Message box support. This allows us to display a platform-native dialog for problems which occur early in startup (before we can show a PUI/Canvas dialog). In particular this improves feedback where FG_HOME, FG_DATA or aircraft selection is wrong, all of which happen very early in startup.

Make fatalMessageBox() end with std::abort() and declare it [[noreturn]] Many places calling fatalMessageBox() assume it doesn't return, so make it behave this way. See discussion around: https://sourceforge.net/p/flightgear/mailman/message/35766691/ for some context.

Revert commit "Make fatalMessageBox() end with std::abort() [...]" This reverts commit 9e6a3ebc6b46fc37134f50dd63fe366087cc4750 ("Make fatalMessageBox() end with std::abort() and declare it [[noreturn]]"). After reflexion, it seems better to let fatalMessageBox() return, because there is existing code that appears to be relying on this aspect to do some work after having called fatalMessageBox() (cf. main() in bootstrap.cxx). Also, the way of exiting from fatalMessageBox() after commit 9e6a3ebc6b (std::abort()) was probably too brutal for a controlled exit---as opposed to a terminate handler.
