d4ee4cc14c "daemon stop": be careful with hints about "daemon status" 
If PostgreSQL is not running, "repmgr daemon status" can't be executed.

d7420d7274 daemon (start|stop): verify that repmgrd starts/stops. 
Note this may not always be possible for "daemon stop" if we are unable
to determine the repmgrd PID.

70e4243a1d Clean up calls to repmgr_atoi() 
In some places we were still providing "false" from the original implementation,
which was intended to indicate whether a negative value was allowed.

This has not been a problem, as it merely means we have been providing "0",
which is the same thing; however we can finer-tune some of the calls
(e.g. node ID must be or greater).

b6264b77c4 repmgr: mandate explicit configuration for "daemon (start|stop)" 
The initial implementation was designed to fall back to "manual"
start/stop of repmgrd if the "repmgrd_service_..._command" parameters
were not set.

However on reflection, this is too much of a potential footgun, so
we will mandate provision of these parameters.

a5aa47c1dd daemon start/stop: add warning about missing configuration 
repmgr will attempt to construct appropriate commands to start
and stop repmgrd, but usually it's preferable for them to be explicitly
defined, particularly if repmgr is installed from packages.

a9e09d436a doc: use "/current/" in URL path 
From the next major release, the current documentation will be located in the
"/docs/current/" subdirectory. This makes it easier to provide canonical
links to the latest version of the documentation (similar to how  the
main PostgreSQL documentation is organised).

Once the following major release is available, the documentation will be moved
to a subdirectory with the version number, e.g. "/docs/4.3/".

8881b69c06 "standby switchover": check remote data directory configuration 
The switchover will fail if the data_directory parameter in repmgr.conf
on the remote node (demotion candidate) is incorrectly configured.
We use the previously added "repmgr node check --data-directory-config
to verify this, and abort early if an issue is discovered.

Implements GitHub #523.
