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.

b6627a57f4 Revert "avcodec/mpeg12dec: Do not alter avctx->rc_buffer_size"
This reverts commit eb88ccb92e.

AVCodecContext fields are the proper place for a decoder to export such values.
This change is in preparation for the following commits.

avutil: add thread executor
The executor design pattern was introduced by java
<https://docs.oracle.com/en/java/javase/20/docs/api/java.base/java/util/concurrent/Executor.html>
it also adapted by python
<https://docs.python.org/3/library/concurrent.futures.html>
Compared to handcrafted thread pool management, it greatly simplifies the thread code.

lavu/tx: add real to real and real to imaginary RDFT transforms
These are in-place transforms, required for DCT-I and DST-I.

ff094f5ebb avutil/channel_layout: make pre-defined channel layouts C++ friendly
C++ doesn't support designated initializers until C++20. We have
a bunch of pre-defined channel layouts, the gains to make them
usable in C++ exceed the losses.

Bump minor version so C++ project can check before use these defines.

Also initialize .opaque field explicitly to reduce warning in C++.

dff3a283cd fftools/ffmpeg: rework -enc_time_base handling
Read the timebase from FrameData rather than the input stream. This
should fix  and generally be more reliable.

Replace the use of '-1' to indicate demuxing timebase with the string
'demux'. Also allow to request filter timebase with
'-enc_time_base filter'.

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

ac4247270c avdevice/decklink_enc: add support for SMPTE 2038 VANC packet output
Support decoding and embedding VANC packets delivered via SMPTE 2038
into the SDI output.  We leverage an intermediate queue because
data packets are announced separately from video but we need to embed
the data into the video frame when it is output.

Note that this patch has some additional abstraction for data
streams in general as opposed to just SMPTE 2038 packets.  This is
because subsequent patches will introduce support for other
data codecs.

Thanks to Marton Balint for review/feedback.
