2b46ae6407 avcodec/codec_internal: Remove FF_CODEC_CAP_ALLOCATE_PROGRESS 
Before commit f025b8e110,
every frame-threaded decoder used ThreadFrames, even when
they did not have any inter-frame dependencies at all.
In order to distinguish those decoders that need the AVBuffer
for progress communication from those that do not (to avoid
the allocation for the latter), the former decoders were marked
with the FF_CODEC_CAP_ALLOCATE_PROGRESS internal codec cap.

Yet distinguishing these two can be done in a more natural way:
Don't use ThreadFrames when not needed and split ff_thread_get_buffer()
into a core function that calls the user's get_buffer2 callback
and a wrapper around it that also allocates the progress AVBuffer.
This has been done in 02220b88fc
and since that commit the ALLOCATE_PROGRESS cap was nearly redundant.

The only exception was WebP and VP8. WebP can contain VP8
and uses the VP8 decoder directly (i.e. they share the same
AVCodecContext). Both decoders are frame-threaded and VP8
has inter-frame dependencies (in general, not in valid WebP)
and therefore the ALLOCATE_PROGRESS cap. In order to avoid
allocating progress in case of a frame-threaded WebP decoder
the cap and the check for the cap has been kept in place.

Yet now the VP8 decoder has been switched to use ProgressFrames
and therefore there is just no reason any more for this check
and the cap. This commit therefore removes both.

Also change the value of FF_CODEC_CAP_USES_PROGRESSFRAMES
to leave no gaps.

315c956cbd avcodec/pthread_frame: Remove ff_thread_release_buffer() 
It is unnecessary since the removal of non-thread-safe callbacks
in e0786a8eeb. Since then, the
AVCodecContext has only been used as logcontext.

Removing ff_thread_release_buffer() allowed to remove AVCodecContext*
parameters from several other functions (not only unref functions,
but also e.g. ff_h264_ref_picture() which calls ff_h264_unref_picture()
on error).

a83098ab03 avcodec: deprecate thread_safe_callbacks 
They add considerable complexity to frame-threading implementation,
which includes an unavoidably leaking error path, while the advantages
of this option to the users are highly dubious.

It should be always possible and desirable for the callers to make their
get_buffer2() implementation thread-safe, so deprecate this option.

1f4cf92cfb pthread_frame: merge the functionality for normal decoder init and init_thread_copy 
The current design, where
- proper init is called for the first per-thread context
- first thread's private data is copied into private data for all the
  other threads
- a "fixup" function is called for all the other threads to e.g.
  allocate dynamically allocated data
is very fragile and hard to follow, so it is abandoned. Instead, the
same init function is used to init each per-thread context. Where
necessary, AVCodecInternal.is_copy can be used to differentiate between
the first thread and the other ones (e.g. for decoding the extradata
just once).

665e5b0fba lavc: replace AVCodecInternal.allocate_progress with an internal cap 
This is a constant codec property, so a capability flag is more appropriate.
