In order to send VP9 tracks with FLV or RTMP, the enhanced RTMP
specification tells that VPCodecConfigurationRecord, a.k.a. vpcC
ISO-BMFF box, must be inserted into a metadata message. However, the
function responsible for generating vpcCs currently returns invalid
boxes, that are lacking the Version and Flag fields, inherited from
FullBox. For some reason, both flags were being added manually in
movenc. This patch fixes the issue.

This makes the test stricter because it is checked that the
MMX registers are not accidentally clobbered.

Only sub_media_pred has an MMXEXT version, so one can use
the version with the stricter check (that checks that
the MMX registers have not been clobbered) for sub_left_predict.

Only the idct_dc and add_residual functions have MMX versions,
so one can use the version with the stricter check (that checks
that the MMX registers have not been clobbered) for all the other
checks.

It is not even clear what these emms_c() are supposed to achieve:
create_filtergraph() (where it may be called) does not call
ASM functions itself; it merely sets some function pointers.
Furthermore, there are no colorspacedsp functions using MMX
(checked by checkasm which does not use declare_new_emms()).
Finally, checking whether to issue emms_c() is overblown anyway.

winbase.h defines IGNORE and is included via bzlib.h when compiling
for Windows. So rename this macro to NOTHING.
Also rename the muxer macro for consistency.

It includes various Windows-specific headers when compiling
for Windows and these sometimes cause issues: E.g. winbase.h
defines IGNORE, which clashes with a macro used in the Matroska
muxer (since 884653ee5b) and demuxer.
This header provides fallback defines for various stuff that is
mostly not used directly by (de)muxers at all:
mkdir, rename, rmdir, unlink, access, poll, pollfd, nfds_t,
closesocket, socklen_t, fstat, stat, lseek, SHUT_(RD|WR|RDWR)
and various POLL* constants.
Ergo fix this issue by not auto-including this header in lots
of places via an inclusion in internal.h and instead include
it everywhere where the above stuff is used (most of these
translation units already included os_support.h).

This is the very last user of any lavc transform code.
This also *corrects* wmavoice decoding, as the previous DCT/DST
transforms were incorrect, bringing it closer to Microsoft's
own wmavoice decoder.
These are in-place transforms, required for DCT-I and DST-I.
Templated as the mod2 variant requires minor modifications, and is
required specifically for DCT-I/DST-I.
The word "monotonous" means "spoken in a monotone" which is not what we
mean here. We mean "monotonic" i.e. nondecreasing.

Adds a fate test for the jpegxl_anim demuxer, that should allow testing
for true positives and false positives for animated jpegxl files. Note
that two of the test cases are not animated, in order to help sort out
false positives.

This simplification reduces codesize.
(It even reduces the size of .rodata here, because
the jump table used by the compiler is bigger than
the actual array.)

When muxing, the AVStreams' side-data is typically set
by the caller before avformat_write_header();
it is not documented to be else. Yet the Matroska muxer
added an AVStereo3D side data if certain metadata
was present:
Since commit 4d686fb721
(adding support for AVStereo3D stream side-data),
the Matroska muxer checked certain stream tags that
contain Matroska's StereoMode and (if they are present)
converted this value into an AVStereo3D struct that
gets attached to the AVStream (reusing a function from
the demuxer). Afterwards the AVStereo3D side data struct
(whether it has just been added by the muxer or not) gets
parsed and converted back into a Matroska StereoMode.
Besides being an API violation this change broke
StereoMode values without a corresponding AVStereo3D
(namely the anaglyph ones).
This commit fixes this: A StereoMode given via tags
is now used-as-is; if no such tag exists and an AVStereo3D
side data exists, it is converted into the corresponding
StereoMode (if possible). This approach also fixes
handling of the anaglyph ones; the changes to the
matroska-stereo_mode are due to this.
The new STEREOMODE_STEREO3D_MAPPING has been put to
good use for this.

It will allow to create tables for easy conversion from AVStereo3D
to stereomode and back again as well as derive the properties
of a given stereomode.
