eatgv: use fixed-width types where appropriate.
mdec: merge mdec_common_init() into decode_init().

There is no point in keeping those two functions separate.
mdec: cosmetics, reformat
mdec: return meaningful error codes.
mimic: remove a pointless cast.
rawdec: use AVPALETTE_SIZE instead of magic constants.
mvi: set framerate

This container does not store timestamps and thus supports CFR only.
pthread: make ff_thread_release_buffer idempotent.

I.e. don't do anything on already released frames.
utvideoenc/v410enc: do not set AVFrame.reference.

That field will be deprecated.
mpegvideo: remove some unused variables from Picture.
h264: remove obsolete comment.
vf_delogo: fix an uninitialized read.
