Common utility function that can be used by all codecs to select the
right (any valid) film grain parameter set. In particular, this is
useful for AFGS1, which has support for multiple parameters.
However, it also performs parameter validation for H274.
This is needed for AV1 film grain as well, when using AFGS1 streams.
Also add extra width/height and subsampling information, which AFGS1
cares about, as part of the same API bump. (And in principle, H274
should also expose this information, since it is needed downstream to
correctly adjust the chroma grain frequency to the subsampling ratio)
Deprecate the equivalent H274-exclusive fields. To avoid breaking ABI,
add the new fields after the union; but with enough of a paper trail to
hopefully re-order them on the next bump.
Also use sizeof of the proper type, namely sizeof(**sd)
and not sizeof(*sd).

av_frame_side_data_get() has a const AVFrameSideData * const *sd
parameter; so calling it with an AVFramesSideData **sd like
AVCodecContext.decoded_side_data (or with a AVFramesSideData * const
*sd) is safe, but the conversion is not performed automatically
in C. All users of this function therefore resort to a cast.
This commit changes this: av_frame_side_data_get() is renamed
to av_frame_side_data_get_c(); furthermore, a static inline
wrapper for it name av_frame_side_data_get() is added
that accepts an AVFramesSideData * const * and converts this
to const AVFramesSideData * const * in a Wcast-qual safe way.
This also allows to remove the casts from the current users.

At least on latest Win 11 and Visual Studio 2022, that DLL does not
exist anymore and can't be installed via any of the usual means.
However, debugging works just fine regardless, so this check makes
debugging impossible.
D3D11CreateDevice will fail anyway if debugging is not supported, so
let's rely on that instead.
These strings are so short (longest takes 11B) that using
pointers is wasteful. Avoiding them also moves hashdesc
into .rodata (from .data.rel.ro).

and make sure we do not leak a channel map on error.

Also make use of the av_channel_from_string() function to determine the channel
id. This fixes some parse issues in av_channel_layout_from_string().

We lacked tests which supposed to fail, and there are some which should fail
but right now it does not. This will be fixed in a later commit.

Deduplicates a lot of code.
Some minor differences (mostly white space and inconsistent use of quotes) are
expected in the fate tests, there was no point aiming for exactly the same
formatting.

All versions of MSVC that support C11 (namely >= v19.27)
also support the restrict keyword, therefore av_restrict
is no longer necessary since 75697836b1.

Native access is from the code that declared the options, foreign access
is from code that is using the options. Forbid foreign access to
AVOption.offset/default_val, for which there is no good reason, and
which should allow us more freedom in extending their semantics in a
compatible way.
Replace the opt_size() function, currently only called from
av_opt_copy(), with
* a constant array of element sizes
* a function that signals whether an option type is POD (i.e.
memcpyable) or not
Will be useful in following commits.
This is possible because the lifetime of these structures coincide.
It has the advantage of allowing to remove AVHWFramesInternal
from the public header; given that AVHWFramesInternal.priv is no more,
most accesses to AVHWFramesInternal are no more; indeed, the only
field accessed of it outside of hwcontext.c is the internal frame pool,
making this commit very simple.
