* netif.h/.c, nd6.c: task #13729: Convert netif addresses (IPv4 & IPv6) to
ip_addr_t (so they can be used without conversion/temporary storage)
2015-09-08: Dirk Ziegelmeier
* snmp: Separate mib2 counter/table callbacks from snmp agent. This both cleans
up the code and should allow integration of a 3rd party agent/mib2. Simple
