Properlay clean the global RM variable if cgetstr() failed for it.
Otherwise, a connection attempt to a remote machine was made (and a
bogus result code printed) if a local printer followed a remote one in
printcap, and you did a `lpq -a', since checkremote() falsely assumed
the printer to be a remote one.
While i was at it, removed a gratuituous newline printed in front of
the remote machine's name, thus making the output more consistent (and
better machine-parseable) now.
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?
with libc's version.
lpd: use getopt(3), err(3), add usage(), allow specification of a port #
on the command line as the documentation suggested for more than 10 years.

overflow patches that were "near" to where these operations are taking
place. The buffer overflows are from OpenBSD. The setuid/seteuid patches
are from NetBSD by way of OpenBSD (they changed them a little), at least from
my read of the tree.
This is the first of a series of OpenBSD lpr/et al merges. It (and them)
should be merged back into 2.2 and/or 2.1 (if requested) branches when they
have been shaken out in -current.

The removed files are no longer needed, they are actually labelled as
``Use only if you are not 4.4BSD''. (Yeah, the ol' crufty printcap.c
is really gone!)
Properly declare all external objects in files ending in .h, as
opposed to embed them into files ending in .c.
surprising how many trivial errors there have been... :-)
Some more cleanup is needed, but i'd like to separate the Lite2 changes
from other work, that's why this goes into a different commit.
People with serial printers should see whether i have broken the stty-
style printcap options (i hope not).
