Steps in handling emergency calls:
- subscribe to modem online notifications
- emergency call detected (phone number is an emergency number)
- increment emergency mode 
  - advertise "Emergency" property change on D-Bus (first call)
  - set modem online (minimal setup) if mode was offline
    - adevertise "Online" property change on D-Bus
- if modem is not online postpone making the call, otherwise make
  the emergency call
- when modem online notification comes and there is postponed emergency call
  request, make the emergency call
- when an emergency call ends decrement emergency mode
  - set modem to pre emergency call state (last call)
    - advertise "Online" property change on D-Bus (if any)
  - advertise "Emergency" property change on D-Bus (last call)
