0eb399ac39 avcodec: Constify ThreadFrames if possible
This is possible now that ff_thread_await_progress() accepts
a const ThreadFrame*.

136ada2fc3 avcodec/hevc_mvs: Pass HEVCLocalContext when slice-threading
The HEVC decoder has both HEVCContext and HEVCLocalContext
structures. The latter is supposed to be the structure
containing the per-slicethread state.

Yet that is not how it is handled in practice: Each HEVCLocalContext
has a unique HEVCContext allocated for it and each of these
coincides except in exactly one field: The corresponding
HEVCLocalContext. This makes it possible to pass the HEVCContext
everywhere where logically a HEVCLocalContext should be used.

This commit stops doing this for lavc/hevc_mvs.c; it also constifies
everything that is possible in order to ensure that no slice thread
accidentally modifies the main HEVCContext state.

b3551b6072 avcodec/thread: Move ff_thread_(await|report)_progress to new header
This is in preparation for further commits that will stop
using ThreadFrame for frame-threaded codecs that don't use
ff_thread_(await|report)_progress(); the API for those codecs
having inter-frame depdendencies will live in threadframe.h.
