Prevent completely empty interface blocks.

This is meaningless in dhcpleased(8) and *not* needed to receive
leases for an interface. In fact dhcpleased(8) works just fine without
any configuration file at all.

First stab at IPv6-only preferred from RFC8925.

This lets dhcpleased(8) request "IPv6-only preferred". If the
server replies with this option dhcpleased stops and does not request
a lease and deconfigures IPv4 on the interface.

For now this is pretty much useless unless one dynamically configures
pf(4) to act as a CLAT. gelatod(8) from ports can help with this.

However, this helps me while hacking on a kernel based stateless CLAT
by moving dhcpleased out of the way while having an IPv6-mostly
network configured to compare behaviour with macOS.

According to RFC 2132 (9.14. Client identifier) a hardware type of 0
should be used when the client identifier is not a hardware address,
for example if it's just a string. It turns out that the majority of
dhcp clients (and possibly servers?) does not do this but rather
transmits the client identifier verbatim if a string is
configured. The first character becomes the hardware type.
