Suren Baghdasaryan 21c690a349 mm: introduce slabobj_ext to support slab object extensions
Currently slab pages can store only vectors of obj_cgroup pointers in
page->memcg_data.  Introduce slabobj_ext structure to allow more data to
be stored for each slab object.  Wrap obj_cgroup into slabobj_ext to
support current functionality while allowing to extend slabobj_ext in the
future.
