[task] dbus based screensaver

[Stuart Auchterlonie]

Task to track replacing the XDPMS based screensaver with a DBUS based approach. The DPMS approach no longer seems to work at all

[Stuart Auchterlonie]

I've added a test program which will inhibit the screensaver via dbus.

It works so far on f20/f21 with Qt4 and Qt5. Tests on other platforms wanted

Fix lirc being ignored after dbus screen saver changes.

If the Screensaver is Asleep() we ignore all keypresses
generated via the remote. This is clearly so that a button
pressed on the remote while the screen is asleep only wakes
up the screen, rather than triggering an action.

This swaps the logic around in the dbus screensaver so that
it satisfies the Asleep() check.

We may need to revist this in the future if we find that
when using the dbus screensaver we are not ignoring the
remote keypress which is used to bring us out of screensave.

Separate the ScreenSaver? base class from the ScreenSaverController?.

This is a preliminary step to allow multiple screen saver control
methods to be utilized at the same time.

Re-Enable screensaver-x11 after the dbus screensaver support was added.

This now utilizes the dbus screensaver first, and then the previously
existing screensaver methods. This should resolve the issues seen by
those using only DPMS or xscreensaver.

This is now all completed. Closing
