Debugger: Change user interface quit and ask user semantics
* UserInterface::SynchronouslyAskUser() is now allowed to return -1 to indicate that the user cannot be asked at this point for whatever reason. The caller needs to handle that case. * UserInterfaceListener::UserInterfaceQuitRequested(): Add new parameter "quitOption" to specify what is supposed to happen. The previous behavior (ask user) is only one of the options. The others are to kill the debugged team or to resume it.
