opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES, ETHARP_TRUST_IP_MAC, review SO_REUSE).
Also include directly tcp.h in sockets.h to improve application independancy from ip stack (avoid to include directly in application the "unknown" tcp.h if you need options like TCP_NODELAY and TCP_KEEPALIVE in application.
