The raw sockets functions are explicitly used from
inside the kernel in two places:
1. in ip_local_deliver_finish to intercept skb-s
2. in icmp_error
For this purposes many functions and even data structures,
that are naturally internal for raw protocol, are exported.
Compact the API to two functions and hide all the other
(including hash table and rwlock) inside the net/ipv4/raw.c
