The timeout timer of a geolocation request holds a strong reference to
the request. This can cause the window to leak if the request is not
completed before the tab containing the window is closed.
To fix this, I made the timer instead hold a strong reference to a
wrapper class that has only a weak reference to the request. The
request destructor must now cancel the timeout timer.
I also outlined a call to StopTimeoutTimer() in
nsGeolocationRequest::Shutdown().
