>Description:
	A couple of weeks ago there was a discussion on /etc/rc vs
	/etc/rc.?d/*, amongst other things

	At that time I suggested that whatever decision is made, the
	concept of having /etc/rc source /etc/rc.conf for information,
	rather than using
	/etc/{hostname.*,netstart,myname,mygate,defaultdomain,ifaliases}
	I got a lot of positive replies on this, so here's the
	changes.

>How-To-Repeat:
	Look at
	    /etc/{rc,hostname.*,netstart,myname,mygate,defaultdomain,ifaliases}
	Decide that it's a crock.

>Fix:

	Apply this diff, rename rc.conf.eg to rc.conf, edit
	appropriately, and reboot.

	After the changes, the following files are superfluous and can
	be removed from the src tree and /etc:
		ifaliases
		myname
		mygate
		defaultdomain
		hostname.*
		netstart

	I've tested this fairly well, including the interface alias code.
	The only thing I haven't tested is the 'destination_addr'
	change, but it's trivial, and you can see from observation
	that it should work.
