Rename nsGeolocation to Geolocation. Split nsGeoPostion to GeolocationPosition and GeolocationCoordinates. Fix some include guards and comments referencing outdated interfaces. Differential Revision: https://phabricator.services.mozilla.com/D52515 --HG-- rename : dom/geolocation/nsGeolocation.cpp => dom/geolocation/Geolocation.cpp rename : dom/geolocation/nsGeolocation.h => dom/geolocation/Geolocation.h rename : dom/geolocation/nsGeoPosition.cpp => dom/geolocation/GeolocationPosition.cpp rename : dom/geolocation/nsGeoPosition.h => dom/geolocation/GeolocationPosition.h extra : moz-landing-system : lando
