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.
