b79bce5821 Support tablespace mapping in --rsync-only mode 
This makes it practical to take a back with rsync where tablespaces
require remapping. It also makes tablespace remapping possible for
9.3, where pg_basebackup does not support this option.

Better simulate what goes on in 'src/backend/replication/basebackup.c';
avoid copying some files/directories introduced in 9.4.

32611f5f04 Add --rsync-only option 
Sometimes it's desirable to re-sync a "stale" data directory
on a standby, rather than start from scratch with pg_basebackup().

This re-adds the rsync code from the 2.x series, with some
modifications.

TODO: tablespace support.

eabb3cb1ab Add "--checksum" in rsync when using "--force" 
If the user don't put that option in rsync_options using of "--force"
could be unsafe.
While the probability of failures because of this are low they aren't
zero.

a3f0e89a05 Improve pg_bindir parameter handling 
Previously, the pg_bindir parameter was mandatory and could only be
provided in the repmgr.conf file, which was leading to the slightly
bizarre situation that e.g. for "clone standby", repmgr was complaining
that it didn't want the configuration file when it actually did.

pg_bindir is now optional - if not provided, it will use the default
path. It can be provided in the repmgr.conf file, or as a command
line parameter; the latter overrides the former.

3d9d0d98af Improve repmgr configuration file handling 
Previous behaviour was somewhat counterintuitive, with an error
message being logged if no configuration file provided or found,
even though this is not actually an error.

Configuration files now handled like this:

- if a configuration file is explicitly provided (-f), error out
  if not found.

- if no configuration file explicitly provided, attempt to open
  default configuration file; if this does not exist, log
  notice and continue with default values.

Also, for 9.4 and later add a hint about replication slot usage
if 'use_replication_slots' not set.

a82d37e48a Improve node metadata and upstream connecting mechanism

of each node's upstream node. Also enumerate the node type
("primary", "standby" or "witness") and mark if active.
