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.

Makes it robust against adding fields before it, which will be useful in
following commits.
Majority of the patch generated by the following Coccinelle script:
@@
typedef AVOption;
identifier arr_name;
initializer list il;
initializer list[8] il1;
expression tail;
@@
AVOption arr_name[] = { il, { il1,
- tail
+ .unit = tail
}, ... };
with some manual changes, as the script:
* has trouble with options defined inside macros
* sometimes does not handle options under an #else branch
* sometimes swallows whitespace
In the mov muxer (in mov_write_video_tag()), bits_per_coded_sample will
be written under certain conditions and is required to be 32 for the
transparency to be honored in QuickTime.
prores_kostya already has this setting but prores_anatoliy and
prores_videotoolbox didn't.
Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;
also avoids relocations.

1. If user don't specify the profile, set it to main10 when pixel
format is 10 bits. Before the patch, videotoolbox output main
profile bitstream with 10 bit input, which can be confusing.
2. Warning when user set profile to main explicitly with 10 bit
input. It works, but not the best choice.
3. Reject main 10 profile with 8 bit input, it doesn't work.

Will be used in the following patch. With hw_config we can get
avctx->hw_frames_ctx, and with avctx->hw_frames_ctx we get
sw_pix_fmt. Otherwise sw_pix_fmt is none. I need sw_pix_fmt
before get the first frame to set hevc encoder profile.

These defines are also used in other contexts than just AVCodecContext
ones, e.g. in libavformat. Furthermore, given that these defines are
public, the AV-prefix is the right one, so deprecate (and not just move)
the FF-macros.

Use CFDictionarySetValue to enable low-latency encoding mode.
Since the key is a type of "EncoderSpecification", instead of
"CompressionProperty".

This can happen when user set the avctx->profile field directly
instead of specify profile via option.

Other than save a few bytes, it also has the benefit to show the
AV_OPT_TYPE_CONST value in help, e.g.,
-profile <int> E..V....... Profile (from 0 to INT_MAX) (default 0)
baseline 66 E..V....... Baseline Profile

Added support for more VideoToolbox encoder options:
- qmin and qmax options are now used
- max_slice_bytes: Max number of bytes per H.264 slice
- max_ref_frames: Limit the number of reference frames
- Disable open GOP when the cgop flag is set
- power_efficient: Enable power-efficient mode

When using low-latency mode, it eliminates frame reordering

It reduces typing: Before this patch, there were 105 codecs
whose long_name-definition exceeded the 80 char line length
limit. Now there are only nine of them.

Adds an option to use constant bitrate instead of average bitrate to the
videotoolbox encoders. This is enabled via -constant_bit_rate true.
macOS 13 is required for this option to work.

and remove FF_CODEC_CAP_INIT_THREADSAFE
All our native codecs are already init-threadsafe
(only wrappers for external libraries and hwaccels
are typically not marked as init-threadsafe yet),
so it is only natural for this to also be the default state.

This is possible, because every given FFCodec has to implement
exactly one of these. Doing so decreases sizeof(FFCodec) and
therefore decreases the size of the binary.
Notice that in case of position-independent code the decrease
is in .data.rel.ro, so that this translates to decreased
memory consumption.

Up until now, codec.h contains both public and private parts
of AVCodec. This exposes the internals of AVCodec to users
and leads them into the temptation of actually using them
and forces us to forward-declare structures and types that
users can't use at all.
This commit changes this by adding a new structure FFCodec to
codec_internal.h that extends AVCodec, i.e. contains the public
AVCodec as first member; the private fields of AVCodec are moved
to this structure, leaving codec.h clean.

Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault.
This reduces the amount of files that have to include internal.h
(which comes with quite a lot of indirect inclusions), as e.g.
most encoders don't need it. It is furthemore in preparation
for moving the private part of AVCodec out of the public codec.h.

On some encoders, this defaults to true, which can result in encode speed
being _limited_ to only slightly above realtime (as a power-saving measure),
so we need a way to disable it.
In function vtenc_populate_extradata(), there is a manually created
pixel buffer that has not been released. So we should use CVPixelBufferRelease
to release this pixel buffer at the end, otherwise will cause a memory leak.
