Fix assorted Makefile bugs
...
1. The target additional-maintainer-clean was misspelled as
maintainer-additional-clean.
2. Add add missing clean targets, in particular sysutils.o, config.h,
repmgr_version.h, and Makefile.global. While at it, use a wildcard
for obj files.
3. Don't delete configure.
4. Remove generated file doc/version.sgml from the repo.
5. Have maintainer-clean recurse to the doc directory.

repmgrd: enable election rerun

If "failover_validation_command" is set, and the command returns an error,
rerun the election.
There is a pause between reruns to avoid "churn"; the length of this pause
is controlled by the configuration parameter "election_rerun_interval".

situation.
This setting is only used when "standby_disconnect_on_failover" is set to "true".

however need to reset "wal_retrieve_retry_interval".

Log warning if "standby_disconnect_on_failover" used on pre-9.5

"standby_disconnect_on_failover" requires availability of "wal_retrieve_retry_interval",
which is available from PostgreSQL 9.5.
9.4 will fall out of community support this year, so it doesn't seem
productive at this point to do anything more than put the onus on the user
to read the documentation and heed any warning messages in the logs.

repmgrd: optionally disconnect WAL receivers during failover
...
This is intended to ensure that all nodes have a constant LSN while
making the failover decision.
This feature is experimental and needs to be explicitly enabled with the
configuration file option "standby_disconnect_on_failover".
Note enabling this option will result in a delay in the failover decision
until the WAL receiver is disconnected on all nodes.
