net/portmapper: support legacy "urn:dslforum-org" portmapping services
These are functionally the same as the "urn:schemas-upnp-org" services with a few minor changes, and are still used by older devices. Support them to improve our ability to obtain an external IP on such networks. Updates #10911 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I05501fad9d6f0a3b8cf19fc95eee80e7d16cc2cfcatzkorn/jira
