Synchronously connects and sets up a D-Bus client connection for exchanging D-Bus messages with an endpoint specified by @address which must be in the D-Bus address format.
This constructor can only be used to initiate client-side connections - use g_dbus_connection_new_sync() if you need to act as the server. In particular, @flags cannot contain the %G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_SERVER or %G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_ALLOW_ANONYMOUS flags.
This is a synchronous failable constructor. See g_dbus_connection_new_for_address() for the asynchronous version.
If @observer is not %NULL it may be used to control the authentication process.
