Instead of dealing with port@host in many places, do it where it is needed.

change return(0) to return(rv). We went to all the trouble to calculate the
return value, we might as well return it. (fixes lpq -a, and probably lpd)

Fix PR bin/14247
This PR claims that MacOSX 10.1 cannot print postscript files to a NetBSD
lpd because the mac will tag the file with an "o" for postscript, which
we do not handle. Rather than simply mapping o -> f as was done in the
PR, or mapping o -> l as was done in FreeBSD, I have implemented full
support for the "o" option. If a postscript filter does not exist in the
printcap file however, it will default to "l" handling.

With this change, you can now specify a "pf" or postscript filter in your
printcap, and have it handle postscript files sent to it with "lpr -o".

The "o" format in lpd is specified in RFC1179 as being a valid format flag.

in ckqueue() if "sd" is not an existing capability, than sd will be
uninitialized, causing the free() in out: to explode. Initialize sd to NULL.

Address PR bin/12112
Lpd has the ability to start on a port other than "printer" but has no
way to connect to a remote lpd on that port. This change adds the
ability to specify port@host in the rm element of printcap(5). Tested to
work with both a standard lpd setup and one running on special ports.
