Emit D-Bus "org.freedesktop.DBus.Properties.PropertiesChanged" signal.

This deprecates the "se.recompile.Mandos.Client.PropertyChanged"
signal.  The new signal also adds support for noticing changes to the
"se.recompile.Mandos.Client.Secret" write-only property.

* mandos (dbus_annotations): Fix usage example in doc string.
  (DBusObjectWithProperties.PropertiesChanged): New; from D-Bus
                                                standard.
  (ClientDBus._interface): Set early instead of later.
  (ClientDBus.notifychangeproperty): Take new "invalidate_only"
                                     parameter, and pass in _interface
                                     as a default keyword argument.
  (ClientDBus.notifychangeproperty/setter): Also emit
                                            PropertiesChanged signal;
                                            emit new value or
                                            invalidation depending on
                                            "invalidate_only".
  (ClientDBus.secret): Apply notifychangeproperty with
                       "invalidate_only=True".
  (ClientDBus._foo): Removed defunct interface annotation.
  (ClientDBus.PropertyChanged): Add annotation; this method is now
                                deprecated.
  (main/MandosDBusService.GetAllClientsWithProperties): Use dictionary
                                                        comprehension.
* DBUS-API (Mandos Client Interface/Signals/PropertyChanged): Removed.
* mandos-monitor: Use standard "PropertiesChanged" signal instead of
                  old signal "PropertyChanged".
  (MandosClientPropertyCache.__init__): Connect to signal
                                        PropertiesChanged instead of
                                        PropertyChanged.
  (MandosClientPropertyCache._property_changed): Removed.
  (MandosClientPropertyCache.property_changed): Renamed to
                                                "properties_changed"
                                                and adapted to new
                                                call signature.
  (MandosClientWidget.properties_changed): - '' -

      The computers run a small client program in the initial RAM disk
69
62
      environment which will communicate with a server over a network.
70
63
      All network communication is encrypted using TLS.  The clients
71
 
      are identified by the server using a TLS public key; each client
 
64
      are identified by the server using an OpenPGP key; each client
72
65
      has one unique to it.  The server sends the clients an encrypted
73
66
      password.  The encrypted password is decrypted by the clients
74
 
      using a separate OpenPGP key, and the password is then used to
 
67
      using the same OpenPGP key, and the password is then used to

      unlock the root file system, whereupon the computers can
76

      continue booting normally.
