Actually, the socket path if it's not anonymous doesn't give
a clue to which file the socket is bound to. Even if the path
is absolute, it can be unlinked and then new socket can be
bound to it.
With this NLA it's possible to check which file a particular
socket is really bound to.

The socket inode is used as a key for lookup. This is effectively
the only really unique ID of a unix socket, but using this for
search currently has one problem -- it is O(number of sockets) :(
Does it worth fixing this lookup or inventing some other ID for
unix sockets?
