hide struct internal [Feature #9916]

	* include/ruby/ruby.h (struct RStruct): no longer.

	* internal.h (struct RStruct): moved here.

	* struct.c (rb_struct_ptr): a compensation function for the lack
	  of RSTRUCT_PTR.  But now that we have RSTRUCT_GET/SET, that must
	  not be used anyway.  I mark this deprecated.  Dont use it.
