Zygo Blaxell 8ea92202fc lockset: avoid starvation using a priority queue ...

Mutex locks are released and acquired unfairly, causing arbitrary delays
in acquiring locks.  This prevents threads from releasing subvol FD's
which in turn blocks subvol deletes.

Fix by implementing a priority queue in LockSet to ensure fairness.
