Add search file support in the GtkFileChooser. Original patch by Federico

2007-05-02  Emmanuele Bassi  <ebassi@gnome.org>

	Add search file support in the GtkFileChooser. Original patch
	by Federico Mena Quintero; patch updated by Matthias Clasen.
	See bug #344785.

	* gtk/gtksearchengine.[ch]: Private search engine abstraction
	object.

	* gtk/gtksearchenginebeagle.[ch]: Private search engine
	implementation using libbeagle (via g_module_open()).

	* gtk/gtksearchenginesimple.[ch]: Private search engine
	implementation using file tree walking.

	* gtk/gtksearchenginetracker.[ch]: Private earch engine
	implementation using libtracker (via g_module_open()).

	* gtk/gtkquery.[ch]: Private query object for the search
	engines.

	* gtk/gtkfilechooserprivate.h:
	* gtk/gtkfilechooserdefault.c: Use the GtkSearchEngine to
	query a search engine backend using GtkQuery; create a new
	operating mode, OPERATION_MODE_SEARCH, and call the common
	operating mode OPERATION_MODE_BROWSE; add support for virtual
	shortcuts inside the shortcuts model and create a new "Search"
	virtual shortcut.

	* gtk/Makefile.am: Update the build with the new files
