Ping uses raw sockets? I really doubt that, if not, why do we have any 
ICMP implementation?


Because providing an interface for a superset of all the ICMP userland
tools is easily more work than raw sockets. The kernel ICMP implements
all the kernel cares about, not more.
Then all userland tools implement the rest for themselfes? where's the 
rest of the ICMP stored?
