Source/WebCore: 

This patch updates Geolocation to use some more modern WebCore
mechanisms.  Previously, Geolocation used a Frame as a context object,
which required a bunch of manual integration with the PageCache as well
as custom signaling for Geolocation::reset().  After this patch,
Geolocation subclasses ActiveDOMObject, which does all this work
automatically.

Rather than indirecting through the Frame to get the SecurityOrigin, we
should get the SecurityOrigin directly from ScriptExecutionContext.

    - We no longer special-case Geolocation.
