avcodec_enum_to_chroma_pos() and avcodec_chroma_pos_to_enum()
deal with enum AVChromaLocation which is defined in lavu.
These functions are therefore replaced by
av_chroma_location_enum_to_pos() and av_chroma_location_pos_to_enum().
This commit provides the necessary deprecations. Also already make
these functions wrappers around the corresponding lavu functions
as not doing so would force one to disable deprecation warnings.

They are also frequently used in libavformat.
This change does not cause any breakage as avcodec.h
includes defs.h.

Mention:
- that it is legacy and optional (every hwaccel that uses it can also
work with hwcontext, though some optional information can only be
signalled throught hwaccel_context)
- that it can be used for encoders (only qsvenc currently)
- ownership and lifetime
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.

This avoids unnecessary churn and build breakage for users, by
making sure the whole version.h is included like it has been so far,
while keeping the benefit of not needing to rebuild most files in
the ffmpeg tree on minor/micro bumps.

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.

Since the request_channel_layout is used only by a handful of codecs,
move the option to codec private contexts.

avcodec_open2() is supposed to be thread-safe (those codecs
whose init functions are not thread-safe are guarded
by a global lock).

It is supported only by a few decoders (h263, h263p, mpeg(1|2|)video
and mpeg4) and is entirely redundant with parsers. Furthermore, using
it leads to missing frames, as flushing the decoder at the end does not
work properly.

Remove some incorrect (or at least misleading) statements, such as the
formats being ordered by quality, or the first format being the native
one. Neither of those are true for hardware acceleration, which is the
main use of this callback.

Two FATE-tests needed to be updated because the checksums of
