This patch introduces the mm/memcontrol-v1.c source file which will be used for all legacy (cgroup v1) memory cgroup code. As of now, let's compile it if CONFIG_MEMCG is set, similar to mm/memcontrol.c. Later on it can be switched to use a separate config option, so that the legacy code won't be compiled if not required.
