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
