* tests/nc_test_slave.c (nc_slave): Fix some of the compiler warnings. * cdl/lwip_net.cdl Changed default value of CYGNUM_LWIP_MEMP_NUM_SYS_TIMEOUT (required for DHCP).

Change tcpip_init_done() to start DHCP timers and ARP timer. Changed lwip_set_addr() to properly setup IP adress if DHCP is used. Added lwip_dhcp_init() for start of DHCP client. Removed start of ARP timer from ecosclue_init(). * src/netif/etharp.c Updated file to version of lwIP CVS.
