    Rework DHCP PCB handling: Old code registered one UDP PCB per netif where 
DHCP was active and there was a special case in udp_input() for this. New 
implementation uses one PCB for all netifs and removes special case in 
    The old approach called udp_bind() on each of the PCBs, which puts them 
into udp_pcbs list. The PCBs were iterated on all non-DHCP udp_inputs() with no 
    My cleanup removes the special handling in udp.c, and uses only one DHCP 
UDP PCB to catch all DHCP messages from all netifs. The dhcp_recv function then 
checks whether ip_current_input_netif() has DHCP enabled - if not, the message 
is ignored. The PCB is only created/registered when one or more PCBs have DHCP
