This drastically simplifies the code. "ctdb reloadips" behaves the

This limitation can be removed with a reasonable amount of effort. It
probably isn't worth doing until the public IP address configuration
is stored in a cluster-wide database. That seems like the right time
to change the API to handle the details that
CTDB_CONTROL_GET_PUBLIC_IPS doesn't currently retrieve.

Databases should never be thawed manually. A database recovery will

The recovery lock can not be reliably updated at run-time. If it
fails to update on some nodes then split-brain protection is gone and
there is no reasonable way to repair the situation. CTDB will have to
be restarted on all nodes. So, if this feature is being used to avoid
scheduling an outage then an outage will have to be scheduled just in
case!
To update the recovery lock, shut down CTDB on all nodes, reconfigure
the recovery lock and start CTDB again.
Those that *really* want to be able to change the recovery lock at
run-time can still do so. Set CTDB_RECOVERY_LOCK to point to a script
and this script can then be modified at run-time. However, please
don't report bugs if bad things happen...

This simply calls out to the wrapper, so that commands are changed as
follows:
ctdb lvsmaster -> ctdb lvs master
ctdb lvs -> ctdb lvs list
This provides a simple, extensible interface and means that "ctdb lvs
status" is also available.
Unit tests are streamlined so that there is a single test for each
CTDB state. Each test does "master", "list" and "status" sub-tests.

It is pointless having a recovery lock but not sanity checking that it
is working. Also, the logic that uses this tunable is confusing. In
some places the recovery lock is released unnecessarily because the
tunable isn't set.
Simplify the logic by assuming that if a recovery lock is specified
then it should be verified.
