fhandler_socket::dup

[Pierre A. Humblet]

Corinna,

Here is a patch to have fhandler_socket::dup return success
or failure (related to the problem seen by Jason Tishler).

	* fhandler_socket.cc (fhandler_socket::fixup_after_fork):
	Set io_handle to INVALID_SOCKET in case of failure.
	(fhandler_socket::dup): Return 0 iff the io_handle is valid.
