AVOptions: do not range check flag options.
...
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).

avopt: Check whether the object actually has got an AVClass
...
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.

to children contexts.
