input_server must be notified about shutdown

[marcusoverhagen]

input server must be notified that the system is beeing shut down, as it has to notify BInputServerDevice::SystemShuttingDown()

BeBook:

Tells the object that the Input Server is in the process of shutting down. Unless something interrupts the shutdown, this notification will be followed by a Stop() and delete, thus you don't have to do much from this function (other than note that the end is near).

Please suggest a message protocol. And add the message codes to some private header (headers/private/app/RegistrarDefs.h? Or a new header?).

Perhaps registrar should quit input_server after all other applications have quit.

I don't see a valid reason for keeping input_server running after shutdown.

Having the "Reboot" button after the system has been shut down isn't very important in my opinion.

With APM or ACPI working, the system will power off after shutdown, so the "Reboot" button would only be visible/useful on hardware where both APM and ACPI is broken.

Ingo, would be it ok to have the registrar send a warning message (SYSTEM_SHUTTING_DOWN) to vital apps instead of ignoring them ?

[bonefish]

I suppose instead of a special message we can just send B_QUIT_REQUESTED to the "vital" apps after all other apps have been quit. If you need it now, please feel free to adjust the shutdown code (I've switched my working dirs to my branch at the moment).

Fixed as of hrev19289. The input server is now notified of the shutdown.
