Attached is a patch that enables this.
If started with -4 $int, or -6 $int, any subsequent call to dhcpcd to 
rebind, reconfigure or exit must contain the same restrictive flags.
This is now documented. I don't really want to add too much code for 
this, as it's entirely an operator decision and we should (although 
probably incorrectly) the operator has a brain.

Although `dhcpcd -x $int` would stop -4 and -6 in the perfect world, 
dhcpcd doesn't check for existing per interface instances when starting 
in master mode so I'm not too bothered right now.

Everyone happy with this?
