Comment 4 for bug 1613469

Especially since the rest of our stack apparently uses libqofono... See bug 1612702 that wants it in main for indicator-network, address-book-app and ubuntu-system-settings.

Why did we choose onofo-qt for telepathy-ofono? How much work would it be to switch to libqofono and standardize, so we don't have duplicate libraries in main?
