        More scaffolding for redirect tracking. No behavior change yet.

        * bindings/js/JSHTMLFormElementCustom.cpp:
        (WebCore::JSHTMLFormElement::submit): Added scaffolding necessary for
        redirect checking in a form submission through JS. (Currently, we
        just specify "no redirect.")

        * bindings/js/ScriptController.h:
        * bindings/js/ScriptController.cpp:
        (WebCore::ScriptController::processingUserGesture):
        (WebCore::ScriptController::processingUserGestureEvent):
        (WebCore::ScriptController::isJavaScriptAnchorNavigation): Refactored
        user gesture check to make it more clear.

        (WebCore::ScriptController::pageIsProcessingUserGesture): Added a helper
        for checking if there's a user gesture in any frame on the page (a more
        relaxed rule than our popup blocking rule, which requires the user
        gesture to occur in the frame that's executing JavaScript.)

        * html/HTMLFormElement.h:
        * html/HTMLFormElement.cpp:
        (WebCore::HTMLFormElement::submit): Added scaffolding necessary for
        redirect checking in a form submission through the DOM. (Currently, we
        just specify "no redirect.")

        * html/HTMLFormElement.idl: Made submit custom so it can participate
        in redirect checking.

        * loader/FrameLoader.h:
        * loader/FrameLoader.cpp:
        (WebCore::FormSubmission::FormSubmission): Clarified some names, and
        added a "lockHistory" parameter to form submissions, to match other
        navigations.

        (WebCore::FrameLoader::submitFormAgain):
        (WebCore::FrameLoader::submitForm): Use the lockHistory parameter.

        (WebCore::FrameLoader::userGestureHint): Refactored this function for
        clarity, and added a FIXME for a change I was too scared to make myself.
        (Really, we should just get rid of this function.)

        (WebCore::FrameLoader::loadFrameRequestWithFormAndValues): Refactored
        to pass a FrameLoadType to form posts, too, so they can participate in
        redirect tracking.

        (WebCore::FrameLoader::loadPostRequest):
        (WebCore::FrameLoader::continueFragmentScrollAfterNavigationPolicy):
        (WebCore::FrameLoader::loadItem): Use the lockHistory parameter.

        More redirect layout test work.
        
        Added tests (expected to fail) for form submission via JavaScript:
        
        * http/tests/history/redirect-js-form-submit-0-seconds-expected.txt: Added.
        * http/tests/history/redirect-js-form-submit-0-seconds.html: Added.
        * http/tests/history/redirect-js-form-submit-2-seconds-expected.txt: Added.
        * http/tests/history/redirect-js-form-submit-2-seconds.html: Added.
        * http/tests/history/redirect-js-form-submit-before-load-expected.txt: Added.
        * http/tests/history/redirect-js-form-submit-before-load.html: Added.
        
        Updated these tests to dump their back/forward lists, to check for
        back/forward regressions, and to use # instead of ? to communicate between
        URLs, since, to my surprise, form submissions can't use query strings.
