This change make error handling simplier.
av_opt_freep_ranges may be called when some ranges are NULL,
for example after memory allocation fail.

AVOptionRange is not flexible enough to store AV_OPT_TYPE_IMAGE_SIZE
ranges. Current implementation can only store pixel count.
This patch aims to keep backward compatibility and extend
AVOptionRange with possibility to store width/height ranges.

The constant may change in libavutil but the library may be compiled
against an older version, thus rejecting a value which is otherwise
supported by the new libavutil.
INT_MAX is used here to denote the max allowed value for a sample format.
The opt-test code is changed to provide a valid reference example.

Previously when setting a pixel/sample format as a string range checks
were not performed. This is consistent with the
av_opt_set_pixel/sample_fmt() interface.

It does not make sense in the vast majority of use cases, no currently
defined AV_OPT_TYPE_FLAGS options in Libav set the range to anything
nontrivial, and many of those get it wrong (the "correct" range is
INT_MIN to INT_MAX so that the builtin constant "all" works).

AVIOContext has got an av_class member that only gets set if
opening the context using avio_open2, but not if allocating a
custom IO context. A caller that wants to read AVOptions from
an AVIOContext (recursively using AV_OPT_SEARCH_CHILDREN) may
not know if the AVIOContext actually has got a class set or not.

This change requires the user to specify min and max value, and makes
possible to prevent the user to set AV_{SAMPLE,PIX}_FMT_NONE if
forbidden.
Add required ifdeffery in case of mixed libraries, when libavutil is
updated but not the other libraries.
This is a followup of 08d0969c14.
Use the i64 field rather than the string value. Using a string to set a
default sample/pixel format is weird, also the new interface is more
consistent with the rest of the API.
This is technically an API break, but hopefully there are no applications
using this feature outside of FFmpeg. In order to save backward
compatibility with mixed libraries in case libavutil is updated but not
the other libraries, some ifdeffery hacks are added.
Note that the version check is only performed when class->version != 0,
since if it is not defined then we assume that no version was defined and
the class is not affected by the change.
We will luckily get rid of the hack at the next major bump.
This function does the low-level work of av_opt_set_from_string()
but can be used when there is no option context or when a generic
handling of unknown keys is needed.
av_opt_set_from_string() is changed to make use of it.
It is similar to av_set_options_string() but accepts a list
of options that can be in shorthand: if the key is omitted
on the first fields, the keys from the shorthand list are
assumed, in order.
