fix: witness creation and monitoring
...
While reading node entries from master use a separate PGresult when inserting into witness.
Witness monitoring supplies a null value for 'last_apply_time'.

rather big refactoring: use a naming scheme
...
In the past naming of functions, variables and such didn't really have a
naming scheme. Now they should have.

avoid usage of snprintf()

We have a nice little abstraction for snprintf with covering the case
that a string is too big for the target buffer – let's use that!

fixing repmgr repl_status columns
...
repmgr repl_status had the column time_lag which was documented to be
the time a standby is behind master. In fact it only works like this
when viewed on the standby and not on the master: there it only was the
time of the last status update. We dropped that column and replaced it
by a new column „communication_time_lag“ which is the content of the
repl_status column on the master. On the standby we contain the time of
the last update in shared mem though refer always to the correct time
nonetheless where repl_status is queried. We also added a new column,
„replication_time_lag“, which refers to the apply delay.

We do not need fsync(), the fflush() is enough to avoid concurrent

we now use a function and are more sophisticated
...
Refactoring part: we now use a function to generate the PID
file. Sophistication: we now check if the PID contained in the file is a
valid PID. We ignore the file if it doesn't.

use a second fork to avoid a terminal
...
after the setsid() we are the process leader. And as a process leader we
are able to open a new terminal, even if we currently don't own one. So
we do another fork and do not call setsid() and not become a process
leader to avoid that.

reopening stdin and stdout to /dev/null now

fix: fail when repmgr_funcs is not pre-loaded
...
when repmgr_funcs is not pre-loaded `repmgr_update_standby_location()`
will return false and `repmgr_get_last_standby_location()` will return
an empty string. Thus we may end in an endless loop. To avoid that we fail.

fix: flushing and fsync()ing the log file
...
When not flushing and fsync()ing it the output may be garbled due to
concurrent writes to the file (system() spawns a child process with
stdin/stdout/stderr inherited from it's parent)

added config options sleep_delay and sleep_monitor
...
sleep_monitor replaces the old SLEEP_MONITOR define and makes it
configurable; this is the interval in which we monitor
sleep_delay replaces the old sleep(300) when waiting for the master to
recover.

database connections.
