When rematching, some users have a convention that e.g. lowest scoring
player in the "parent" game goes first. So allow that, providing the
choice on each rematch until a default has been chosen. Support
changing that default in a new prefs setting.
The place I chose to enforce the order was on the host as invitees are
registering and being assigned slots. But by then there's no longer
any connection to the game that was rematched, e.g. to use its
scores. So during the rematched game creation process I create and
store with the new game the necessary ordering information. For the
3-and-4 device case, it was also necessary to tweak the information
about other guests that the host sends guests (added during earlier
work on rematching.)
I don't know why, but in my tests the relay seems to be delivering
messages to the wrong device. The linux device detects this. It used to
assert, but now just drops the message. If this is happening on Android
it might be why I'm seeing crashes...
My version of curses doesn't seem to have its own SIGWINCH handler that
does the right thing, so use a pipe to let my handler signal to have
work done outside the interrupt context (when window resizing etc. that
might call malloc() isn't safe.)
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.
