Title: OpenFlow 1.0 IP addr wildcards

support for the IP address wildcards in OpenFlow 1.0's NW_SRC and NW_DST match fields.

our fork of NetCore uses this to support masking those fields in a match using a new "WildcardPartial" type. with this, we are able to implement a Layer 3 (IP) router.

thanks!
