Follow the model of how things are done for Contiki. Set up a new WITH_LWIP_NO_SOCKET (which happens with NO_SYS = 1) and use this when setting up addresses. Add in platform specific for dtls_prng_lwip.c and lwip_platform.h Update dtls_time.[ch] to handle LWIP version of time. Code works for NO_SYS = 1 or NO_SYS = 0.
