Send the output of the -D and -L options to the standard output rather

than the standard error.

In Wireshark on Windows, create a console before doing so and destroy it
before exiting.  Don't do that in TShark or dumpcap, as those are
console-mode programs on Windows.

This should fix bug 8609 and still allow "wireshark -D" and "wireshark
-L" to work when the standard output isn't redirected.
