Make face-up tile picker util method return void and add mechanism for
passing in selected tiles asynchronously, as has been done recently with
the rest of the once-blocking util callbacks. Works perfectly in the gtk
case. Likely crashes in curses (if picking face-up option is on.) In
java all the callbacks are there but rather than put up a UI we pretend
the user says "pick 'em for me" each time. Putting up a UI is next.
Board renders, but only when touched. Tray and scoreboard skipped for
now. Lots of changed still to go, and some asserts added where I didn't
want to stop to solve a compile problem.
to enable it for a game yet). In common code, break pick tile utils
method in two, one for blank and the other for tray tiles. In java,
implement dialog for picking the tiles. Works, though is a bit clumsy
to have the dialog come and go after every pick. Better would be a
dialog that stays up and accumulates picks -- but it'd have to know to
reduce the set of tile choices as letters are chosen. This'll do for
now.
deal with the output by removing params where possible and elsewhere
by adding XP_UNUSED macro wrapping __attribute__((unused)). There
should be NO change in function in spite of the large number of files.
