Once upon a time, 413abbe164
added versions of some put_no_rnd_pixels functions for use
in VP3 and Theora (with an explicit check so that they are
only used for VP3 and Theora). When this was moved to hpeldsp
(from dsputil) in 3ced55d51c,
the check was replaced by a check for the bitexact flag
(and a CONFIG_VP3_DECODER compile-time check), so that
these functions were now used for other codecs as well.
Later commit 1dfc3cf89d
split off the "VP3-specific bits into a separate file",
yet these bits were not really VP3-specific bits at all
any more. (The error was repeated in commit
0a39c9ac0bfd7345fe676b4e2707d9cec3cbb553.) This commit
has not been reverted, because this would make future
changes from Libav (from where it originated) harder,
yet Libav is no more, so this commit effectively reverts
1dfc3cf89d.

Makes the output of the native decoder consistent with external decoders like
libdav1d with fate-enhanced-flv-av1.

This reverts commit eb88ccb92e.
AVCodecContext fields are the proper place for a decoder to export such values.
This change is in preparation for the following commits.
add option named rtmp_enhanced_codec,
it would support hvc1,av01,vp09 now,
the fourcc is using Array of strings.

Fixes the test when the non-bitexact MMXEXT versions of
the hpeldsp functions are used.

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

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.
