Zbigniew Jędrzejewski-Szmek ec6bda56cb bus-message: avoid an infinite loop on empty structures ...

The alternative would be to treat gvariant and !gvariant messages differently.
But this is a problem because we check signatures is variuos places before we
have an actual message, for example in sd_bus_add_object_vtable(). It seems
better to treat things consistent (i.e. follow the lowest common denominator)
and disallow empty structures everywhere.
