* include/ruby/ruby.h: introduce new flags for T_TYPEDDATA.

Browse source 
* RUBY_TYPED_FREE_IMMEDIATELY: free the data given by DATA_PTR()
    with dfree function immediately.  Otherwise (default), the data
    freed at finalizaton point.
  * RUBY_TYPED_WB_PROTECTED: make this object with FL_WB_PROTECT
    (not shady).
* gc.c (obj_free): support RUBY_TYPED_FREE_IMMEDIATELY.
