fc706276c0 lavu/opt: distinguish between native and foreign access for AVOption fields 
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.

ec1b6e0cd4 avcodec/ccaption_dec: Avoid relocations for strings 
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.

c9f5cea9cc avcodec/vdpau: Deprecate redundant allocators and getter/setter 
The allocators have been superseded by av_vdpau_bind_context().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.
