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.
Handles case where the app receives only a subset of the SMS messages
into which a larger game-level message has been broken. Now when it
restarts and the remaining parts come in the whole can be reassembled.
Trying to separate what's game-specific from what can be app/device
specific (i.e. with a long lifespan, and available when a game isn't
open.)
Android will be broken after this commit and fixed after the next
