* init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
user-configurable values".
2007-08-29 Frédéric Bernon
* igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
igmp_start is call inside netif_add. Now, igmp initialization is in the same

- Ditto MEMP_NUM_ARP_QUEUE can be compared to the number of pbufs.
- Ditto IP_FRAG_USES_STATIC_BUF
- Ditto TCP_SND_QUEUELEN
- TCP_WND versus PBUF_POOL_SIZE*PBUF_POOL_BUFSIZE
- TCP_MSS <= TCP_WND
- We could consider ensuring that the number of pbufs exceed MEMP_NUM_NETBUF+MEMP_NUM_ARP_QUEUE+TCP_SND_QUEUELEN
- Perhaps do range checking on some values? */
