The function WebCore::contentDispositionType() (defined in HTTPParsers.h) is unused. It was first added in the patch for bug #36395 and it was only used by the Chromium and Qt ports. Both the Chromium and Qt ports have long since been removed from the repository. We should remove WebCore::contentDispositionType().
