Ignore server-side delays when enforcing wal_sender_timeout. Healthy clients of servers having poor I/O performance, such as buildfarm members hamster and tern, saw unexpected timeouts. That disagreed with documentation. This fix adds one gettimeofday() call whenever ProcessRepliesIfAny() finds no client reply messages. Back-patch to 9.4; the bug's symptom is rare and mild, and the code all moved between 9.3 and 9.4.
