 Calls via 4G using VoLTE are not supported (*except CSFB, which redirects to 2G/3G)

 - Document the relevant ABIs and add support to libqmi
 - Implement a IMS configuration daemon (OpenIMSd) which will communicate with

 Our implementation will heavily use the baseband in the same way as Android is use the baseband to allow VoLTE. By using the baseband, it should be possible to allow handover between 2G/3G and VoLTE while in a call.
