/* Game starts out in BEGIN.  If the server expects other players, it goes
 * into XWSTATE_WAITING_ALL_REG.  Likewise goes any client waiting to hear
 * from the server after sending off its info.  A stand-alone game (server)
 * goes immediately from BEGIN to WAITING_INFO.
 *
 * When a device gets tiles for all players (which happens in a single
 * message where there's communication involved) it moves to INTURN (either
 * ONDEVICE or OFFDEVICE).  ONDEVICE changes to WAITING_INFO when the device
 * sends its move to the server; OFFDEVICE changes to ONDEVICE if a
 * notification that a move's been made is received and it's now a local
 * player's turn; otherwise that notification may arrive with no change in
 * XW_State (but a change in whose turn it is.)

After a move is made (current player's device
 * sends move
