internet: need a socket for ICMP
The Ping applications are using a SOCK_RAW, while thy should use socket(AF_INET, SOCK_DGRAM, IPPROTO_ICMP)
or socket(AF_INET6, SOCK_DGRAM, IPPROTO_ICMPV6)
, and we do not have them.
This issue is to create them, and perhaps change the actual (incorrect) use of RAW sockets where they're currently used.
This will basically create the building block to fix #809
