Let xfpm control X11's screensaver extension FIXME: dbus_init in power.c resets the configured values if xfpm restarts

Some keyboard brightness controllers have different ranges for levels.
Some have a few discreet values. Others are more like a percent. This
change uses a step based on the maximum level. If less than 20, use 1.
Else, divide by 20.

This logic is the same as used in gnome-settings-daemon. It comes from
the BRIGHTNESS_STEP_AMOUND macro in plugins/power/gpm-common.h.

This loweres the minimum upower version to support FreeBSD 10 out
of the box and fixes a couple other issues. The get_string_sysctl
function came from:
http://cgit.freedesktop.org/upower/tree/src/freebsd/up-util.c

Xfpm requires the UPOWER_ENABLE_DEPRECATED symbol to be present
for suspend/hibernate to still work on upower versions 0.9.8 thru
0.9.23. Adding it for later versions of upower won't do anything,
so there's no harm in just adding it.
Thanks to Samuli Suominen for reporting and finding the correct
fix for this.

With this patch xfpm will cache the brightness level before going
to sleep and set it back to that level after resuming from sleep.

The configure.ac.in script uses AC_CHECK_HEADERS for a ton of
things but the source files don't use those conditionals. This
patch adds those. This should fix building on GNU/Hurd.

dpms depended on power which depended on dpms which depended on
power which ... Break this loop by making power tell dpms directly
when it should be inhibited (presentation mode) and when it goes
on/off battery. This fixes at least one known xfpm startup issue.

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.

UPower dropped support for managing power. To continue to support
suspend and hibernate we'll add those functions into xfpm while
borrowing the helper code from xfce4-session.

This patch now pops up a dialog when locking the screen fails
either from a lock on lid-close or when going to suspend. If from
suspend it will allow the user to choose wether to continue with
the suspend operation.

The tip pointer could be used uninitialized when the device state
is unknown. Also tooltips are now shown for all device types rather
than just UPS and battery (i.e. for the mouse/keyboard icons). This
should prevent some confustion over what the other icons represent.

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

An xfconf and settings option has been added so the user can disable
sending network manager to sleep.

With /xfce4-power-manager/change-brightness-on-key-events=false, the
level variable is used uninitialized and the popup's level gauge is
wrong. Slight Code reformatting included, to avoid duplicating most
of the code.  (Rebased version of a patch I wrote a year ago)

They are only mirroring UpDeviceState and UpDeviceKind
from libupower-glib anyway.

* port most of the upower interfaces to upower-glib
* conditionalize stuff that has been deprecated in upower >= 0.99.0
* suspend / hibernate is handled by systemd/logind
* if upower is >= 0.99.0 and logind is not running, log errors
  (as functionality will be missing)

This patch does runtime checks to see if we can use logind for
suspend/resume same as poweroff/reboot. There's still full support
for ConsoleKit.

Point to the online docs for xfpm's help. This also fixes it where
the help button was causing the preferences dialog to quit. Now
xfpm will also display the help page when plugged into the settings
dialog. This patch removes the old local docs as well.

When xfpm changes it's lock-screen setting, it will also attempt
to update xfce4-session. Additionally, xfpm will watch session's
lock-screen setting and update its own. This way there is one
single setting for both programs in the future, however xfpm will
continue to function stand-alone.

my bluetooth mouse always shows up as a second battery which is not too
useful -- ignore devices starting with "hid-"

a bluetooth mouse's battery might not have any Energy* properties (all
zero), but a Percentage property, so it might be useful to show that.

I have enhanced xfce4-power-manager to support backlit keyboard brightness
control through keyboard brightness keys. It uses
org.freedesktop.UPower.KbdBacklight interface for increasing or decreasing
the keyboard backlight brightness and binds with keys
XF86XK_KbdBrightnessUp and XF86XK_KbdBrightnessDown.

This feature is useful when the firmware does not handle the keyboard
brightness control automatically. For example MacBook Pro leaves it to the
OS to control the keyboard brightness through special keys. With this
change, I can light up the keyboard on MacBook Pro and control its
brightness through the special keys.

I have also tested this on Lenovo X1 Carbon where the keyboard brightness
is automatically handled by the firmware and this enhancement steps aside
without interfering.

xfpm_battery_refresh_icon incorrectly adds an additional dash to
the icon prefix when the device is not a battery or a ups.

Additionally, this patch correctly shows the icon when the device
reports that it is charging.

This patch only combines the patches submitted by
Daniel Schubert and Dean Montgomery.
