And rename it to ff_encode_add_stats_side_data() and move its
declaration to encode.h. Also constify the error pointee.

There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

Instead, use forward declarations; and in order not to affect
any user include these headers for them, but not internally.
This has the advantage of removing implicit inclusions of these
headers from almost all files providing codecs.

Mention encoder name in the message to emphasize that the value in
question is not supported by this specific encoder, not necessarily by
libavcodec in general.
Print a list of values supported by the encoder.
The goal is to distinguish between APIs provided by the generic layer to
individual codecs and APIs internal to the generic layer.
Start by moving ff_{decode,encode}_receive_frame() and
ff_{decode,encode}_preinit() into this new header, as those functions
are called from generic code and should not be visible to individual
codecs.
For encoding, this field is entirely redundant with
AVCodecContext.framerate.
For decoding, this field is entirely redundant with
AV_CODEC_PROP_FIELDS.
Current code prefers deprecated AVFrame.pkt_duration over its
replacement AVFrame.duration whenever the former is set and not equal to
the latter. However, duration will only be actually used when the
caller sets the AV_CODEC_FLAG_FRAME_DURATION flag, which was added
_after_ AVFrame.duration.
This implies that any caller aware of AV_CODEC_FLAG_FRAME_DURATION is
also aware of AVFrame.duration. pkt_duration should then never be used.
Frame counters can overflow relatively easily (INT_MAX number of frames is
slightly more than 1 year for 60 fps content), so make sure we use 64 bit
values for them.
Also deprecate the old 32 bit frame_number attribute.

This is intended to be a more convenient replacement for
reordered_opaque.
Add support for it in the two encoders that offer
AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE: libx264 and libx265. Other
encoders will be supported in future commits.
Some encoders (ffv1, flac, adx) are marked with AV_CODEC_CAP_DELAY onky
in order to be flushed at the end, otherwise they behave as no-delay
encoders.
Add a capability to mark these encoders. Use it for setting pts
generically.
Now that it is ensured that the old and new channel count/layout
values coincide if the old ones are set, the consistency of the
AVChannelLayout (which is checked before we reach this point)
implies the consistency of the old values, making these checks
here dead code. So remove them.

In particular, check the provided channel layout for encoders
without AVCodec.ch_layouts set. This fixes an infinite loop
in the WavPack encoder (and maybe other issues in other encoders
as well) in case the channel count is zero.

The wrapper for the legacy channel layout API already sets
AVCodecContext.channels based upon AVCodecContext.channel_layout
if the latter is set while the former is unset.
