It makes sense to do this in the "init" event and make the initscript

This avoids premature exits from "ctdb stop" and "ctdb continue" due to
intermittent control (e.g. getpnn, getnodemap) timeouts.
This needs a proper fix to distinguish between timeout and failure
conditions and take appropriate action.

If getpgrp() fails, it will return -1 and that will send KILL signal to init
process (PID 1). This does not happen on RHEL, but does on AIX.

If some nfsd threads are still alive after a shutdown during a restart
then this indicates the maximum number of threads for which a stack
trace should be dumped. This can be useful for trying to determine
why nfsd is stuck.

Consider the following example:
1. There are 256 nfsd threads configured.
2. 200 threads are "stuck" in system calls, perhaps waiting for the
underlying filesystem when an attempt is made to restart NFS.
3. 56 threads exit when NFS is stopped.
4. 56 new threads are started when NFS is started.
5. 200 "stuck" threads exit leaving only 56 threads running.
Setting this option to "yes" makes the 60.nfs monitor event look for
this situation and try to correct it.

60.nfs and 60.ganesha touch $statd_update_trigger every time they're
run. This stops the statd-callout updates from ever being called.
Make this logic self-contained and move it to new function
nfs_statd_update() in the functions file. Call this in 60.nfs and
60.ganesha with the appropriate update period as the only argument.

Every time a node that wasn't the NAT gateway master gets reconfigured
something like this appears in the log:
ctdbd: 11.natgw: Failed to del 10.0.1.139 on dev eth1
Since this usually fails it is better to mute the error than to have
it pollute the log.

Consider the case of upgrading a cluster node by node, where some
nodes are still running older versions of CTDB without the
IPREALLOCATED control. If a "new" node takes over as recovery master
and a failover occurs, then it will attempt to send IPREALLOCATED
controls to all nodes. The "old" nodes will fail in a fairly
nondescript way (result == -1).
To try to handle this situation, fall back to the EVENTSCRIPT control
to handle "ipreallocated". Only do this on the failed nodes.
However, do not do this on nodes that timed out (they've probably
implemented the control and we should call the regular fail_callback
to get those nodes banned) or for stopped nodes (since they can't
actually run the "ipreallocated" event via the EVENTSCRIPT control).
