net/portmapper: be smarter about selecting a UPnP device
Previously, we would select the first WANIPConnection2 (and related)
client from the root device, without any additional checks. However,
some routers expose multiple UPnP devices in various states, and simply
picking the first available one can result in attempting to perform a
portmap with a device that isn't functional.
Instead, mimic what the miniupnpc code does, and prefer devices that are
(a) reporting as Connected, and (b) have a valid external IP address.
For our use-case, we additionally prefer devices that have an external
IP address that's a public address, to increase the likelihood that we
can obtain a direct connection from peers.
Finally, we split out fetching the root device (getUPnPRootDevice) from
selecting the best service within that root device (selectBestService),
and add some extensive tests for various UPnP server behaviours.

net/portmapper: be smarter about selecting a UPnP device
Previously, we would select the first WANIPConnection2 (and related)
client from the root device, without any additional checks. However,
some routers expose multiple UPnP devices in various states, and simply
picking the first available one can result in attempting to perform a
portmap with a device that isn't functional.
Instead, mimic what the miniupnpc code does, and prefer devices that are
(a) reporting as Connected, and (b) have a valid external IP address.
For our use-case, we additionally prefer devices that have an external
IP address that's a public address, to increase the likelihood that we
can obtain a direct connection from peers.
Finally, we split out fetching the root device (getUPnPRootDevice) from
selecting the best service within that root device (selectBestService),
and add some extensive tests for various UPnP server behaviours.

net/portmapper: be smarter about selecting a UPnP device
Previously, we would select the first WANIPConnection2 (and related)
client from the root device, without any additional checks. However,
some routers expose multiple UPnP devices in various states, and simply
picking the first available one can result in attempting to perform a
portmap with a device that isn't functional.
Instead, mimic what the miniupnpc code does, and prefer devices that are
(a) reporting as Connected, and (b) have a valid external IP address.
For our use-case, we additionally prefer devices that have an external
IP address that's a public address, to increase the likelihood that we
can obtain a direct connection from peers.
Finally, we split out fetching the root device (getUPnPRootDevice) from
selecting the best service within that root device (selectBestService),
and add some extensive tests for various UPnP server behaviours.
