Only include it if it is needed, namely if __MMX__ is undefined.

X86 is currently the only arch where lavu/cpu.h is basically
automatically included (for internal development): #if ARCH_X86
is true, lavu/internal.h (which is basically included everywhere)
includes lavu/x86/emms.h which can mask missing inclusions
of lavu/cpu.h if the developer works on x86/x64. This has happened
in 8e825ec3 and also earlier
(see 6d236588).
By including said header only if necessary ordinary developer machines
will behave like non-x86 arches, so that missing inclusions of cpu.h
won't go unnoticed any more.

Fixes bitexact decoding with high bit depth samples.

Analyzed by Paul B Mahol <onemda@gmail.com>.

Fixes OOM in #9081.

The IMF demuxer does not set the DTS and PTS of packets accurately in all
scenarios. Moreover, audio packets are not trimmed when they exceed the
duration of the underlying resource.

imf-cpl-with-repeat FATE ref file is regenerated.

Addresses https://trac.ffmpeg.org/ticket/9611

IMF CPLs can reference thousands of files, which can result in system limits
for the number of open files to be exceeded. The following patch opens and
closes files as needed.

Until now, in some cases produced output would be wrong.

Trying to be clever about determining between interface version 8
and 8.1 ended up with pre-8.1 versions of AviSynth+ segfaulting.

The amount of time between interface version 8.1 and 9 is small,
so just restrict the frameprop awareness to version 9 and call it
a day.

This automatically makes the remaining mpegvideo-decoders
(namely msmpeg4v[1-3], mss2, VC-1, VC-1 Image, WMV-[1-3]
and WMV-3 Image) init-threadsafe.
These were the last native codecs that were not init-threadsafe;
only wrappers for external libraries and for hardware accelerations
are now not init-threadsafe.

Since the av_malloc() may fail and return NULL pointer,
it is needed that the 's->edge_emu_buffer' should be checked
whether the new allocation is success.
