Add method to retrieve MSISDN for CDMA/LTE devices.

For CDMA/LTE devices, the MDN and MSISDN may be different.
Add a new method getMsisdn() to the Phone interface to return the
MSISDN. For GSM/UMTS, this will be the same as getLine1Number().
For CDMA/LTE, getLine1Number() will continue to return the MDN
and getMsisdn() will return the MSISDN.
