wingdi.h defines its own PASSTHROUGH and it is included implicitly
by the VC-1 parser (which is mpegvideo-based and therefore includes
a lot of stuff).

AVCodecParser has several fields which are not really meant
to be accessed by users, but it has no public-private
demarkation line, so these fields are technically public
and can therefore not simply be made private like
20f9727018 did for AVCodec.*
This commit therefore deprecates these fields and
schedules them to become private. All parsers have already
been switched to FFCodecParser, which (for now) is a union
of AVCodecParser and an unnamed clone of AVCodecParser
(new fields can be added at the end of this clone).
*: This is also the reason why split has never been removed despite
not being set for several years now.

The current code relies on AV_CODEC_ID_NONE being zero, so that
unused codec ids are set to their proper value. This commit adds
a macro to set unset ids to AV_CODEC_ID_NONE.
(The actual rationale for this macro is to simplify
the transition to making the private fields that are
currently public in avcodec.h really private.)

It only contains declarations for some auxiliary functions for parsing
that parsers that only work with complete packets don't need.

The graph string is either freed or attached to the filtergraph, so it's best to
not leave a dangling pointer with the caller.

The decode API can handle outputting delayed frames without relying on the
parser splitting off the ENDOFSEQ marker.

These functions are currently always called with height either
being equal to the block size or block size+1. height is
a compile-time constant at every callsite. This makes it possible
to split this function into two to avoid the check inside
the function for whether height is odd or even.
The corresponding avg function is only used with height == block size,
so that it does not have a height parameter at all. Removing the
parameter from the put_l2 functions as well therefore simplifies
the C code.
The new functions increase the size of .text from qpel{dsp}.o
by 32B here, yet they save 464B of C code here.

SSSE3 is already quite old (introduced 2006 for Intel, 2011 for AMD),
so that the overwhelming majority of our users (particularly those
that actually update their FFmpeg) will be using the SSSE3 versions.
This commit therefore removes the MMX(EXT) functions overridden
by them (which don't abide by the ABI) to get closer to a removal
of emms_c.

The only difference between it and the H.264/VC-1 versions is the
bias constant which depends on the shift parameters for RV40.
This value ends up in a register and therefore one can reuse
the H.264 code by setting the registers for RV40 and then jumping
into the relevant H.264 function, making the four new functions
cheap (just 256 bytes in total). This approach uses one jump more
for the no-filter case and one jump less in the one-dimensional
case than an approach using separate functions.

In the QTFF documentation for udta/"user data atoms", "name" is a
valid entry for "name of object" however it is currently skipped
leading to some missing metadata when copying for some files. This
isn't classified the same as "(C)nam" which is "Title of content"
so they aren't necessarily the same.
For the purpose of merging streams in a stream group, a filtergraph can't be
created once we know it will be used. Therefore, allow filtergraphs to be
removed from the scheduler after being added.

Several formats are being designed where more than one independent video or
audio stream within a container are part of what should be a single combined
output. This is the case for HEIF (Defining a grid where the decoded output
of several separate video streams are to be placed to generate a single output
image) and IAMF (Defining audio streams where channels are present in separate
coded stream).
AVStreamGroup was designed and implemented in libavformat to convey this
information, but the actual merging is left to the caller.
This change allows the FFmpeg CLI to take said information, parse it, and
create filtergraphs to merge the streams, making the combined output be usable
automatically further in the process.
