WebFoundation:

        Changes to support submission of forms using HTTP POST.

        These changes focus on adding the form data to a post request.

        addRequestMessageBody:]):
        * ChangeLog:
        * WebFoundation.pbproj/project.pbxproj:


	WebCore:

        Changes to support submission of forms using HTTP POST.

        These changes move us over to using the new WebKit interface for creating
        WebDataSource instances, one that passes a handle rather than just a URL,
        enabling the specific request method to be communicated to WebFoundation.
        This fixes:

        Radar 2903602 (IFWebDataSource API must passes attributes and flags to IFURLHandle)

        Fixed handling of password fields:

        Radar 2903605 (WebCore form processing drops out password input data)

        Added some hacks to get form <input type=image ...> working correctly:
