        A <source> element inserted as a child of a media element with a networkState of NETWORK_EMPTY
        should cause the networkState to immediately change to NETWORK_NO_SOURCE.

        * WebCore.xcodeproj/project.pbxproj:
        * html/HTMLMediaElement.cpp:
        (WebCore::HTMLMediaElement::HTMLMediaElement): Remove unused variable m_processingLoad.
        (WebCore::HTMLMediaElement::prepareForLoad): Set m_networkState to NETWORK_NO_SOURCE.
        (WebCore::HTMLMediaElement::loadInternal): Remove unused variable m_processingLoad.
        (WebCore::HTMLMediaElement::selectMediaResource): No need to change m_networkState, it was done in prepareForLoad.
        * html/HTMLMediaElement.h:

        * html/HTMLSourceElement.cpp:
        (WebCore::HTMLSourceElement::insertedIntoTree): Renamed from insertedIntoDocument because we want
        to do this setup whether or not the parent media element is in the document.
        * html/HTMLSourceElement.h:
