A set of tests to exercise chrome menus as well as parts of bookmark

bar view. These are disabled until we straighten out the buildbot that
is always logged in.

BUG=1318922
TEST=this is just a bunch of tests.

+// Base class for Views based tests that dispatch events.
+//
+// As views based event test involves waiting for events to be processed,
+// writing a views based test is slightly different than that of writing
+// other unit tests. In particular when the test fails or is done you need
+// to stop the message loop. This can be done by way of invoking the Done
+// method.
+//
+// Any delayed callbacks should be done by way of CreateEventTask.
+// CreateEventTask checks to see if ASSERT_XXX has been invoked after invoking
+// the task. If there was a failure Done is invoked and the test stops.
+//
+// ViewEventTestBase creates a Window with the View returned from
+// CreateContentsView. The preferred size for the view can be customized by
+// overriding GetPreferredSize. If you do not override GetPreferredSize the
+// preferred size of the view returned from CreateContentsView is used.
+//
+// Subclasses of ViewEventTestBase must implement two methods:
+// . DoTestOnMessageLoop: invoked when the message loop is running. Run your
+//   test here, invoke Done when done.
+// . CreateContentsView: returns the view to place in the window.
+//
+// Once you have created a ViewEventTestBase use the macro VIEW_TEST to define
+// the fixture.
+//
+// I encountered weird timing problems in initiating dragging and drop that
+// necessitated ugly hacks. In particular when the hook installed by
+// ui_controls received the mouse event and posted a task that task was not
+// processed. To work around this use the following pattern when initiating
+// dnd:
+//   // Schedule the mouse move at a location slightly different from where
+//   // you really want to move to.
+//   ui_controls::SendMouseMoveNotifyWhenDone(loc.x + 10, loc.y,
+//       NewRunnableMethod(this, YYY));
+//   // Then use this to schedule another mouse move.
+//   ScheduleMouseMoveInBackground(loc.x, loc.y);
