984d0b6e6f pixdesc: add limited|full aliases for -color_range parameter 
Aliases are also used in scale and zscale filters.

Tested:
```
$ ./ffmpeg -hide_banner -y -i ~/src/media/images/y4m/lena.490x490.y4m  -pix_fmt yuv420p -color_range unknown /tmp/unknown.y4m
...
$ md5sum /tmp/unknown.y4m

7d1d61cc5f lavc: deprecate AVCodecContext.ticks_per_frame 
For encoding, this field is entirely redundant with
AVCodecContext.framerate.

For decoding, this field is entirely redundant with
AV_CODEC_PROP_FIELDS.

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.

337fe4bcc2 avcodec/options_table: make AVCodecContext->profile search for child constants 
This change makes it possible for child encoders to define custom profile
option names which can be used for setting the AVCodecContext->profile.

Also rename unit name to something rather unique, so it won't be used elsewhere.

abb69a2f2b avcodec: Add "sar" alias to "aspect" option of video encoders 
It is impossible to pass "aspect" parameter to encoder from ffmpeg CLI
because option from lavc/options_table.h is eclipsed by option with same
name in ffmpeg_opt.c, which has different meaning (DAR, not SAR).
