Handle SIGTERM in pg_receivewal and pg_recvlogical
In pg_receivewal, compressed output is only flushed on clean exits. The
reason to support SIGTERM as well as SIGINT (which is currently handled)
is that pg_receivewal might well be running as a daemon, and systemd's
default KillSignal is SIGTERM.
Since pg_recvlogical is also supposed to run as a daemon, teach it about
SIGTERM as well and update the documentation to match. While in there,
change pg_receivewal's time_to_stop to be sig_atomic_t like it is in
pg_recvlogical.
