fe758eda9f 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.

609453a848 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.

a82d37e48a 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.

No need to reconnect on every iteration of the loop. Move conditions
which break out of the loop straight away out of the loop.

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.

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.
