port to libqofono

[simonschmeisser]

this is a port from ofono-qt to qofono which is actively maintained by jolla, implements #2

this includes #5 for now, will rebase once that has been merged

open todos are marked with "todo porting" in the code:

• compiles without ofono-qt
• error handling for sendMessage
• error handling for calls
• unit tests
• some more

[simonschmeisser]

porting those unit tests feels strange as I need to copy paste a specific version of the qofono lib headers for the mock library @Kaffeine do you think we might be able to use ofono-phonesim for testing instead?

[Kaffeine]

It would be much better to use ofono-phonesim, but I have no idea if it is actually doable.

It seems like I'm having some issues to get account manager to run? the ConnectionTest hangs in TelepathyHelper::instance() and If I make that test fail before that line I get the following warning in output:

tp-qt 0.9.7 WARN: Error parsing config file for connection manager "ofono" - introspecting

Telepathy spec says that connection manager should provide a config file with list of its protocols and capabilities (however clients must have a fallback mechanism that get the needed info by activating the connection manager and calling its methods).
TelepathyQt tests overcome this warning by modifying XDG_DATA_HOME environment variable: https://github.com/TelepathyIM/telepathy-qt/blob/master/tests/CMakeLists.txt#L6

I have some time and I'm going to try this branch right now :).

[Kaffeine]

Meh, telepathy-ofono already has CMake code for that.
If you run the tests via cmake --build . --target test or ctest -VV you'll see that it sets a lot of env vars.

FYI, I ported the tests to phonesim. You can see the code/commits here: https://gitlab.com/ubports/development/core/telepathy-ofono/-/merge_requests/45

If this repo is still active, let me know and I can update and submit a MR here as well. And if not, it might be good to set the repository read-only/archive?
