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 and returns the
   number of attempts remaing in case of failure.
-> FDN Service state was derived based on the state of PIN2. Update the
   state of FDN service based on the FACILTY_LOCK messages instead.
-> Change the default value of function getIccLockEnabled to false.
   When sim is deactivated/absent & user navigates to
   Settings->Security->Set up SIM/RUIM card lock,
   checkbox for "Lock Sim Card" option should be
   unchecked by default.
-> PIN1 can be changed only after enabling SIM lock. RIL returns
   REQUEST_NOT_SUPPORTED error if user tries to change PIN1 without
   enabling SIM lock.
   Handle the error and display appropriate message when trying to
   change PIN1 using MMI code.
-> Added MMI support for change PIN1/PIN2 and unblocking PIN2
