Here is the patch to rename 'lang' to 'lang_ops'.  Committed as obvious.

gdb:

2013-10-27  Yao Qi  <yao@codesourcery.com>

	* varobj.c (struct varobj_root) <lang>: Rename to 'lang_ops'.
	(varobj_create, varobj_get_path_expr): Update.
	(varobj_value_has_mutated, varobj_update): Likewise.
	(create_child_with_value, new_root_variable): Likewise.
	(number_of_children, name_of_variable): Likewise.
	(value_of_child, my_value_of_variable): Likewise.
	(varobj_value_is_changeable_p): Likewise.
