tipc: add sock dump to new netlink api
Add TIPC_NL_SOCK_GET command to the new tipc netlink API.
This command supports dumping of all available sockets with their
associated connection or publication(s). It could be extended to reply
with a single socket if the NLM_F_DUMP isn't set.
The information about a socket includes reference, address, connection
information / publication information.
Netlink logical layout of response message:
-> socket
-> reference
-> address
[
-> connection
-> node
-> socket
[
-> connected flag
-> type
-> instance
]
]
[
-> publication flag
]
