Store the request data into a temporary struct
Store the request data into a temporary struct

Instead of using the deprecated requestor-serial property and
requestor-client-id (which we might deprecate too), store these data into a
structure embedded to the channel with g_object_set_data().

Once the channel is dispatched we don't need it anymore, so free it.
