This allows the usage of codecs in builds that have a parser but no decoders
for remuxing scenarios with raw sources.

Also remove the _minus8 part of the name to be in line with the rest of the
decoder, and fix the storage type for pps_palette_predictor_initializer,
to support hbd values.

Will remove native backend, so change the default backend in filters,
and also remove the python scripts which generate native model file.

Native backend will be removed in following commits, so change the
dnn interface and modify the error message in it first.

Not doing so is an obvious oversight - the ICC profile is tied to the
original colorspace, so if we change it, we should definitely strip this
information.
We should probably also have an extra option to control whether the ICC
profile should be stripped, ignored, or applied, but for now this fixes
an existing bug.
Some testing revealed this to be a very efficient and reliable method of
ingesting GPU frames into libplacebo, so it's a good idea to give as an
example.
This example being first is now misleading because round-tripping
through hwdownload/hwupload is neither required nor recommended. Also,
the comment about avoiding format conversion is unnecessary because
`libplacebo` will now inherit the input frame format by default.
This was a bug/mistake in dae3679a9b.
use_mfra_for by defintion only has an effect on fragmented MP4 files,
making the check not only redundant, but also broken if a user used
the option globally (i.e. set on non-fragmented MP4s).

Also make duration check for mvhd more consistent with the others, write
version 1 of mvhd if duration is at least INT32_MAX instead of UINT32_MAX.

Commit 23eeffcd48 added a hack to support invalid
files where the creation date was encoded as a classic unix timestamp. Let's
reduce the scope of the hack by only applying it to version 0 mdhd/mvhd atoms.
Also warn the user of such possibly broken files.

Support pixel formats 0x11412100, 0x11311100, and 0x41211100, and add
logic to perform 4x horizontal upsampling. This should fix various JPEG
files found in Ticket #8930.
