Unbound: bug fix odhcpd and add auto adblock

Bug fix dhcp4_slaac6 option was adding to all IP6 routes.
Filtering was added to this process to only include addresses
served from "this dhcp interface."

adblock 2.3.0 file output is now detected and automatically
integrated into Unbound local-zones. adblock deposites its
block site zone-files into /var/lib/unbound. If this is not
desired, then disable adblock or reconfigure to avoid Unbound.
