dhcpd: mac-based dynamic ip address picking
themiron at mail.ru

The idea of this patch taken from dnsmasq:
* the same ip address offering for clients with expired lease (almost
always) without any additional state saving
* prevent the same ip address allocation for different interfaces of the
dumb Windows dhcp-client (win7) ACKs same-subnet IP address, no matter if it
was previously assigned to the other interfaces, and can't assign it to the
current one, even if that different interface is down.
mac-based allocation makes this "endless discover-offer-request-ack loop"
issue almost impossible.
