Remove WARNS keylogin build fine with clang and gcc

Convert to usr.bin/ to LIBADD
Reduce overlinking

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

$Id$ -> $FreeBSD$

Fixed DPADD.

Don't override the (correct) default for SRCS or MAN1.

Replaced bogus Lite1 (?) Id by $Id$. The key server files were
mis-imported so it is hard to tell where they came from, but at
least in Lite2 they don't have useful Makefiles, and I rewrote
most of the Makefile.

This commit was generated by cvs2svn to compensate for changes in r26242,
which included commits to RCS files with non-trunk default branches.

Import keylogin.

This is the program used to loadsecret keys into the keyserv on the
local host.

Note: on some platforms, keylogin is automatically invoked by
/usr/bin/login. We don't have any burning need for this yet.
