libsystemd-dhcp: Handle T1 Renewing timeout
Expiration of T1 timeout takes the client to the Rebinding state, where it attempts to renew its lease. Start by opening a DCHP unicast socket as there now is a proper IP address set. Compute the resend timer as half of the remaining time down to a minimum of 60 seconds (RFC2131). Modify DHCP Request sending to send only UDP DHCP data when unicasting. Also modify DHCP Ack/Nak receiving such that the client_receive_ack() takes care of using either the full IP, UDP, DHCP packet or only the DHCP payload depending whether the client is in Requesting or Renewing state. Finally always report DHCP_EVENT_IP_ACQUIRE from Requesting state and only DHCP_EVENT_IP_CHANGE if the IP address was modified when the lease was renewed.
