    Implement deferred closing of Windows handle-sockets.
    
    When a handle socket is in THAWING state and handle_socket_unfreeze is
    gradually passing the backlogged data on to the plug, the plug might
    suddenly turn round and close the socket in the course of handling
    plug_receive(), which means that handle_socket_unfreeze had better be
    careful not to have had everything vanish out from under it when that
    call returns. To solve this, I've added a 'deferred close' flag which
    handle_socket_unfreeze can set around its call to plug_receive, and
    handle_socket_close will detect that and not actually free the socket,
    instead leaving that for handle_socket_unfreeze to do under its own
    control.
