Auto-dive into trees that contain only a single subtree

When walking into a tree in PathServlet, keep track of which path
components only contained a single subtree entry, and pass this
information along to GitilesView.getBreadcrumbs(). This creates URLs
with a special sentinel ?stay to disable auto-diving.
