Fix a bunch of lifecycle and memory management problems in the mono bindings. * mono/Arguments.cs (Arguments): Implement IDisposable * mono/Bus.cs (Bus): Don't allow public instantiation. This is strictly a static class. * mono/Connection.cs: Move the DBusObjectPathVTable and associated delegates into this file. (Connection): Implement IDisposable. (Dispose): Disconnect the connection and set the raw connection pointer to IntPtr.Zero. (~Connection): Call Dispose(). (RegisterObjectPath): Added. Manages the registration of object paths so we can cleanly disconnect them at dispose/finalize time. (UnregisterObjectPath): Ditto. (set_RawConnection): Unregister all of the object paths when changing the underlying DBusConnection. Add them back onto the new connection, if any. * mono/Handler.cs: Don't implement IDisposable; it doesn't use any more unmanaged resources anymore, so it's not necessary. Move all the DBusObjectPathVTable stuff out of here. (Handler): Save references to our delegates so that they don't get finalized. Call Connection.RegisterObjectPath() instead of dbus_connection_register_object_path() directly. (Message_Called): Dispose the message after we're finished with it. * mono/Message.cs (Message): Implement IDisposable. (Dispose): Dispose the Arguments, and set the RawMessage to IntPtr.Zero. (SendWithReplyAndBlock): We own the ref to the reply that comes back from dbus_connection_send_with_reply_and_block() so add a comment about that and unref it after we've constructed a managed MethodReturn class around it. Fixes a big, big leak. * mono/ProxyBuilder.cs: Reflect into Message to get the Dispose method. (BuildSignalHandler): After we've sent the Signal message, dispose of it. (BuildMethod): Dispose of the method call and reply messages after we've sent the message and extracted the data we want from the reply. * mono/Service.cs (UnregisterObject): Don't call handler.Dispose() anymore. (Service_FilterCalled): Dispose of the message after we're finished with it.
