1b4a98b029 lavu/opt: add a more general child class iteration API
Use opaque iteration state instead of the previous child class. This
mirrors similar changes done in lavf/lavc.

Deprecate the av_opt_child_class_next() API.

af9e622776 avutil/opt: add AV_OPT_FLAG_CHILD_CONSTS
This will be used for AVCodecContext->profile. By specifying constants in the
encoders we won't have to use the common AVCodecContext options table and
different encoders can use the same profile name even with different values.

6847affcb7 avutil/opt: only skip evaluation for rational options
Fixes problems when non-rational options were set using rational expressions,
causing rounding errors and the option range limits not to be enforced
properly.

ffmpeg -f lavfi -i "sine=r=96000/2"

This caused an assertion failure with assert level 2.

a500b975a8 avutil/opt: Don't use NULL for %s string in a log message
If one calls av_opt_set() with an incorrect string to set the value of
an option of type AV_OPT_TYPE_VIDEO_RATE, the given string is used in a
log message via %s. This also happens when the string is actually a
nullpointer in which case using it for %s is forbidden.

This commit changes this by erroring out early in case of a nullpointer.

This also fixes a warning from GCC 9.2:
"‘%s’ directive argument is null [-Wformat-overflow=]"

9e0a071ede avutil/opt: Print out numeric values of option constants
It's often not obvious how option constants relate to numerical values.
Defaults are sometimes printed as numbers and from/to are always printed as numbers.
Printing the numeric values of options constants avoids this confusion.
It also allows to see which constants are equivalent.

Before this patch:

  -segment_list_type <int>        E........ set the segment list type (from -1 to 4) (default -1)
     flat                         E........ flat format
     csv                          E........ csv format
     ext                          E........ extended format
     ffconcat                     E........ ffconcat format
     m3u8                         E........ M3U8 format
     hls                          E........ Apple HTTP Live Streaming compatible

Afterwards:

  -segment_list_type <int>        E........ set the segment list type (from -1 to 4) (default -1)
     flat            0            E........ flat format
     csv             1            E........ csv format
     ext             3            E........ extended format
     ffconcat        4            E........ ffconcat format
     m3u8            2            E........ M3U8 format
     hls             2            E........ Apple HTTP Live Streaming compatible

Integer values should not be printed using format specifier '%g' which leads to inexact display in case of higher values.

Before this patch:
