rc_pre() functions are returning correctly. This change
also simplyfies the changes because false || return 1 can be replaced
with false if that's the last call. thanks halex@!

From now on rc(8) is going to call these scripts to start them up on boot
in the same order than before.
In addition the inetd and rwhod variables in rc.conf are deprecated so that
inetd_flags and rwhod_flags should be used. The old flags are still going
to be used for some time to allow users to switch.
There are more rc modifications to come later so let's put this in so
we can base more work on this.
It is important to mention that you can still keep using rc.local just
like the way you did before, and we have no intention to remove that either.
I'd also like to thank ajacoutot@, halex@, sthen@ and schwarze@ for working
on this with me.
