Add operation vcache_rekey



The attached diff adds a new vcache operation

        void
        vcache_rekey(struct mount *mp, void *old_key, size_t old_key_len,
            void *new_key, size_t new_key_len)

to atomically change the key of a cached vnode.  As the key is no longer
constant remove "const" from all key arguments.

Comments or objections anyone?
