Log Message

Don't send geolocation permission requests when the page is not visible
<rdar://problem/17208715>
https://bugs.webkit.org/show_bug.cgi?id=134989

Reviewed by Darin Adler.

Instead of eagerly requesting geolocation permission for pages that aren't visible,
store a set of pending requests, and send them only once the page has become visible.

* Modules/geolocation/GeolocationController.cpp:
(WebCore::GeolocationController::GeolocationController):
(WebCore::GeolocationController::~GeolocationController):
(WebCore::GeolocationController::requestPermission):
(WebCore::GeolocationController::cancelPermissionRequest):
(WebCore::GeolocationController::viewStateDidChange):
(WebCore::provideGeolocationTo):
* Modules/geolocation/GeolocationController.h:
Store pending requests to be fired once the page is visible.

* WebCore.xcodeproj/project.pbxproj:
Add ViewStateChangeObserver.h

* page/Page.cpp:
(WebCore::Page::addViewStateChangeObserver):
(WebCore::Page::removeViewStateChangeObserver):
(WebCore::Page::setViewState):
* page/Page.h:
Add a set of registered view state observers, and notify them when the
view state changes.

* page/ViewStateChangeObserver.h: Added.
(WebCore::ViewStateChangeObserver::~ViewStateChangeObserver):
Add an observer that can register with the page for view state changes.
