Add a memcg_iterate_all() function for iterating all the available
memory cgroups and call the given callback function for each of the
memory cgruops.

Why is a trivial wrapper any better than open coded usage of the
iterator?

Because the iterator is only defined within memcontrol.c. So an
alternative may be to put the iterator into a header file that can be
used by others. Will take a look at that.
