Fix bug 3345948 - ActionBar.show()/hide() shouldn't animate if called
before first layout

Enable/disable the action bar show/hide animation as part of the
activity/dialog lifecycle. This allows apps to set action bar
visibility state as the activity first becomes visible or returns to
visibility without the associated animation.
