It seems to be possible for a user to back out of a screen before
receiving the "dialog completed" callback on Android, in which case
things pointed to by the callback might be gone.
In this case, it's better to simply not call the callback, rather than
crashing.
This is accomplished by assigning "Tokens" to screens that cause
requests, and in ~Screen, invalidate any pending requests belonging to
that token.
Seems the game might not handle the case of confirm button being set to
cross properly, so force it to circle if this game is running.
Fixes#15663 (hopefully..)
Still left some ifdefs because of System_InputBoxGetString(), but
hopefully we can move away from them. Some devices (like SDL) may only
optionally have a keyboard, so it's a runtime check.
