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:

- ID3v2 a.k.a. "ea3" header is optional.
- Version and flags in ID3v2 header are unspecified.

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.

For some weird reason gcc does not check if the -Wno disabling variants
of warning flags match existing warning flags. Instead it swallows them
silently. That is, unless other warning or error messages are generated,
because then - for some even more bizarre reason - a complaint about the
unknown disable warning flag is issued along with the error or warning
message.

Thus to check for the availability of a warning disabling option, one
needs to check for the enabling variant instead and then add the
disabling variant to CFLAGS.

This is useful to test flags without directly adding them to CFLAGS.

Fix out of array accesses.
