* Since phone process can be restarted, this class provides a centralized place

*
* Change-Id: I450c968bda93767554b5188ee63e10c9f43c5aa4 fixes bugs 16148026
* and 15973975 by saving the phoneId of the registrant and then using the
* phoneId when deciding to to make a callback. This is necessary because
* a subId changes from to a dummy value when a SIM is removed and thus won't
* compare properly. Because getPhoneIdFromSubId(int subId) handles
* the dummy value conversion we properly do the callbacks.
*
* Eventually we may want to remove the notion of dummy value but for now this
* looks like the best approach.
