new CallForwarding()
The module initializes the call forwarding icon states and update the icons when call forwarding states changed.
The module initializes the call forwarding icon states and update the icons when call forwarding states changed. As we are not able to query the current call forwarding states from the carrier on startup, we initialized the icon state based on the cached information. When call forwarding states are changed, the module caches the state along with the corresponding iccId.

Methods
_addEventHandlers()
Add related event handlers.
Add related event handlers. The sim cards may not be ready when starting. We register to "simslot-cardstatechange" and "simslot-iccinfochange" for updating the icons when ready. When users query the current call forwarding states in settings app, 'ril.cf.carrier.enabled' is used to notify the state changes. When users change the call forwarding states in settings app, we will receive the 'cfstatechange' event. All the events must be watched to have correct icon states.
