37a749012a lavc: rework handling of refcounted_frames=0
Use only proper AVFrame API (no assigning of whole frames, since that
hardcodes sizeof(AVFrame) into lavc).

Make a copy of the side data, so the caller can use av_frame_unref/free
on non-refcounted frames, eliminating the need for
avcodec_get_frame_defaults()/avcodec_free_frame().

08303d7741 hwaccel: Simplify ff_find_hwaccel

da6506c607 lavc: move AVCodecContext.pkt to AVCodecInternal
It's a private field, not meant to be accessed from outside lavc.

38ecc3702d pthread: store thread contexts in AVCodecInternal instead of AVCodecContext
It's a private field, it should not be visible to callers.

Deprecate AVCodecContext.thread_opaque

7644f5a807 lavc: replace avcodec_set_dimensions with ff_set_dimensions
avcodec_set_dimensions() is supposed to be an internal utility function,
there is no reason whatsoever for it to be public. Therefore deprecate
it.

Also move the declaration to internal.h, and add restrict qualifiers
to the declaration (as in the implementation).

192f1984b1 lavc: limit maximum number of channels to 63
This is the most that can be represented with the current channel layout
system. This limit should be raised/removed when a better system is
implemented.

Any performance gain from this is negligible and not worth the extra

b2c75b6e63 avcodec: Add avcodec_encode_audio2() as replacement for avcodec_encode_audio()
This allows audio encoders to optionally take an AVFrame as input and write
encoded output to an AVPacket.

This also adds AVCodec.encode2() which will also be usable by video and
subtitle encoders once support is implemented in the public functions.

8400b126ac avcodec: deprecate AVFrame.age
This was intended as an optimisation for skipped blocks in MPEG2
P-frames and never used elsewhere.  Removing this "optimisation"
speeds up MPEG2 decoding by 1-2% (ARM Cortex-A9).

f3a29b750a avcodec: move some AVCodecContext fields to an internal struct.
A new field, AVCodecContext.internal is used to hold a new struct
AVCodecInternal, which has private fields that are not codec-specific and are
used by general libavcodec functions.

Moved internal_buffer, internal_buffer_count, and is_copy.
