resolv.rb: close socket
* lib/resolv.rb (UnconnectedUDP#lazy_initialize): store new
sockets before binding, so the sockets get closed when the
requester is closing.
* lib/resolv.rb (ConnectedUDP#lazy_initialize): ditto.
* lib/resolv.rb (UnconnectedUDP#close): synchronize to get rid of
race condition.
* lib/resolv.rb (ConnectedUDP#close): ditto.
