Eric House 2629c07256 Address problem with devids (e.g. GCM): until now when you got a new
devid you tossed your relayID and reregistered.  Which meant any
existing messages meant for your relayID were orphaned, and any open
games didn't know who they belonged to until you reconnected to them
with your new relayID.  So: modify the UDP protocol (though not on
Android yet) to include both relayID and devid with registration, with
one or the other an empty string if not present or not changed from
earlier.  I can't fix existing clients that are dropping their
relayIDs, but when one does a re-connect without a relayID I can look
it up from the existing game record, then reuse it rather than issue a
new one.  Better than nothing -- and that protocol will be obsolete
soon anyway.
