96100fcae6 added two new ctdb commands:
ctdb vacuum   : vacuums all the databases, deleting any zero length
                 ctdb records

 ctdb repack   : repacks all the databases, resulting in a perfectly
                 packed database with no freelist entries

50573c5391 add ctdb_disable/enable_monitoring() that only modifies the monitoring
flag.
change calling of the recovered/takeip/releaseip event scripts to use 
these enable/disable functions instead of stopping/starting monitoring.

when we disable monitoring we want all events to still be running
in particular the events to monitor for dead nodes  and we only want to 
supress running the monitor event scripts

8ac8cce487 dont manipulate ctdb->monitoring_mode directly from the SET_MON_MODE
control, instead call ctdb_start/stop_monitoring()

ctdb_stop_monitoring() dont allocate a new monitoring context, leave it 
NULL. Also set the monitoring_mode in this function so that 
ctdb_stop/start_monitoring() and ->monitoring_mode are kept in sync.
Add a debug message to log that we have stopped monitoring.

ctdb_start_monitoring()  check whether monitoring is already active and 
make the function idempotent.
Create the monitoring context when monitoring is started.
Update ->monitoring_mode once the monitoring has been started.
Add a debug message to log that we have started monitoring.

When we temporarily stop monitoring while running an event script,
restart monitoring after the event script wrapper returns instead of in 
the event script callback.

Let monitoring_mode start out as DISABLED and let it be enabled once we call ctdb_start_monitoring.

dont check for MONITORING_DISABLED in check_fore_dead_nodes(). If 
monitoring is disabled, this event handler will not be called.

ce7a054d20 add back the test inside the daemon that if someone asks us to drop
recovery mode back to NORMAL that we can not lock the reclock file   
since at this stage it MUST be locked by the recovery daemon.

in order to avoid a non-blocking fnctl() lock from blocking and cause 
"issues"  we move the 'test that we can not lock reclock file' into a 
child process.

b3ff7d904d dont try to lock the file from inside the ctdb daemon.
eventhough we dont want a blocking lock it does appear that the fcntl()
call can block for a while if gpfs is in the process of rebuilding 
itself after a node arriving/leaving the cluster

12ebb74838 change how we do public addresses and takeover so that we can have
multiple public addresses spread across multiple interfaces on each 
node.

this is a massive patch since we have previously made the assumtion that 
we only have one public address per node.

get rid of the public_interface argument.  the public addresses file 
now explicitely lists which interface the address belongs to
