Pavel Emelyanov f65c1b534b sock_diag: Generalize requests cookies managements
The sk address is used as a cookie between dump/get_exact calls.
It will be required for unix socket sdumping, so move it from
inet_diag to sock_diag.

Pavel Emelyanov aec8dc62f6 sock_diag: Fix module netlink aliases
I've made a mistake when fixing the sock_/inet_diag aliases :(

1. The sock_diag layer should request the family-based alias,
   not just the IPPROTO_IP one;
2. The inet_diag layer should request for AF_INET+protocol alias,
   not just the protocol one.

Thus fix this.

Pavel Emelyanov b6d640c228 udp_diag: Implement the dump-all functionality
Do the same as TCP does -- iterate the given udp_table, filter
sockets with bytecode and dump sockets into reply message.

The same filtering as for TCP applies, though only some of the
state bits really matter.

Pavel Emelyanov a925aa00a5 udp_diag: Implement the get_exact dumping functionality
Do the same as TCP does -- lookup a socket in the given udp_table,
check cookie, fill the reply message with existing inet socket dumping
helper and send one back.

Pavel Emelyanov 52b7c59bc3 udp_diag: Basic skeleton
Introduce the transport level diag handler module for UDP (and UDP-lite)
sockets and register (empty for now) callbacks in the inet_diag module.
