How abount adding a new option hander to GiST/GIN support functions?

Presently, amoptions() are defined as
bytea *amoptions (ArrayType *reloptions, bool validate).
If there is a support function like this form in operator classes,
we can propagate options. Eventually, calling sequence will be
DefineIndex() -> amoptions() -> tsvectoroptions().

We also need to change gist/ginoptions() in order to determine what operator
class is used. This is a bit messy problem. Options are parsed before support
functions are initialized, so that I don't know in what form we should pass the
operator class to amoptions().
