Keeping list of all sockets that were sent to child process causes memory
leak and thus unacceptable (see #4587). However `server.close()` should
still work properly.
This commit introduces two options:
* child.send(socket, { track: true }) - will send socket and track its status.
You should use it when you want to receive `close` event on sent sockets.
* child.send(socket) - will send socket without tracking it status. This
performs much better, because of smaller number of RTT between master and
child.
With both of these options `server.close()` will wait for all sent
sockets to get closed.

This commit introduces two options:
* child.send(socket, { track: true }) - will send socket and track its status.
You should use it when you want `server.connections` to be a reliable
number, and receive `close` event on sent sockets.
* child.send(socket) - will send socket without tracking it status. This

child_process.fork() support sending native hander object, this patch add support for sending
net.Server and net.Socket object by converting the object to a native handle object and back
to a useful object again.
Note when sending a Socket there was emitted by a net Server object, the server.connections
property becomes null, because it is no longer possible to known when it is destroyed.
