        <rdar://problem/6093281> - autocomplete="off" should work when going back

        Taken care of in two ways:
        1 - Listening for the page cache notification to clear the form, in cases where the page
            is being restored from the page cache
        2 - Not saving such form elements when doing the normal "save state" to a history item,
            for cases with no page cache

        * html/HTMLFormElement.cpp:
        (WebCore::HTMLFormElement::~HTMLFormElement):
        (WebCore::HTMLFormElement::parseMappedAttribute):
        (WebCore::HTMLFormElement::didRestoreFromCache):

        (WebCore::HTMLInputElement::parseMappedAttribute):
        (WebCore::HTMLInputElement::needsCacheCallback):
        (WebCore::HTMLInputElement::registerForCacheCallbackIfNeeded): Only register if the type or attribute
          indicate we should.
        (WebCore::HTMLInputElement::unregisterForCacheCallbackIfNeeded): Only unregister if both the type
          and attribute are clear of needing registration.
