include/ruby/ruby.h: New structure RTypedData, added.
This structure incldues more explicit type information for
T_DATA objects. If RData(obj)->dfree is immediate value `1' on
T_DATA object obj, obj is needed to be accessed with RTYPEDDATA(obj)
instead of RDATA(obj). A RTypedData structure points the structure
rb_typed_data_t. rb_typed_data_t includes information such as the
type name of this data, mark and free function what RData includes,
and memsize function show how data consuming the memory size.
Note that you do not need any change existing T_DATA objects.
If you use RDataType instead of RData on T_DATA object,
you can specify explicit type information.
