c0eea90402 Cascading replication support for Barman mode 
If upstream_node is specified, we point the standby to that node;
otherwise we point it to the current primary node.

135fa2e1b9 Fixing primary_conninfo generation (#232) 
After introducing Barman mode, it is no longer true that STANDBY CLONE
can derive primary_conninfo from the connection to the master. Now we
ask Barman how to connect to a valid cluster node, and then we fetch
the conninfo for the current master from repmgr metadata.

2a8861be8b Fixing inaccurate option checking (#230) 
The incompatibility between Barman mode and use_replication_slots was
not checked properly, and did not cause repmgr to exit.

ef7bed1b3d repmgrd: refactor standby monitoring status query and code

cb78802027 repmgrd: prevent endless loops in failover with manual node 
The LSN reported by the shared memory function defaults to "0/0"
(InvalidXLogRecPtr) - this indicates that the repmgrd on that node
hasn't been able to update it yet. However during failover several
places in the code assumed this is an error, which would cause
an endless loop waiting for updates which would never come.

To get around this without changing function definitions, we can
store an explicit message in the shared memory location field so the
caller can tell whether the other node hasn't yet updated the field,
or encountered situation which means it should not be considered
as a promotion candidate (which in most cases will be because
`failover` is set to `manual`.

Resolves GitHub #222.

ccdc0f9871 Improved "repmgr-auto" Debian package 
* Version set to 3.2dev

* Binaries are placed in PGBINDIR and then linked from /usr/bin,
  instead of being placed into /usr/bin directly. This is necessary
  for the switchover command, because it requires pg_rewind, which is
  placed in PGBINDIR too.
