Allow %NULL for style to mean "revert to default style"

Allow %NULL for style to mean "revert to default style"

	* gtk/gtkwidget.c (gtk_widget_set_style): Allow %NULL
	for style to mean "revert to default style"

	* gtk/gtkwidget.[ch] (gtk_widget_set_rc_style,
	  gtk_widget_restore_default_style): Make this functions
	deprecated aliases for gtk_widget_set_style (widget, NULL).

	* gtk/gtkwidget.[ch]: Remove:
	   gtk_widget_set_default_style ()
	   gtk_widget_push_style ()
	   gtk_widget_pop_style ()
	These functions interact are overriden by RC files, and
	thus virtually useless, and complicated.

        * gtk/gtkrc.c: Add a GtkRcContext structure to hold
	most of the previous global variables in gtkrc.c. This is
	in preparation for multi-head, since each screen can
	have different GtkSettings and RC information.

	* gtk/gtkrc.[ch]:

	* gtk/gtkrc.h (struct _GtkRcStyleClass): Add a
	GtkSettings parameter to GtkRcStyle::parse.

	* gdk/x11/gdkevents-x11.c gtk/gtksettings.c gtk/gtkrc.c:
	Add two new settings gtk-theme-name, gtk-key-theme-name,
	for RC files that are loaded by name after reading
	the default RC files.

	* gtk/gtkrc.c: Allow priorities for styles, as wll as
	bindings.

	* gtk/gtkenums.h gtk/gtkrc.c: Add GTK_PATH_PRIO_THEME,
	and use it by default for RC files loaded via
	gtk-theme-name, gtk-key-theme-name.

	* gtk/gtkiconfactory.c (gtk_icon_source_set_filename)
        gtk/gtkrc.c (gtk_rc_parse_pixmap_path_string)
	tests/testgtkrc: Require pathnames to be absolute.

	* gtk/gtkrc.c gtk/gtkiconfactory.c: Look up the full filename for
	the source when parsing, since the operation of looking up a
	pixmap from an RC file depends on the parsing context.

	* gtk/gtkrc.c (gtk_rc_context_reparse_all): Automatically
	reset RC styles on all widgets when files are reparsed.

	* tests/testgtk.c (create_rc_file)
	  gtk/gtkwindow.c (gtk_window_read_rcfiles):
	Simplify, now that gtk_rc_reparse_all() resets styles on
	all widgets itself.

	* gtk/gtkmain.c (gtk_get_default_language): Fix broken
	return value.

	* gtk/gtksettings.[ch] (gtk_settings_install_property[_ch]): Remove
	GtkSettings argument.

	* gtk/gtksettings.[ch] (gtk_settings_get_default): Rename from
	gtk_settings_get_global().

	* gtk/gtkwidget.[ch]: Add a function gtk_widget_Get_settings()
	to get the appropriate GtkSettings for a widget. (For now,
	just gets the default GtkSetttings.)

	* gtk/gtkcolorsel.c gtk/gtkentry.c gtk/gtkmenu.c gtk/gtkmenubar.c
	  gtk/gtktextview.c gtk/gtktoolbar.c: Fixes for GtkSettings
        changes.

	* gtk/gtkrc.[ch]: Add gtk_rc_get_style_by_paths() to allow
	getting a style for a path without actually having a widget.
	(Allows using a style for a subpart of a widget, for
	example.)

	* gtk/gtkrc.[ch]: Add gtk_rc_reparse_all_for_setting() to allow forcing
	the RC files to be reloaded for just one GtkSettings
	(not sure how useful this really is.)

	* gtk/gtkrc.h: Deprecate
	gtk_rc_add_widget_name/widget_class/class_style
