Modified Files:
        src/sys/kern [ad-namecache]: vfs_subr.c vfs_vnode.c

Log Message:
vnodes:

- Have own v_usecount again, don't share the uvm_object's refcount.
- Cluster the members of vnode_t and vnode_impl_t in a cache-concious way.
- Go back to having vi_lock directly in vnode_impl_t.
- Go back to having v_usecount adjusted with atomics.
- Start adjusting v_holdcnt with atomics, too.
- Put all the namecache stuff back into vnode_impl_t.
