f37b3cf2a6 ctdb: Change LVS to use leader/follower
Instead of master/slave.

Nearly all of these are simple textual substitutions, which preserve
the case of the original.    A couple of minor cleanups were made in the

46684867b1 ctdb-recovery: Recovery lock setting can now include helper command
The underlying change is to allow the cluster mutex argstring to
optionally contain a helper command.  When the argument string starts
with '!' then the first word is the helper command to run.  This is
now the standard way of changing the helper from the default.

CTDB_CLUSTER_MUTEX_HELPER show now only be used to change the location
of the default helper when testing.

ce33a7cb1e ctdb-scripts: Call out to ctdb_lvs helper from 91.lvs
To keep this commit comprehensible, 91.lvs and the CTDB CLI tool are
temporarily inconsistent.  The tool will be made consistent in a
subsequent commit.

LVS now uses a configuration file specified by CTDB_LVS_NODES and
supports the same slave-only syntax as CTDB_NATGW_NODES.  LVS also
uses new variable CTDB_LVS_PUBLIC_IFACE instead of
CTDB_PUBLIC_INTERFACE.

Update unit tests and documentation.

Note that the --lvs and --single-public-ip daemon options are no
longer used.  These will be removed and relevant documentation
updated in a subsequent commit.

f4fc9a153c ctdb-logging: Remove debug levels DEBUG_ALERT and DEBUG_CRIT
Internally map them to DEBUG_ERR to limit code churn.

This reduces the unwieldy number of debug levels used by CTDB.  ALERT
and CRIT aren't of much use as separate errors, since everything from
ERR up should always be logged.  In future just ERR can be used.

This also improves compatibility with Samba's debug.c system priority
mapping.
