* generator/ManagedCallString.cs: revert last change. There are a
lot of "broken" callback sigs out there which expose user data because
it's not in the last parameter in the list. I don't think we can
reasonably make a change to hide all those at this point. This change
at least hides all the user_data which comes right before a GError
param at the end of the list. I need to follow up with a change which
handles data parameters in any parameter position, but allows the user
to mark "exposed" data params for compatibility reasons.
* generator/Parameters.cs: hide data params which are at the end of a
list behind an error param.
* gtk/Gtk.metadata: mark an array parameter on
TextBufferDeserializeFunc.
