* gc.c: fix memory leak by prepend method.
It is easy to reproduce with such script:
module M; def bar; end; end
loop{
Class.new do
def foo; end
prepend M
end
}
* gc.c (obj_free): free T_ICLASS::m_tbl if it is created by prepend.
To recognize it, check RICLASS_IS_ORIGIN flag.
* gc.c (gc_mark_children): T_ICLASS objects only need to mark
T_ICLASS::m_tbl if RICLASS_IS_ORIGIN is set.
* gc.c (obj_memsize_of): count T_ICLASS if RICLASS_IS_ORIGIN is set.
* internal.h (RCLASS_SET_ORIGIN): add to set RCLASS_SET_ORIGIN.
TODO: The word `origin' seems not good name. We need to invent
another good name.
* class.c: use RCLASS_SET_ORIGIN().
* class.c (class_alloc): zero clear rb_classext_t.
