311dbab63d Allow failover_state objects to have their local-state field to be changed 
via OMAPI.  In addition, attempts to set other fields in a state object
will return success without modifying the object; this is very ugly, but
required to allow an open -> modify -> update sequence of OMAPI operations
to work properly.

988c1ca71f Added failover ack queueing. Failover update messages are no longer 
immediately responded to, but are placed on a queue (attached to
the dhcp_failover_state_t structure).  Updated leases are committed
only when the queue is drained, giving a significant performance
increase.

The toack queue is drained:
  a) when the queue size exceeds half the partner's max-unacked-updates
     setting, or
  b) two seconds after the last update message is received.

Added 'refcnt' and 'next' fields to the failover_message_t structure,
to allow messages to be placed on the toack queue.

On the sending side, leases are no longer committed immediately after
being acked.  Rather, the commit is deferred until no further acks are
pending.  This also gives a major gain in performance.

382f3632a9 Removed a log message from dhcp_failover_pool_rebalance() which generates 
a bit too much spam.

0980d1f7f9 Changed dhcp_failover_pool_rebalance() to defer committing updated 
leases until the rebalance has completed.  This gives a significant
performance gain when rebalancing large numbers of leases.

15c24b882b Changed supersede_lease() to return 1, even if the commit option is 
not specified.  (Before, it would always return 0 if commit was not
given.)  Fixed up the one call to supersede_lease() which expected
the old behavior.

Added a check to supersede_lease() to return an error if the pimmediate
flag is given, and commit is not.  (You should never be sending information
on an uncommitted lease to a peer.)

Separated the failover queue update (the propogate flag) test from
the commit test in supersede_lease(), so that you can now enqueue an
update on an uncommitted lease.

f7dca4c7b3 Remove the logic to rewrite the lease file every 1000 leases. This 
causes excessive slowness on systems with very large numbers of
leases.
