Source/WebCore:

The prerender case isn't quite a resource load, and using resource loading to
retrieve them has constrained the API, and unnecessarily complicated the loader.

The new Prerenderer and PrerenderHandle let <link rel=prerender...> elements signal
removal and unload to their platform.

No new tests, as this interface requires a full platform to work, and doesn't affect layout.  Test
it with your platform when implemented for it.

LayoutTests:

The prerender case isn't quite a resource load, and using resource loading to
retrieve them has constrained the API, and unnecessarily complicated the loader.

The new Prerenderer and PrerenderHandle let <link rel=prerender...> elements signal
removal and unload to their platform.

These tests are being removed, and expectations updated, because the old phantom-load
prerendering interface was susceptible to layout testing, and the new interface requires
a full platform to test, so it can't really be a layout test.
