/**
 * #GDBusProxy is a base class used for proxies to access a D-Bus
 * interface on a remote object. A #GDBusProxy can be constructed for
 * both well-known and unique names.
 * 
 * By default, #GDBusProxy will cache all properties (and listen to
 * changes) of the remote object, and proxy all signals that gets
 * emitted. This behaviour can be changed by passing suitable
 * #GDBusProxyFlags when the proxy is created. If the proxy is for a
 * well-known name, the property cache is flushed when the name owner
 * vanishes and reloaded when a name owner appears.
 * 
 * If a #GDBusProxy is used for a well-known name, the owner of the
 * name is tracked and can be read from
 * #GDBusProxy:g-name-owner. Connect to the #GObject::notify signal to
 * get notified of changes. Additionally, only signals and property
 * changes emitted from the current name owner are considered and
 * calls are always sent to the current name owner. This avoids a
 * number of race conditions when the name is lost by one owner and
 * claimed by another. However, if no name owner currently exists,
 * then calls will be sent to the well-known name which may result in
 * the message bus launching an owner (unless
 * %G_DBUS_PROXY_FLAGS_DO_NOT_AUTO_START is set).
 * 
 * The generic #GDBusProxy::g-properties-changed and
 * #GDBusProxy::g-signal signals are not very convenient to work with.
 * Therefore, the recommended way of working with proxies is to subclass
 * #GDBusProxy, and have more natural properties and signals in your derived
 * class. This [example][gdbus-example-gdbus-codegen] shows how this can
 * easily be done using the [gdbus-codegen][gdbus-codegen] tool.
 * 
 * A #GDBusProxy instance can be used from multiple threads but note
 * that all signals (e.g. #GDBusProxy::g-signal, #GDBusProxy::g-properties-changed
 * and #GObject::notify) are emitted in the
 * [thread-default main context][g-main-context-push-thread-default]
 * of the thread where the instance was constructed.
 * 
 * An example using a proxy for a well-known name can be found in
 * [gdbus-example-watch-proxy.c](https://git.gnome.org/browse/glib/tree/gio/tests/gdbus-example-watch-proxy.c)
 *
