SubscriptionController: do not return info for invalid slot id

This causes Keyguard to crash when you switch a dual SIM phone into
single SIM mode for testing because the old data with the now-invalid
slotId is stored in the database.

    Fix crash of Samsung phones

    Using an alternative SMS app like chompSMS leads to a crash as
    sendResult is an array without any entries (sendResult[0] is accessed)
    The default SMS app does not show this because mCurrntCmd == null

    Samsung STK: Fix SMS-based STK

    SEND_SMS was falling through to SEND_USSD (which used to do nothing
    until USSD support was added) causing an Exception because cmdParams
    is not an instance of SendUSSDParams.

    Fix by using type-checking instead of checking if Samsung STK is
    enabled (because SendSMSParams and SendUSSDParams will only be
    created if Samsung STK is enabled.)

DCTracker: HACK Fix eHRPD/LTE data connection.

* UICC controller is suppose to send a event that says uicc updated
  We are experiencing a race condition when UICC is init before the
  radio start which cause the sim is not ready response from radio.
* This forces data when we have cdma voice connection.

Telephony: DcTracker: Fix CDMA APN Data issues.

Fix CDMA data issue when it can't find an APN match. This fixes cases
CDMA NV or RIUM/SIM doesn't have the information to pass on.
It assumes GSM like mode on CDMA. So fix that and pass on to CDMA
stubbed apn found in android 4.2.
