The Ubuntu 10.04 autobuilds on sn-devel build the lib/* libraries into
their own bin subdirectories; for example lib/ldb uses lib/ldb/bin. A
recent commit broke these autobuilds by un-hiding these directories
from git.

If a recovery is going to be done then this will be followed by a
takeover run anyway. So, there's no use doing the takeover run
checks, potentially doing a takeover run and then doing a recovery.

The recovery daemon should be less involved in the service monitoring
logic.
The cases handled here are already handled elsewhere:
* When a node becomes unhealthy/healthy the monitoring code will
trigger a takeover run
* When a node is disabled/enabled the ctdb CLI tool will trigger a
takeover run

Banning is now handled by the takeover code sending banning credit
messages.
This commit makes a change in behaviour quite obvious. Takeover runs
were initiated from several locations in the code but banning was only
done from one of these locations. Now banning can be done from any
failed takeover run.

Post-process failues and only send banning credits to the node with

If there is a widespread problem or a problem on the recovery master
node then this should help avoid banning all the nodes.

This will allow banning credits assignments to be limited according to
some criteria.
Note that this only matters when multiple controls are sent to each
node: RELEASE_IP and TAKEOVER_IP. This doesn't change the behaviour
for IPREALLOCATED.

Banning credits are now assigned by takeover runs called from all
locations in the recovery daemon. Previously this only happened from
one of the callers. When separating out the takeover run code the
behaviour should be consistent.
The callback (and corresponding data) passed to ctdb_takeover_run() is
now ignored. Dropping this will allow the interface between the
recovery daemon and IP takeover to be simplified.

Probably due to oversight, this is currently only used for the
"takeip" step.
This does consistent error handling and provides a layer of
indirection to the passed callback, so use it for "releaseip" and
"ipreallocated" steps too.
The callback data now needs to be initialised before the first
possible jump to "ipreallocated".
