[ndnSIM] Exception while creating face (converting face-uri to canonical form)

[Junxiao Shi]

Hi Anil

It's NLSR's choice to always canonize a FaceUri. It doesn't have to.
ndn-cxx provides FaceUri::isCanonical() method to determine whether a
FaceUri is already canonical.

udp://192.0.2.1 is not a canonical FaceUri. See
http://redmine.named-data.net/projects/nfd/wiki/FaceMgmt "FaceUri UDP"
section.

FaceManager reports 501 "unsupported protocol" for udp4 FaceUri because
ndnSIM does not yet support UDP faces. Watch
http://redmine.named-data.net/issues/2371 for progress.

Yours, Junxiao

with "udp4" as scheme. It did not work with "udp". I am referring to this -
udp://192.0.2.1 (remote-port defaults to 6363). It did not take the default
port 6363 by default. All my neighbouring nodes are remote node in NLSR
test set up.
