This patch introduces the cgroup/cpuset-v1.c source file which will be used for all legacy (cgroup v1) cpuset cgroup code. It also introduces cgroup/cpuset-internal.h to keep declarations shared between cgroup/cpuset.c and cpuset/cpuset-v1.c. As of now, let's compile it if CONFIG_CPUSET is set. Later on it can be switched to use a separate config option, so that the legacy code won't be compiled if not required.
