Update repl_nodes following failover
...
repl_nodes table updated by each node following failover to
show that either it is the primary, or which primary it has
started to follow.

Handle failover of top-level standby
...
Cascaded standbys will not go into failover so we need to ignore
these when looking for candidates for promotion.

Improve node metadata and upstream connecting mechanism
...
To handle cascaded replication we're going to have to keep track
of each node's upstream node. Also enumerate the node type
("primary", "standby" or "witness") and mark if active.

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.

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'.
