Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function" Add lwip_init function to regroup all modules initializations, and to provide a place to add code for task #7142 "Sanity check user-configurable values". Ports maintainers should remove direct initializations calls from their code, and add init.c in their makefiles. Note that lwip_init() function is called inside tcpip_init, but can also be used by raw api users since all calls are disabled when matching options are disabled. Also note that their is new options in opt.h, you should configure in your lwipopts.h (they are enabled per default).
