777c634eae add TDB_NO_NESTING. When this flag is set tdb will not allow any nested transactions and tdb_transaction_start() will implicitely _cancel() any pending transactions before starting any new ones.

38ea6708dd add a tuneable RecoveryDropAllIPs so it is possible to control after how long a node that has been stuck in recovery will wait until it will yield all public addresses. 
this now defaults to 60 seconds

This is useful if a split brain occurs due to network partitioning since it will make sure that the "other half" of the cluster that does not contain the recovery master will eventually release all ips and thus avoiding a duplicate ip situation for the public addresses

37e2417c59 change shutdown level for ctdb to be 01 
We want ctdb to shutdown first, as it manages many other
services. With the old level of 32 the NFS service would shutdown
first, and that would trigger ctdb to do a recovery. Then ctdb itself
would be shutdown a few seconds later, which causes a lot of error
messages in the other nodes logs

d94917ec49 Change the (dodgy) seqnumfrequency variable to have ms resolution instead of second resolution. 
Rename the variable to SeqnumInterval for
1, it is an interval and not a 1/interval unit
2, so that we catch when people use this old variable and can update the sysconfig file instead of silently changin semantics of this variable

this is a real dodgy variable

b9e6e15cd4 we must also try to set the routes when we release an ip since during the release/10.interfaces there can actually be a window where the kernel decides to remove all addresses (before we manually add them back in 10.interfaces) during which the kernel may also decide to delete all routes since there are no gateways reachable through this interface anymore.

   OUTPUT:ERROR: Samba tcp port 445 is not responding

Add a new helper function "switch_from_server_to_client()" which both
the recovery daemon can use as well as in the child process we start for running the actual eventscripts.

Create several new controls, both for the eventscript child process to inform the master daemon of the current status of the scripts as well as for the ctdb tool to extract this information from the runninc daemon.
