Telephony: Few PIN/PUK fixes

Following changes have been made as part of this:
-> Changes done to display retry counter on wrong entry of
   PIN1,and message to indicate Code accepted/PIN1 blocked
   during PIN1 verification as per certain carrier requirements.
->The current APIs that are used to verify the PIN and PUK only convey
  whether the operation succeeded or failed. As a result on ANY failure
  clients ask the user to re-enter the PIN.
  Add 2 new APIs that report the actual error code in case of failure.
->Display the complete text including attempts remaining to
 unlock PIN on SimUnlockScreen if user entered incorrect PIN.
 On some devices the display text is ellipsized when trying to
 display on a single line.
