With UPower < .99 this patch will make the battery panel icon
dynamic by displaying the ups or battery device with the highest
percentage. This patch also cleans up a couple small issues with
the last two patches (unused function and variable).

When upower reports unknown there is no useful information for the
device so present that to the user rather than a 0% battery level.

Upower 0.99 supports a composite display device that represents
the state of the computer. When that device type is around we will
use it to determine the panel icon, update the tooltip, and replace
the UP_DEVICE_KIND_LINE_POWER in the menu since it would be redundant.

The left click menu now displays the devices and their status at
the time of the menu's creation.

Rather than using a custom window migrate to custom items in a
GtkMenu. To that end, change from a GtkTreeView to GList internally.

Also put more trace/dbg messages in place so it's easy to track
these issues when upower breaks itself again in the future.

Dynamically changing the icon in the panel itself looks horrible.
Revert and improve it later.

This patch moves some code around, mostly putting shared stuff into
power-common inside common/. It also creates a new plugin to monitor
all the batteries in one icon on the panel rather than multiple icons
inside the system tray. It also removes the power-info application
as that will be moved inside the newly reworked settings dialog.

Make changes so that xfpm will compile in --enable-debug=full with
the nick/xfce4-dev-tools deprecated+seal branch.

Update autotools, fix whitespace issue, change how the version
string is presented with make distcheck, fix --disable-dpms so
it will actually compile, and update the minimum versions for
the 4.12 roadmap.

Updates from the per-4.8 panel registration method. Also updates
the gtk about function for the new field and updates the makefile
for the plugin.

The "Backlight" RandR property is a 32-bit integer. This means that the int32 (gint32) type should be used to represent brightness levels. The attached patch does nothing else than changing the brightness level representation from glong to gint32. This fixes the screen auto-dimming issue and brightness panel plugin issue.
