Get the 'sccsid' for this to match the original lines you would
get from '-r CSRG', instead of having that sccsid as a comment.
(this is the sccsid from 1996 -- there have been many changes to
printcap.c since then!)

Take advantage of the common_source/lp.cdefs.h file to change lpr
source to use __FBSDID() for setting rcsids. Also fix the format
of 'sccsid' lines to consistently match style(9) guidelines.

Implement new printcap option of "rc" aka "remote.resend_copies".
This is a boolean option, and if it is specified in a print queue
for a remote host, it causes lpd to resend the data file for each
copy the user requested on 'lpr -#n'. This is useful for network
printers which accept lpd-style jobs, but which ignore the control
file (and thus they ignore any request for multiple copies).

Fix about 90-100 warnings one gets when trying to compile lpr&friends
with BDECFLAGS on, mainly by adding 'const' to parameters in a number
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.

Also added $FreeBSD$ line to lpc/extern.h lpc/lpc.h lptest/lptest.c

Implement new printcap options of sr= (aka stat.recv) and sr= (aka stat.send)
in lpd. Stat.recv is useful on a printserver, as something of a network
performance-monitoring tool. Stat.send is a minimal accounting record of
sorts for jobs going to tcp/ip based printers.

lpd tries to be clever and checks if RM == my_hostname.
However, it doesn't check if the remote printer name it
is sending it to is the same as the local printer name,
and so chokes 'cos "laser" is not a real printer.

Fix top-of-form bogon.

Mega lpd/lpd upgrade, part I:

- 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.
