mm, memcg: create mem_cgroup_from_seq
This is the start of a series of patches similar to my earlier DEFINE_MEMCG_MAX_OR_VAL work, but with less Macro Magic(tm). There are a bunch of places we go from seq_file to mem_cgroup, which currently requires manually getting the css, then getting the mem_cgroup from the css. It's in enough places now that having mem_cgroup_from_seq makes sense (and also makes the next patch a bit nicer).
