Python-dbusmock

- upower template: Set Energy and EnergyFull properties.

- In the logging of mock method calls, log the arguments as well.
- Fix race condition in waiting for mock to get online on the bus, by avoiding
triggering D-Bus service activation with system-installed services.
- Add "notification_daemon" mock template.

- tests: Suppress "nmcli and NetworkManager versions don't match" warning.
- networkmanager template: Add DeviceState enum for easier specification of
states. Thanks Alberto Ruiz.
- Fix deprecation warnings with PyGObject 3.7.x.

- Fix tests to skip instead of fail if NetworkManager or upower are not
installed.

- Turn dbusmock from a module into a package. This is transparent for API
users, but necessary for adding future subpackages and also makes the code
more maintainable.
- Run pyflakes and pep8 during test suite, if available.
- Add support for templates: You can now call AddTemplate() on the
org.freedesktop.DBus.Mock interface to load a template into the mock, or in
Python, start a server process with loading a template with
DBusTestCase.spawn_server_template(). Templates set up the common structure
of these services (their main objects, properties, and methods) so that you
do not need to carry around this common code, and only need to set up the
particular properties and specific D-Bus objects that you need. These
templates can be parameterized for common customizations, and they can
provide additional convenience methods on the org.freedesktop.DBus.Mock
interface to provide more abstract functionality like "add a battery".
- Add a first simple "upower" template with convenience methods to add AC and
battery objects, and change tests/test_upower.py to use it.
- Add a first "networkmanager" template with convenience methods to add
Ethernet/WiFi devices and access points. Thanks Iftikhar Ahmad!
- Add symbol dbusmock.MOCK_IFACE for 'org.freedesktop.DBus.Mock'.
- Add test cases for command line invocation (python3-m dbusmock ...).

- Ship NEWS in release tarballs.
