- Fix the DPMS detection by adding correct lib/cflags on Xext AC_CHECK_LIB, so -lXext is correctly added on link time (taken from xfwm4)
- Also uses XDT_CHECK_LIBX11_REQUIRE to detect X11

Move the screensaver inhibit, heartbeat, and lock code to its own
set of files we can easily share with xfce4-session. Use the
screensaver's dbus API if it supports it for inhibit and lock
calls. Otherwise, use the heartbeat-command and LockCommand
from xfpm and xfsm if available. Finally, for the lock function,
fallback to trying xdg-screensaver, xflock4, and xscreensaver-command
in that order.

Instead of using XTestFakeKeyEvent, attempt to contact whatever
screensaver is running via its dbus interface. Failing that,
a /xfce4-power-manager/heartbeat-command xfconf property will be
executed every 30 seconds to keep the screensaver from
launching. This way xscreensaver, xdg-screensaver, caffeine or
a similar tool can be used.

Use the XScreenSaverSuspend and XTestFakeKeyEvent calls to suspend
the screensaver when we're in presentation mode or something has
requested an inhibit lock. This tries several different ways of
getting the screensaver to stop running since there's no standard
way listed on: http://www.freedesktop.org/wiki/Specifications/

Per the 4.14 roadmap, Upower 0.99 is the new minimum so drop support
for older versions.
