        Differentiate between cancelation errors and generic network error in XHR.

        * loader/FrameLoader.cpp:
        (WebCore::FrameLoader::requestFromDelegate):
        (WebCore::FrameLoader::cancelledError):
        * platform/network/ResourceErrorBase.h:
        (WebCore::ResourceErrorBase::setIsCancelation):
        (WebCore::ResourceErrorBase::isCancelation):
        (WebCore::ResourceErrorBase::ResourceErrorBase):
        Add state that differentiates between errors created by cancelation and those made
        by all other generic network errors as this differentiation is needed by some specs.

        * xml/XMLHttpRequest.cpp:
        (WebCore::XMLHttpRequest::open):
        (WebCore::XMLHttpRequest::loadRequestSynchronously):
        (WebCore::XMLHttpRequest::clearResponseEntityBody):
        (WebCore::XMLHttpRequest::genericError):
        (WebCore::XMLHttpRequest::networkError):
        (WebCore::XMLHttpRequest::abortError):
        (WebCore::XMLHttpRequest::didFail):
        * xml/XMLHttpRequest.h:
        * xml/XMLHttpRequestException.h:
        (WebCore::XMLHttpRequestException::):
        * xml/XMLHttpRequestException.idl:
        Add ABORT_ERR. This error cannot be raised with the current WebKit architecture
        as it requires the ability to cancel a synchronous XHR, which we cannot currently
        do.  It may be possible in the future though.

        Update expected results for new ABORT_ERR.
