Make refinements to r212824.  In particular, don't make
vm_map_unlock_nodefer() part of the synchronization interface for maps.

Add comments to vm_map_unlock_and_wait() and vm_map_wakeup() describing
how they should be used.  In particular, describe the deferred deallocations
issue with vm_map_unlock_and_wait().

Redo the implementation of vm_map_unlock_and_wait() so that it passes
along the caller's file and line information, just like the other map
locking primitives.
