        - fix <rdar://problem/5715692> REGRESSION (r28570): JavaScript window.scrollTo()
          calls no longer accept 'undefined' values

        By default, we should accept non-numeric parameters and non-integral numbers for
        parameters that expect integers, without throwing exceptions.

        While creating the test for this, I ran into a couple minor bugs with the
        functions involved, and this patch fixes those too.

        Test: fast/dom/non-numeric-values-numeric-parameters.html

        * bindings/js/JSHTMLOptionsCollectionCustom.cpp:
        (WebCore::JSHTMLOptionsCollection::add): Added. This function has unusual behavior
        when passed non-integral values for its second parameter, so it needs to be written
        by hand. I think that [Custom] is better here than inventing a new keyword.

        * bindings/scripts/CodeGeneratorJS.pm: Changed default for "long" and "unsigned long"
        to ignore errors rather than failing due to type differences. Also changed a couple
        functions to use hashes.

        * css/CSSStyleSheet.h:
        (WebCore::CSSStyleSheet::removeRule): Remove overload of removeRule without a second
        parameters. While we do allow this from JavaScript, it's not a true optional parameter,
        but rather just a case of "you can omit parameters and they are treated as undefined"
        combined with "undefined turns into 0 when passed to a function that takes an integer".
        * css/CSSStyleSheet.idl: Removed [Optional] on the index parameter for removeRule.
        This is not truly an optional parameter.

        * dom/ProgressEvent.cpp:
        (WebCore::ProgressEvent::initProgressEvent): Updated this function to match other
        DOM event init functions -- important to do nothing if this is called on the an
        already-dispatched event and we need to respect the bubble and cancelable arguments.
        Also removed initProgressEventNS. We don't support namespaced events, and if we add
        support, it should be across all event classes, not just ProgressEvent.
        * dom/ProgressEvent.h: Removed initProgressEventNS.
        * dom/ProgressEvent.idl: Ditto.

        * dom/Range.cpp:
        (WebCore::Range::createContextualFragment): Added a check for 0. This can happen
        if the passed-in start container is a node that's not an HTML element and also
        does not have a parent.

        * html/HTMLOptionsCollection.idl: Added the [Custom] attribute to add, since the
        rules for processing its parameters are unusual.

        * page/DOMSelection.cpp: Removed the version of setPosition that has only
        one parameter. The offset is not really optional.
        * page/DOMSelection.h: Ditto.
        * page/DOMSelection.idl: Removed the [Optional] keyword for the second parameter of
        setPosition. It's not a true optional parameter (see discussion of removeRule above).

        * page/DOMWindow.cpp:
        (WebCore::DOMWindow::adjustWindowRect): Simplified logic for constraining the X
        and Y coordinates, in a way that makes them work even when the window coordinates
        are infinite. Also strengthened the assertion.

        * Scripts/make-js-test-wrappers: Look at the whole LayoutTests tree, not just the fast
        and svg subdirectories. Added some more exceptions for the benefit of the fast/dom
        subdirectory.

        There's no reason for us to be strict about this -- we generally treat missing parameters the
        same as if "undefined" had been passed with few exceptions.
