Implement sharing of vnode_t::v_interlock amongst vnodes:
- Lock is shared amongst UVM objects using uvm_obj_setlock() or getnewvnode().
- Adjust vnode cache to handle unsharing, add VI_LOCKSHARE flag for that.
- Use sharing in tmpfs and layerfs for underlying object.
- Simplify locking in ubc_fault().
- Sprinkle some asserts.

Discussed with ad@.

Reorganise UVM locking to protect P->V state and serialise pmap(9)
operations on the same page(s) by always locking their owner.  Hence
lock order: "vmpage"-lock -> pmap-lock.

Patch, proposed on tech-kern@, from Andrew Doran.

Change struct uvm_object::vmobjlock to be dynamically allocated with
mutex_obj_alloc().  It allows us to share the locks among UVM objects.
