Subject: [PATCH 1/2] avcodec/parser_internal: Rename PASSTHROUGH macro to
 avoid name conflict

wingdi.h defines its own PASSTHROUGH and it is included implicitly
by the VC-1 parser (which is mpegvideo-based and therefore includes
a lot of stuff).

Subject: [PATCH 2/2] avcodec/parsers: Silence deprecation warnings

Slipped through because Clang (in contrast to GCC) does not warn about
this.
