[RFC sim-authenticate PATCH 0/3]

Hi all, Here is first proposal for SIM authentication API. The API provides access to ordinary SIM authentication methods. The first two methods are intended for implementing EAP authentication using cellular authentication mechanisms, the third one for implementing AKA authentication algorithm used with IMS. There can be special EAP application implementing EAP protocol and using secrets and authentication methods separate from cellular authentication on SIM card; it is not handled here. I have no clear idea how the GBA authentication should be used, I'll add that later. --Pekka
