Implement icon theme caching. (#154034, Martijn Vernooij, caching schema

	Implement icon theme caching.  (#154034, Martijn Vernooij,
	caching schema proposed by Owen Taylor, initial implementation
	by Anders Carlsson)

	* gtk/gtkdebug.h:
	* gtk/gtkmain.c: Add a "icontheme" debug flag.

	* gtk/Makefile.am (gtk_c_sources): Add gtkiconcache.c
	(gtk_private_h_sources): Add gtkiconcache.h
	(bin_PROGRAMS): Add gtk-update-icon-cache

	* gtk/gtkicontheme.c: Use icon caches if they are available.
	Currently, GTK+ uses the cache to get information about the
	available sizes, image file formats and .icon files. The
	actual image data, and the .icon file contents are not
	cached yet.

	* gtk/updateiconcache.c: A cmdline utility for generating
	icon cache files.

	* gtk/gtkiconcache.h:
	* gtk/gtkiconcache.c: The glue code to mmap an icon cache
	file and manage the information it contains.
