This option, which is also available on other FFmpeg hardware encoders,
allows the user to trade throughput for reduced output latency. This is
useful for ultra low latency applications like game streaming.

Enable waiting in QueryOutput() based on driver support to reduce
unnecessary delays.
Fix for issue #10622

I went through all codecs and put them into five basic categories:
1. JPEG range only
2. MPEG range only
3. Explicitly tagged
4. Broken (codec supports both but encoder ignores tags)
5. N/A (headerless or pseudo-formats)
Filters in category 5 remain untouched. The rest gain an explicit
assignment of their supported color ranges, with codecs in category
4 being set to MPEG-only for safety.
It might be considered redundant to distinguish between 0 (category 5)
and MPEG+JPEG (category 3), but in doing so we effectively communicate
that we can guarantee that these tags will be encoded, which is distinct
from the situation where there are some codecs that simply don't have
tagging or implied semantics (e.g. rawvideo).
A full list of codecs follows:
JPEG range only:
- amv
- roqvideo
MPEG range only:
- asv1, asv2
- avui
- cfhd
- cljr
- dnxhd
- dvvideo
- ffv1
- flv
- h261, h263, h263p

- libopenjpeg
- libtheora
- libwebp, libwebp_anim
- libx262
- libxavs, libxavs2

- mpeg1video, mpeg2video
- mpeg2_qsv
- mpeg2_vaapi
- mpeg4, msmpeg4, msmpeg4v2, wmv1, wmv2
- mpeg4_omx
- prores, prores_aw, prores_ks
- rv10, rv20
- snow
- speedhq
- svq1
- tiff
- utvideo
Explicitly tagged (MPEG/JPEG):
- {av1,h264,hevc}_nvenc
- {av1,h264,hevc}_vaapi
- {av1,h264,hevc,vp8,vp9,mpeg4}_mediacodec

- libaom-av1
- libkvazaar
- libopenh264
- librav1e
- libsvtav1
- libvpx, libvpx-vp9
- libx264
- libx265
- ljpeg
- mjpeg
- vc2
Broken (encoder ignores tags):
- {av1,hevc}_amf
- {h264,hevc,mpeg4}_v4l2m2m
- h264_omx
- libxeve
- magicyuv
- {vp8,vp9,mjpeg}_vaapi
N/A:
- ayuv, yuv4, y41p, v308, v210, v410, v408 (headerless)
- pgmyuv (headerless)
- rawvideo, bitpacked (headerless)
- vnull, wrapped_avframe (pseudocodecs)
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
Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;
also avoids relocations.

This commit fixes issue with missing SPS/PPS headers in video
encoded by AMF AV1 encoder.
Missing headers leads to broken seek in MPV video player.
Default value for property AV1_HEADER_INSERTION_MODE shouldn't be setup
to NONE (no headers insertion). We need to skip definition of this property,
because default value depends on USAGE property.

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.

For encoding, this field is entirely redundant with
AVCodecContext.framerate.
For decoding, this field is entirely redundant with
AV_CODEC_PROP_FIELDS.
