based of the spl_kmem_obj_t tacked on the end of each object.
This actually isn't so back because we are now allocing large
chunks for the slab and partitioning it ourselves. So there's
not a ton of wasted space. We may suffer a performance hit
however due to alignment issues.
- Remove remaining depenancies on the linux slab implementation.
We're standing on our own now for better or worse.
- Rework slabs to be either kmem or vmem based. If neither
KMC_VMEM of KMC_KMEM are specified we make a decent guess
about what will work best for their based on the object
size. Additionally we provide a kmem_virt() function caller
can use to see if they have a virtual or physical address.
- Minor fixups in the test suite.
