SMS over IMS bug fixes

This change includes the following:
1) SMS over IMS remaining patches which address review comments

2) Fix for Bug:11378993
For MT SMS over IMS, if an application uses the createFromPdu(byte[] pdu) API
instead of createFromPdu(byte[] pdu,String format) API, we first try to create
SmsMessage from raw PDU with the format of active phone. That either returns a
valid SmsMessage object or throws a RuntimeException causing the correct format
to be used the next time. If GsmSmsAddress is not valid, we should throw
a RuntimeException which is handled by createFromPdu(byte[] pdu)

3) Fix for Bug:11424054
Register for ICC changes and handle new SMS on ICC
