crash the program
or cause it to enter an infinite loop.

sc->data_size may contain the size of a single fragment after probing, and
using it alongside the duration of the entire stream to calculate bitrate
will result in a bogus small value.
