David Zeuthen 89a1b571ad GDBusMessage: Validate header fields when serializing/deserializing 
The D-Bus spec mentions exactly what header fields are required for
various message types. Add tests for this as well.

Also disallow empty interfaces for signals since the D-Bus spec says
this is Verboten already.
