This is meant to replace the relay eventually, but for now it's a new
option, like BT or SMS, to be chosen. Protocol is handled in common/
code for the first time, meaning that linux and android interact without
the need to keep two platforms in sync. Linux uses lib-mosquitto, and
Android uses eclipse's Paho client (the generic java version, not the
one that uses four-year-old Service patterns and so crashes for SDK >=
26.)
Lots of changes adding a games-list view to the app from which you
create new games, open and delete existing ones, etc. There's still
plenty that's unimplemented, but it's already more useful for testing
and development. Which is the point.
I've long wanted common code and state that outlast a single game. The
smsproto stuff is a step in that direction, but this file will be a
place for anything new. Starting, perhaps, with a mapping of deviceID ->
addressInfo (e.g. BT name or SMS number of opponent device) that will
let me stop duplicating that stuff in every game's comms state. We'll
see. It's guarded by a compile-time flag so I can play with in on the
Linux version until ready.
