        Call didSendData as body data is uploaded to the server. This is necessary
        for XHR upload events to function properly.

        * platform/network/ResourceHandleInternal.h:
        (WebCore::ResourceHandleInternal::ResourceHandleInternal): Add two new members.
        One to track the total amount of body data and one to track the total amount of
        body data sent so far.
        * platform/network/soup/ResourceHandleSoup.cpp:
        (WebCore::wroteBodyDataCallback): Added.
        (WebCore::addFormElementsToSoupMessage): Split this out into a helper function.
        Will now now sum the total amount of body data.
        (WebCore::startHttp): Attach a wrote-body-data signal handler.
