Make all allocators use the "kmem_cache" slabname for the "kmem_cache"
structure.

kmem_cache_destroy does basically the same in all allocators.
Extract common code which is easy since we already have common mutex
handling.

Use the mutex definition from SLAB and make it the common way to take a sleeping lock.
This has the effect of using a mutex instead of a rw semaphore for SLUB.
SLOB gains the use of a mutex for kmem_cache_create serialization.
Not needed now but SLOB may acquire some more features later (like slabinfo
/ sysfs support) through the expansion of the common code that will
need this.

All allocators have some sort of support for the bootstrap status.
Setup a common definition for the boot states and make all slab
allocators use that definition.
