If people want, this could be exported as av_opt_size()

Existing av_opt_set_dict doesn't accept flags.
It doesn't allow to pass options to nested structs.
New function alllows that.

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.

INT_MAX is used here to denote the max allowed value for a pixel 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.

Simplify incoming patch.

In particular, allow to reject undefined values. Previously the code
was only accepting values in the range -1 .. NB_FORMATS-1.

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).

The new type is compatible with AV_OPT_TYPE_INT64, but allows to specify
channel layouts using the format accepted by av_get_channel_layout().

In particular, do not set default string value by hand and use
av_opt_free() to free context.
