This reduces global state and the amount of globally visible tables.

It is always called by passing fields from an AVCodecContext.

AVI does not really support vfr properly, only by padding with null
packets.

Also remove array element numbering comments.

The macros forbidding the system functions no longer exist, obviating
the need for the #undefs.

As another example of bizarre compiler behavior clang groks the
-Wmaybe-uninitialized option, but not -Wno-maybe-uninitialized
and spews a warning for every file that gets compiled.

The function is used in a block of code that is deprecated anyway.

Imporoves detection of some files in the wild:

Previously the profile would not be set if the bitstream needs
to be decoded to know the profile.

It's a private field, not meant to be accessed from outside lavc.

It's a private field, it should not be visible to callers.

Deprecate AVCodecContext.thread_opaque

This should prevent confusion with frame threading.

This makes sure that these branches are eliminated properly
with clang with optimizations disabled.

Before, it just returned width/height. Correct is width/height*sar.

That way it is consistent with DAR as in probe output and setdar.
