Builds a lookup-cache to speed up
g_dbus_interface_info_lookup_method(),
g_dbus_interface_info_lookup_signal() and
g_dbus_interface_info_lookup_property().
If this has already been called with info, the existing cache is
used and its use count is increased.
Note that info cannot be modified until
g_dbus_interface_info_cache_release() is called.
Since 2.30
