If the time code side data is overridden by the packet level, we also
make sure not to update `out->metadata` to a mismatched timecode.

The signature of these wrappers is more complicated due to a need to
distinguish between "failed allocating side data" and "side data was
already present".

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.
The longest string here takes four bytes, so using an array
of pointers is wasteful even when ignoring the cost of relocations;
the lack of relocations also implies that this array
will now be put into .rodata and not into .data.rel.ro.
Static asserts are used to ensure that all strings are always
properly zero-terminated.

The allocators have been superseded by av_vdpau_bind_context().
The latter have only been added "to allow multiple forks to add
fields to the structure without breaking ABI" [1], but libav
is no more, so this is not needed any longer.

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.

It is no longer used by any hwcontext, as they all allocate
their private data together with their public data and access
it via AVHWFramesContext.hwctx.

This is possible because the lifetime of both coincide.
Besides reducing the number of allocations this also simplifies
access to D3D12VAFramesContext as one no longer has to
go through AVHWFramesInternal.

This is possible because the lifetime of these structures coincide.
It has the advantage of allowing to remove the AVHWDeviceInternal
from the public header; given that AVHWDeviceInternal.priv is no more,
all accesses to it happen in hwcontext.c, so that this commit moves
the joint structure there.
