[RAW]: Add raw_hashinfo member on struct proto.
Sorry for the patch sequence confusion :| but I found that the similar
thing can be done for raw sockets easily too late.
Expand the proto.h union with the raw_hashinfo member and use it in
raw_prot and rawv6_prot. This allows to drop the protocol specific
versions of hash and unhash callbacks.
