mm/sl[aou]b: Move kmallocXXX functions to common code
The kmalloc* functions of all slab allcoators are similar now so lets move them into slab.h. This requires some function naming changes in slob. As a results of this patch there is a common set of functions for all allocators. Also means that kmalloc_large() is now available in general to perform large order allocations that go directly via the page allocator. kmalloc_large() can be substituted if kmalloc() throws warnings because of too large allocations. kmalloc_large() has exactly the same semantics as kmalloc but can only used for allocations > PAGE_SIZE.
