Hmm, looks like we can directly call
WebKit::Platform::current()->fileSystem()->resolveURL() without asking
FileSystemClient impl to do the task, as we no longer call any Source/web
specific code there after recent cleanup.  (As well as openFileSystem and
deleteFileSystem, they can be also removed from FileSystemClient.h interface)

Done. I'll make a separate patch for other functions.
