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.

Under Linux, regardless of the exit code of /usr/bin/pm-is-supported, it will
always set CanSuspend and CanHibernate to true due to a logic error in
up_backend_supports_sleep_state in src/linux/up-backend.c: The 'ret' variable
is re-used for the return code without being re-initialized to false after the
call to g_spawn_command_line_sync.

Files might not be there, or in the case of cross-compilation, they most
definitely won't be there (and if they are, they are not the ones you
should be looking for). Instead use the autoconf-defined $host variable to
identify for what system we're building for.

So far the test cases only covered drivers which reported energy (µWh). Add
checks that the Energy* properties are correct, and add a test case for drivers
which report charge (µAh).
This allows session power managers to do different actions depending on whether the user
is suspending or hibernating. This allows the session policy agent to poke other things
(for instance, the screensaver) even if another process initiated the sleep.
This is based on a patch from Phillip Susi <psusi@cfl.rr.com>, many thanks.
In restricted environments such as package builds we do not have a system D-BUS
running. In that case, don't just fail, but use the recently introduced
up_daemon_set_bus_type() to run tests on the session D-BUS instead. Run
up-self-tests under dbus-launch for this if available.
Skip tests which need polkit if there is no system D-BUS, as we can't sensibly
run this on the session bus.
With nested Makefiles we can't depend on a generated file in a different
directory (breaks "make clean && make check"). Thus move the call of the Linux
integration test suite into src/Makefile.am, and only run it if we build the
Linux backend.
