* Signal signedness and naming corrections, plus GtkType fixes:
* gtk/gtkadjustment.c:
* gtk/gtkbutton.c:
* gtk/gtkcheckmenuitem.c:
* gtk/gtkclist.c:
* gtk/gtkcolorsel.c:
* gtk/gtkcontainer.c:
* gtk/gtkcurve.c:
* gtk/gtkdata.c:
* gtk/gtkeditable.c:
* gtk/gtkentry.c:
* gtk/gtkhandlebox.c:
* gtk/gtkinputdialog.c:
* gtk/gtkitem.c:
* gtk/gtklist.c:
* gtk/gtkmenuitem.c:
* gtk/gtkmenushell.c:
* gtk/gtknotebook.c:
* gtk/gtkstatusbar.c:
* gtk/gtktoolbar.c:
* gtk/gtktree.c:
* gtk/gtktreeitem.c:
* gtk/gtkwidget.c:
* gtk/gtktogglebutton.c:
* gtk/gtkwindow.c:
made the <widget>_signals[] arrays of type guint rather than gint.
* gtk/gtkwidget.c (gtk_widget_get_ancestor): made widget_type a GtkType.
* gtk/gtkcombo.h:
handler ids need to be of type guint (entry_change_id, list_change_id).
* gtk/gtkaccelerator.c:
changed signal_num to signal_id and typed it guint.
* gtk/gtkmain.c: made gtk_ndebug_keys a guint.
* gtk/gtkmenu.h:
* gtk/gtkmenu.c:
(gtk_menu_popup): made button a guint.
(gtk_menu_set_active): made index a guint.
* gtk/gtkmenuitem.h:
* gtk/gtkmenuitem.c:
made accelerator_signal a guint.
* gtk/gtkoptionmenu.h:
* gtk/gtkoptionmenu.c:
(gtk_option_menu_set_history): made index a guint.
* gtk/gtksignal.h:
* gtk/gtksignal.c:
* gtk/gtkobject.h:
* gtk/gtkobject.c: changed a bunch of prototypes to take guints rather
than gints. also made some conversions from guint to GtkType, left over
from when the fundamental-types system was introduced.
* gtk/gtkobject.h:
* gtk/gtkobject.c: made object_data_id_index and obj_count guints.
made *signals and nsignals guints in GtkObjectClass.
