ef7bed1b3d repmgrd: refactor standby monitoring status query and code 
This had grown somewhat complex with addition of handling for
various corner cases. Much of the work has now been delegated
to the query itself.

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.

02668ee045 Parse the contents of the "pg_basebackup_options" parameter in repmgr.conf 
This is to ensure that when repmgr executes pg_basebackup it doesn't
add any options which would conflict with user-supplied options.

This is related to GitHub #206, where the -S/--slot option has been
added for 9.6 - it's important to check this doesn't conflict with
-X/--xlog-method.

While we're at it, rename the ErrorList handling code to ItemList
etc. so we can use it for generic non-error-related lists.
