Moved Gdk test functions from Gtk+ to Gdk test utils.

* gdk/Makefile.am: added gdktestutils.h to public includes.

* gdk/gdk.h: added gdktestutils.h to public includes.

* gdk/gdk.symbols: added gdk_test_simulate_button, gdk_test_simulate_key,
gdk_test_render_sync.

* gdk/gdktestutils.h: new file, added prototypes for gdk_test_simulate_button,
gdk_test_simulate_key, gdk_test_render_sync.

* gdk/x11/Makefile.am: build gdktestutils-x11.c.

* gdk/x11/gdktestutils-x11.c: implemented gdk_test_simulate_button,
gdk_test_simulate_key, gdk_test_render_sync.

* gtk/gtktestutils.c:
* gtk/gtktestutils.h:
* gtk/gtk.symbols: removed gtk_test_simulate_button
gtk_test_simulate_key, gtk_test_xserver_render_sync.

* gtk/tests/testing.c: call gdk_test_render_sync.
