b80d25ad33 Add some hopefully correct comments for future reference 
Also some debugging output which will need to be removed later.

93d5d7905f Remove "XL*" macros and rationalize XLogRecPtr handling 
As of 9.3, XLogRecPtr is a uint64, which makes it much easier to
handle, so we can retire the legacy macros and work directly
with the values.

905a2d0a5e Have witness server retry determining the new master

526803c5e0 Witness server should always try to re-connect to primary 
Standbys will try to reconnect even in MANUAL_FAILOVER mode,
so it's consistent to have the witness server do that too.

8b69b1e16f Optionally retrieve server_version string as well 
In a couple of places we'll need to report the human-readable
version number

f94626bf7b Refactor version number detection 
Use the reported `server_version_num` integer for version number
detection and comparison. This makes it easier to set an arbitrary
minimum supported version (rather than "9.0 or later") as well
as future-proofing for 10.x and later.

d93d42fadb 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'.

98b1f8d28a 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.

9eba986833 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!

c3b58658ad 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

4496a0761e 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.

3978ead184 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.

b36dbf61fe reopening stdin and stdout to /dev/null now 
stdin, stdout and stderr should always be valid file handles. Thus we
don't close them but reopen them to /dev/null
