Rename it to AVDictionary, since it will be used as such.  Tags
documentation and metadata conversion API is lavf-specific, so remains
there.

Subject: [PATCH 07/10] swscale: move two macros that are only used once into
 caller.

This way, they look like regular code, which is easier to
understand.

Subject: [PATCH 08/10] swscale: fix types of assembly arguments.

This prevents the following compiler warnings: "warning:
initialization from incompatible pointer type". Since the
variables are only ever used in inline assembly, their type
is actually irrelevant (so the part where it was wrong did
not invoke any buggy behaviour).
