Mark variables static where possible and place the uid/euid variables in
lp.h, so that we can compile-time enforce that these variables have the
same type.
programs, minor Makefile changes are needed to find lp.cdefs.h.
For lpf.c, the 'sccsid' line is formatted to match style(9), and
a 'From:' is removed so the sccsid returns to what it was back
in the days of '-r CSRG' (1994).

MFC after: 15 days
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

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
