Convert scoped_ptr_malloc -> scoped_ptr, part 5.

Convert scoped_ptr_malloc -> scoped_ptr, part 5.

scoped_ptr_malloc is deprecated; let's get rid of it.

This takes care of the remaining conversions in media/. scoped_ptr requires a
declaration of the deleter, unlike scoped_ptr_malloc, so declarations (minus the
definitions) are in (the new) media/ffmpeg/ffmpeg_deleters.h. (The inline
definitions remain in ffmpeg_common.h.)

Friendly ping now that you're back (and presumably buried in email). (No rush.)
