Link local interfaces don't have subnet.. don't create access-control statement

Selecting link local interface for unbound causes invalid access-control
statement in unbound config since link local address doesn't have
subnet.

fix IPv6 static routes, is_ipaddrv6 returns true for strings including a
CIDR mask, which then ended up broken.

Change our default resolv-retry back to OpenVPN's default. Changing this
didn't help the ticket where it was intended to help, which was later
fixed differently. This change in defaults is problematic in a lot of
scenarios, go back to the way things were before. Ticket #3894

Merge pull request #1357 from DasTestament/patch-1

reload Unbound here, fixes some instances of PD-assigned v6 IPs missing from unbound.conf

If get_interface_ip(v6) is passed an IP, return the IP.

Properly set up interface binding for v6 link local IPs. Ticket #4021

except had to comment out the fix for now because of #4062 to avoid config breakage.

Preserve exit code lost from s/exit/return/

Cleanup whitespace.

Remove exit from as much as possible backend code

Comment out copy paste of v4 code. No need to delete arp entries on v6.
