It is possible to build systemd without logind, in which case
/sys/fs/cgroup/systemd would still exist. Check for /run/systemd/seats instead,
as recommended by systemd upstream.

For details, see:

Drop the now unnecessary linking against libsystemd-daemon.

gnome-screensaver uses g_timeout_add with an integral number
of seconds as a timeout duration in various parts of the code.

These bits of code will work just as well using g_timeout_add_seconds
instead.

g_timeout_add_seconds has the advantage that it consolidates all wake
ups that happen near each other to happen at the same time, there by
creating less wake ups overall (which improves power savings)

This commit changes the applicable g_timeout_add calls to
g_timeout_add_seconds calls.

Fixes bug 682241

We don't call gdk_threads_init anyway.

gnome-shell now has its own lock screen implementation, so
gnome-screensaver is only needed in fallback mode.

commit 43ee32ed changed
the drawing area associated with each monitors screensaver
window to get realized early.

That change is seemingly causing problems for users.

This commit stops preemptively realizing the drawing areas,
and instead makes the background color settings get applied
reactively in response to realization.
