ecebf9c693 avcodec/avcodec: add AVCodecContext.alpha_mode
Following in the footsteps of the previous commit, this commit adds the
new fields to AVCodecContext so we can start properly setting it on codecs,
as well as limiting the list of supported options to detect a format mismatch
during encode.

This commit also sets up the necessary infrastructure to start using the
newly added field in all codecs.

1e7d2007c3 all: use designated initializers for AVOption.unit
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

8238bc0b5e avcodec/defs: Add AV_PROFILE_* defines, deprecate FF_PROFILE_* defines
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.

f264204de9 lavc: deprecate AV_CODEC_FLAG_DROPCHANGED
This decoding flag makes decoders drop all frames after a parameter
change, but what exactly constitutes a parameter change is not well
defined and will typically depend on the exact use case.
This functionality then does not belong in libavcodec, but rather in
user code

b92af7b64e avcodec/aacenc: add strict bit rate control option
In certain use cases, controlling the maximum frame size is critical. An
example is when transmitting AAC packets over Bluetooth A2DP.

While the spec allows the packets to be fragmented (but UNRECOMMENDED),
in practice most headsets do not recognize nor reassemble such packets.

In this patch, we allow setting `bit_rate_tolerance` to 0 to indicate
that the specified bit rate should be treated as an upper bound up to
frame level.

6b6f7db819 avcodec: add AVCodecContext.frame_num as 64 bit variant to frame_number
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.

e1a0f2df3d avcodec: add API for automatic handling of icc profiles
This functionally already exists, but as pointed out in #9672 and #9673,
requiring users to manually include filters is clumsy, error-prone and
hard to use together with tools like ffplay.

To streamline ICC profile support, add a new AVCodecContext flag to
globally enable reading and writing ICC profiles, automatically, for all
appropriate media types.

Note that this commit only includes the new API. The implementation is
split off to separate commits for readability.

f2da2e1458 libavcodec: Split version.h
This avoids including version.h in all source files, avoiding
unnecessary rebuilds when the version number is bumped. Only
version_major.h is included by the main header, which defines
availability of e.g. FF_API_* macros, and which is bumped much
less often.

This isn't done for libavutil/version.h, because that header needs
to be included essentially everywhere due to LIBAVUTIL_VERSION_INT
being used wherever an AVClass is constructed.

It is supported only by a few decoders (h263, h263p, mpeg(1|2|)video

work properly.
