with the following changes:
- Allow configurations to be marked as Deprecated and Acivtated
- Harden resolvconf lock detection
If using resolvconf, dhcpcd-9.4.0 will require a resolvconf implementation
which supports the Deprecate option-C and Activate option-c
if the OS supports the concept of IP persistance.
Currently this is Linux (wireless roaming) and NetBSD-8 (IP persistance).
If there is no resolvconf then it works fine.
If there is a resolvconf which lacks these options then the 20-resolv.conf
hook script will warn about an invalid option, but will otherwise work.
In this instance the DNS information cannot be Deprecated and may not
be optimal for multi-homed hosts.
