dbus: Emit more information over D-Bus

Browse source 
Allows informing the connection manager of additional information on CQM
events. Allows the connection manager to request the same information
on demand by using the existing "SignalPoll" method.

* Add new property "SignalChange"
        * Add storage for wpa_signal_info into wpa_supplicant context
          object
        * Copy memory from event to context object on CQM Event
* Write a common conversion method to be used by both "SignalPoll" and
  this property
