* ext/objspace/objspace.c: add ObjectSpace#reachable_objects_from.
This method returns an array of objects referenced by given object. If given object is special objects such as true/false/nil/Fixnum etc then it returns nil. See rdoc for details. [ruby-core:39772] * test/objspace/test_objspace.rb: add a test for this method. * gc.c: add rb_objspace_reachable_objects_from(). To make this function, add several member `mark_func_data' to rb_objspace_t. If mark_func_data is not null, then gc_mark() calls mark_func_data::mark_func. * gc.h: export rb_objspace_reachable_objects_from(). git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
