After going through patch 2/2, I realized that maintaining the "return
-1 when no prefix or netmask or address is specified" rule in this new
function will prevent someone from declaring a default route on a network:

     <route gateway='1.2.3.4'/>

because this will return -1. I checked all the callers of the original
function, and they all are already guaranteed to have a valid address,
so we can safely change the default case of this function to return 0.

I'm going to make that change and push this patch so that you don't have
to resubmit it with the new spin of 2/2 that I'm requesting.
