more sensible/understandable. 'from'->'from_host' 'host'->'local_host'
'fromb'->'frombuf' 'fromhost'->'origin_host' and a local-variable
named 'host'->'hostbuf'. This fixes some compile-time warnings about
local variables shadowing global variables.
Other than renaming variables, the only actual code changes are to call
strlcpy() instead of strncpy() when setting those (renamed) variables,
and that 'from_ip' is now a strdup()-created buffer instead of being a
static buffer compiled in as 1025 bytes.

of routine declarations. While I'm at it, ANSI-fy all of the routine
declarations. The resulting object code is exactly the same after
this update as before it, with the exception of one unavoidable
change to lpd.o on freebsd/alpha.

sorts for jobs going to tcp/ip based printers.

was having its last element zero'd. It turns out not to be a security
hole or to have any real effect on the code because 'from' was previously
pointing to a buffer of the same size as 'fromb', and the last
element in fromb is already 0 anyway due to the use of sizeof(fromb)-1
in the strncpy() call. But I'm not pressing my luck so only the type-o
is being fixed.
- Get rid of a lot of the static variables which were shared by
many routines and programs in the suite.
- Create an abstract interface to the printcap database, so that
other retrieval and iteration mechanisms could be developed
(e.g., YP, Hesiod, or automatic retrieval from a trusted server).
- Give each capability a human-readable name in addition to the historic
two-character one.
- Otherwise generally clean up a lot of dark corners. Many still remain.
- When submitting jobs, use the official login name record (from getlogin())
if there is one, rather than reverse-mapping the uid.

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.
