0a6b1a9f21 Replace int_fast integer types with their sized standard posix counterparts. 
The _fast integer types provide no realworld benefits, but may introduce
portability issues and are just plain ugly.

d36beb3f69 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. 
None of these symbols should be accessed directly, so declare them as
hidden.

Previously it was releasing the buffer which was returned to the user,
which was resulting in a crash in case of direct rendering.
