(VisibleCount): the number of parameters that will actually be

* generator/Method.cs (Initialize): set is_set based on
VisibleCount, not Count.

VisibleCount will be correct in Initialize.
* generator/MethodBody.cs (GetCallString, CallArrayLength,
Initialize): update to deal with accessors with multiple args.
* gtk/Clipboard.custom (SetText): implement as an Obsolete variant
of the Text property

* parser/gapi2xml.pl (addParamsElem): change the handling of
anonymous function pointer types in method signatures. Before, we
added a <callback> child to the <parameters> node, but the
generator just ignored it. Now we add the callback (with a made-up
name) to the toplevel node, and add an ordinary <param> node
referencing it to the <parameters> node. Also, if the last param
of the callback is a gpointer, rename it from "arg#" to "data" so
it will be treated correctly (as the user data passed from the
calling method). [Fixes #66241]
* art/art-api.raw:
* gdk/gdk-api-2.4.raw:
* gdk/gdk-api-2.6.raw: Regen
* generator/Parameters.cs (IsHidden): loosen the definition of
hideable user_data; it doesn't have to occur at the end of the
parameter list, as long as there's a callback arg before it.
* generator/MethodBody.cs (GetCallString): Use Parameters.IsHidden
to decide whether or not to squash user_data params, rather than
trying to duplicate its logic. As a side effect, this also causes
a handful of methods that take non-hidden IntPtr arguments to
start actually passing those arguments to C rather than always
passing IntPtr.Zero.
* generator/Method.cs (Equals, GetHashCode): Remove unnecessary
and possibly erroneous hashing overrides.
* gtk/Gtk.metadata: Hide Gtk.Container.ForeachFull, since it's
useless and wasn't in gtk# 1.0
* gtk/Menu.custom (Popup):
* gtk/TextIter.custom (ForwardFindChar, BackwardFindChar):
* gnome/App.custom (CreateMenusInterp, InsertMenusInterp,
CreateToolbarInterp):
* gnome/Client.custom (RequestInteractionInterp):
* gnome/Popup.custom (MenuDoPopupModal, MenuDoPopup): Add
[Obsolete] compat overloads for methods that have now lost a
useless IntPtr.
