Telephony: Read IMSI using SIM I/O for CSIM/RUIM

Use Sim I/O command to read the EF_IMSIM to retrieve the IMSI
from the card, rather than using CommandsInterface.getIMSIForApp.
When both SIM and RUIM app exists, we cannot specify the
application for which we should retrieve the IMSI using the getIMSI
API, since SIM and RUIM have no AID.

Telephony: Delay SIM IO until SIM_READY

When SIM_REFRESH with SIM_INIT is received we need to
reread EFs but only if and when app is ready.

Do not update External state until we receive card status.

When updateExternalState is called before card state is received
from RIL, unwanted ABSENT state is getting broadcasted to
external apps incase of property apm_sim_not_pwdn is  set to 1.

So do not broadcast card state to external apps until we
receive card status from RIL atlease once.

SamsungQualcommRIL: fix handoff for good.

OperatorCheck: Add last known of good config when the array is null.
When the radio reset, it calls data connect. This fixes cases where
data is null because of this issue and causes apn to be null out.
