Get rid of the stupid hack that makes this lose when ${CC} is more than one word.

Just remove the first word so that rcmd.c compiles even if the command line
contains same substrings with the name of compiler.

usr.sbin/lpr/lpd now compiles lib/libc/net/rcmd.c on its own, to avoid
use of non-exported function __ivaliduser{,_sa}().

we cannot make __ivaliduser{,_sa}() static yet, since doing that would choke

this changes function prototype for __ivalid*.
This commit breaks binary compatibility for __ivalid*. I believe this can be
forgiven due to the following:
- this is not really exported function. no function prototype is in headers.
function name starts with underbars. No third-party applications are
expected to use it.
- the function was introduced very recently, when rcmd.c was made IPv6-ready.
- the only customer in NetBSD tree is lpd.

Fix PR bin/30272 Lpd would create the tempfile "remotexxxxx" and send

filter)

Update a comment regarding control file WRT "o"

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.

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.
