Improve my hack from rev 1.6 of displayq.c, and make the TCP

connection timeout controllable by a new printcap(5) capability named
`ct' (connectiom timeout), defaulting to 120 seconds (which is the
default TCP connection timeout).

Would anybody see a problem with merging all this into RELENG_2_2?
