Move sections around to make the high availability chapter more
coherent: the most prominent part is now a "Log-Shipping Standby Servers"
section that describes what a standby server is (like the old
"Warm Standby Servers for High Availability" section), and how to

ControlFileLock when reading checkpoint location for %r.

The recovery_end_command bug and the missing locking was present in 8.4
