Phones are suspended most of the time so they are not awake for > 20s
to allow UPower to take action when battery is critical.
Add an interface to take and release inhibitor locks which
prevent the device from suspending to allow UPower to execute
the critical power action.
Include $(top_builddir) when building so that we can find the newly
generated D-Bus helper files. Note that, because we ship generated files
in the tarball, we'll also need to include $(top_srcdir).
This patch adds support for using ConsoleKit2's DBUS API to
implement the critical action for FreeBSD and OpenBSD. It does so
by creating a common backend file both can use to implement the
API calls.
