Implement Anonymity Profiles for DHCP Clients, RFC 7844
This works by randomising the hardware address when carrier is down
and using this to construct a DUID LL which is used over any saved
DUID. IAID is defaulted to zero and hostname + FQDN are disabled.
Then every possible option is masked out except for essential ones.
It's possible to request options *after* anonymous option which
will enable it. This is RFC compliant and allows 100% flexability
in letting the user decide what, if any, details leek out.
This is disabled by default.
Only works on NetBSD, other OS coming shortly.
