This PR switches the windows catpowder backend from filtering all traffic to only traffic for bound ports. See also #1435 . This is better, but still problematic. Currently, there is no way to notify back from the layer4 module when a port is closed (and no longer needed, per any linger requirements). There is also no coordination with the OS re: port assignment, so ephemeral port assignment can steal ports from other programs on the system. This leaves the burden of port assignment on the client, hence the use of reprogram on bind only.
