[RFC sim-ready-v0 PATCH 0/3] ofono_sim_ready_notify

Hi all, Here is my stab at the ofono_sim_ready_notify(). If SIM is not ready, the ofono_sim_driver indicates that with query_passwd_state callback returning OFONO_SIM_PASSWORD_INVALID. After the driver determines that the SIM is ready, it calls ofono_sim_ready_notify(). The patches has been tested with the mbm and the new isimodem sim driver by Jukka Saunamaki. The isimodem driver demonstrates also the case where PIN is disabled and SIM gets eventually ready. --Pekka
