The functions implemented in ResourceHandle[Curl|Soup].cpp and SynchronousLoaderClient[Curl|Soup].cpp are not used in WebKit2, so they are empty implementations and will not be added in the future. So we would like to move these empty functions to ResourceHandle.cpp and SynchronousLoaderClient.cpp for better maintainability in the future. Also remove unnecessary includes.
