ctdb-locking: Add per database queues for pending and active lock requests
This avoids traversing a single pending queue which is quite expensive
when there are lots of pending lock requests. This seems to happen
quite a lot on a loaded cluster for notify_index.tdb.
Adding per database queues avoids the need to traverse pending queue
for that database if there are already the maximum number of active
lock requests.
