dhcp4d: reduce lease period to 20 minutes
...
This forces devices to renew the lease more often, which is nice when you want
to tie home automation behavior to DHCP lease validity.

dhcp4d: add HostnameOverride field
...
This can be used to permanently override a hostname, regardless of whether the
lease is static or not. We use a separate field because we want devices to be
able to change their hostname themselves, until we override it.

dhcp4d: don’t incorrectly _offer_ reused addresses
...
Turns out a5d9e03dd3
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: 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.
