* qatar/master: crypto: Use av_freep instead of av_free lavf: don't try to free private options if priv_data is NULL. swscale: fix types of assembly arguments. swscale: move two macros that are only used once into caller. swscale: remove unused function. options: Add missing braces around struct initializer. mov: Remove leftover crufty debug statement with references to a local file. dvbsubdec: Fix compilation of debug code. Remove all uses of now deprecated metadata functions. Move metadata API from lavf to lavu.
