Segregate ipv4 and ipv6. Allow jail creation without IP address. Modify set and get options to use new ipv4/ipv6 configuration options. Allow bridge and default router configuration for ipv4/ipv6. Add -v switch to list option so that all jail information can be displayed. The only issue found with all of this at this point is if no IPv(4|6) address is configured, an epair device will still be created.
