dhcp4d: fix IP address comparison
...
AFAICT, this wasn’t actually a bug: canLease performs the correct check.

dhcp4d: don’t incorrectly _offer_ reused addresses
...
Turns out a5d9e03dd3212f7f0c11dd856b308a16a58a3cdf was not entirely sufficient:
even though reused addresses would not be handed out anymore, they would still
be offered, which results in the client not being able to obtain an address.

dhcp4d: respect broadcast bit
...
Mac’s Internet Recovery DHCP client requires broadcast responses and will ignore
unicast responses outright.

dhcp4d: send replies as unicast using raw sockets
...
Preferring unicast over multicast (which hogs a lot of airtime on WiFi networks)
is a best practice.
Some device/access point vendor combinations even seem to entirely eat (some?)
broadcast traffic (sometimes), e.g. my Apple iPhone SE/Ubiquiti UAP-AC-HD, so
that using unicast is required for reliable WiFi.

dhcp4d: always set broadcast flag for DHCPOFFERs
...
We always broadcast them, so we should signal that.
