locks: added inodelk/entrylk contention upcall notifications
The locks xlator now is able to send a contention notification to
the current owner of the lock.
This is only a notification that can be used to improve performance
of some client side operations that might benefit from extended
duration of lock ownership. Nothing is done if the lock owner decides
to ignore the message and to not release the lock. For forced
release of acquired resources, leases must be used.
