This is better design to catching regressions and problems in a more
pin-pointed fashion. This also avoids having to restart the umockdev testbed
due to changing the environment variables with stop/start_daemon().
up-self-test.c: In function ‘up_test_history_func’:
up-self-test.c:274:2: warning: implicit declaration of function ‘rmdir’ [-Wimplicit-function-declaration]
rmdir (history_dir);
With the removal of the suspend/hibernate code, there's no longer
a need for upower to depend on polkit. This patch removes the old
polkit code.

The IsDocked property has been incorrect for a number of laptops for a
while, as it thought that laptops with hybrid graphics cards were always
docked.
The alternative would have been to use the platform/dock_station
devices, but those are only exported for ACPI docking stations.
Instead, whether an external display is attached (which isn't really
docking) should be checked in the same place where the policy depending
on the value should be applied, such as gnome-settings-daemon.

On the Lenovo A600 all-in-one, there's a HCI/HID dual-mode Broadcom
device which will try to get the battery level of the supplied
mouse and keyboard, but will usually fail to do so.
So we have a battery of type "battery" (it's not either a mouse or
a keyboard, as it's supposed to handle both) but our display device
battery code doesn't check whether those batteries are power supplies
or not, using this "empty" (0% after the check timed out) battery in
the shutdown policy.
Check better for power supply devices, not all the "battery" types
are power supply batteries, they might be non-power supply ones
from unknown device types.
In addition to build time - this increases compatibilty with OSTree,
which starts out with an empty /var.

This has 2 effects:
- we never stop polling (we used to stop polling when the
battery was marked as fully-charged, but that can happen when
the battery is discharging too)
- when in an unknown state, we will poll through the daemon,
and through our unknown poll. This isn't a problem as there'll
another 115 seconds of wait until we get to poll through the
daemon again.
To be used by all polling backends. This changes the defaults
to poll every 120 seconds when a warning level isn't reached, and
switch automatically to 30 seconds poll when the battery level is low.
For system integrators. If your firmware is helpful to user space
and automatically sends out uevent when the battery level changes
(rather than just the battery state) as on most machines,
you can enable "NoPollBatteries" in the configuration option,
and reduce power consumption from UPower and its listeners.
When the AC state changes, let the backends poll for battery changes.
They know better what's _really_ happening (whether the real state
is unknown even if they present a fully-charged battery), etc.
This is only possible because we fixed the Linux backend to poll
as it should always have.
Some batteries report energy > energy_full and a percentage ("capacity"
attribute) > 100%. Clamp these within 0 and 100% for both plausibility as well
as to avoid setting an out-of-range property which would then become 0%.

I don't think the kernel exports any numbers with a decimal
portion, but if they did, they would get the wrong values because
some locales use "," as the decimal separator, and not "." as the
kernel/C locale would.
If one battery is draining and the other one isn't, the time
to empty wouldn't be zero, but it would only match the time
to empty for the single battery.
Instead, ignore the accumulated time to empty/time to full
for multiple batteries and recalculate it.

When UPower crashes, we would never notice the battery going flat
because UPower clients aren't polling UPower, so won't autostart it.
Instead we rely on systemd to restart us when we crash. libupower-glib
also supports the client coming and going.

Update the expected warning levels to match, and add a big
fat FIXME for the test case itself. That's not how UPSes work,
or how UPower is expected to work.
