- no more global variables, except those in the new variable "gl".
- don't pass that bus instance around. Use the singleton gl.bus.
- separate creation of ExportedObj from exporting on D-Bus.
- use enum values loaded from NM via GObject introspection.
- the visible change is that the generated D-Bus paths now start
counting at one. That is also how NetworkManager behaves, and
it looks nicer to have no zero ID for an object.
Add a test which runs nmcli against our stub NetworkManager
service and compares the output.
The output formats of nmcli are complicated and not easily understood.
For example how --mode tabular|multiline interacts with selecting
output-fields (--fields) and output modes ([default]|--terse|--pretty).
Also, there are things like `nmcli connection show --order $FIELD_SPEC`.
We need unit tests to ensure that we don't change the output
accidentally.
