In recent kernels, hiddev* devices now have class "usbmisc", rather
than "usb" (see http://www.spinics.net/lists/linux-usb/msg62276.html).
This change translates into a change in SUBSYSTEM matching for hiddev*
devices. This fix addresses this for recent kernels while retaining
existing behavior. For reference, here is an attribute-walk for a
CyberPower CPS 1500C on kernel 3.7.0:
[Ubuntu bug #1091702: udev rules fail to match hid devices with new kernels]
udevadm info --attribute-walk --path=/devices/pci0000:00/0000:00:1d.2/usb4/4-1/4-1:1.0/usbmisc/hiddev0
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

When running under systemd, call into systemd for suspend and
hibernate instead of pm-utils. To capture resume events, install
a small script that gets executed by systemd after resume and
sends a dbus signal back to upower.
To make this work, the upower backends gain a new signal, ::resuming,
that they can optionally emit to signal that a resume happened.
Backends opt in to this by returning TRUE from up_backend_emits_resuming().
In this case, upower doesn't assume the sleep command to block until
resume, but instead waits for the ::resuming signal from the backend.
The only backend that uses this mechanism is the linux backend when
built with systemd support.

Fix NULL pointer comparison in up_device_supply_coldplug(). This caused
(lt-upowerd:5754): GLib-CRITICAL **: g_ascii_strcasecmp: assertion `s1 != NULL' failed
when a device does not have a "scope" sysfs attribute, and erroneously
considering that device to not power the system.

Crash the daemon on any CRITICAL message, and also set WARNING and CRITICAL
messages to be fatal on the client side. On the server side we might have some
legitimate warnings, such as failing to load the config file from
/usr/local/etc (if you build a tree without passing correct --sysconfdir
options, etc.).
This exposes the current CRITICAL the daemon raises at startup. As with that
the daemon never starts up, fix the "wait for the daemon" loop to time out
after 10 seconds.
CancelRequest() never worked because the method signature in D-Bus
introspection data didn't match the actual function signature.
Since the 'type' parameter isn't needed by the implementation (cookies
are unique across all requests, not just requests of a certain type),
we drop it from the public API. This makes it easier for clients to
use the API as they only have to remember the cookie, not both cookie
and type. Since it never worked in the first place, there are no
backwards compatibility issues.

up_qos_init() registers a destroyer callback for the qos item array,
so the current item will be gone after the calls to
g_ptr_array_remove(). By storing the item kind in a local variable we
can pass it to up_qos_latency_perhaps_changed() later. Delaying the
removal from the array is not an option as
up_qos_latency_perhaps_changed() scans that array to re-evaluate the
target latency.

The type of the 'value' parameter of the LatencyChanged signal is
integer, not boolean. Fixing this causes the signal to actually be
emitted.

Some HID devices with batteries (like bluetooth keyboards) have been creating
power supply devices in sysfs since Linux 3.3.
UPower thinks that they are system devices and shuts down the system if they
get low. This is bad.
This is fixed in Linux 3.4, where there is a new 'scope' file that defines if
the device is powering the system.
Helpfully ACPI batteries don't populate the scope value, but soon will.
Add support for the scope attribute now, and default to system devices if it's
missing. Note, you need to be running a 3.4 kernel or a 3.3 with the patch
backported for this to work.

This reverts commit 14761c09d2.
The real reason for the failure is that Makefile.am calls the script with
"python" which is Python 2, but we need Python 3.
unittest.TestCase unfortunately does not have any public API to check whether
a test case succeeded, so we use the private self._outcomeForDoCleanups. This
does not seem to exist every time, so avoid a crash if it doesn't.
According to Anton Vorontsov (Linux power supply maintainer) power
supplies should not export a present property when they are not
hotpluggable and users of the properties should handle supplies
without present-property as always present.
This patch implements this feature using an additional
sysfs_file_exists call before sysfs_get_bool.

Spotted when running regression tests in KVM. There, initializing a HID device
causes a "could not initialize libusb: -99" warning, but the device is created
nevertheless. Do not crash in _finalize() by trying to call libusb_exit(NULL).
For hardware that has no rate data we use the differences in charge over a time
period to work out the effective rate. Using linear regression this estimation
is much more realistic.
To do this, introduce a simple circular buffer and use an index to calculate
the rate on each update.
