c7e921a54f 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.

5efbeae38c configure: rename have_incompatible_fork_abi -> have_incompatible_libav_abi 
"Fork" is an ambiguous term, since there may be more than one fork, also
"fork" could be confused with the corresponding function. Also it seems
important to point the name of the referenced fork in the symbol.

Note: the old --enable-incompatible-fork-abi command is retained for
compatibility, although it should be considered deprecated.
