[PATCH 0/2] CPIN polling mechanism

As no SIM card status urc is available with ZTE and Speedup, the SIM state is set by default to OFONO_SIM_STATE_INSERTED even if no SIM card is inserted. Also, we are facing with a modem latency after the ttyUSB is opened (first AT commands are failing and the PIN status query returns CME ERROR: 14 - SIM Busy). So, to deal with those 2 issues, this patch set is introducing a preliminary PIN status polling in the ZTE/Speedup plugins. In practice, this polling is started after the modem is enabled and stopped when the CPIN query returns an other result than CME ERROR 14 or when the polling duration exceeds 5 seconds. As a result, the SIM state is set according the result of the CPIN query and the update of the modem_powered state is postponed which delays the next AT commands. Developed conjointly with philippe nunes.
