Clean up ill-advised or unusual header guards Leading underscores are ill-advised because such identifiers are reserved. Trailing underscores are merely ugly. Strip both. Our header guards commonly end in _H. Normalize the exceptions. Macros should be ALL_CAPS. Normalize the exception.

ui/dbus: add p2p=on/off option Add an option to use direct connections instead of via the bus. Clients are accepted with QMP add_client. This allows to provide the D-Bus display without a bus. It also simplifies the testing setup (some CI have issues to setup a D-Bus bus in a container).
