ctdbd: Add an index db for message list for faster searches

When CTDB is busy with lots of smbd, CTDB was spending too much time in
daemon_check_srvids() which searches a list of srvids in the registered
message handlers.  Using a hash based index significantly improves the
performance of search in a linked list.
