InCall UI changes for incoming Telecomm calls.

1. Send commands back to Telecomm when user hits answer/reject
2. Appropriately map Telecomm call states to in-call call states for
   call updates sent from Telecomm.
3. Use the working version of CallList.onUpdate(). The one we were using
   previously wasn't running in old code and didn't do everything
   necessary for supporting the incoming call screen. Added a TODO to
   remove it completely later.
