        * html/HTMLMediaElement.cpp:
        (WebCore::HTMLMediaElement::HTMLMediaElement): Initialize m_completelyLoaded.

        (WebCore::HTMLMediaElement::setNetworkState): Don't post 'load' event.

        (WebCore::HTMLMediaElement::userCancelledLoad): No more NETWORK_LOADED state.
        * html/HTMLMediaElement.h:

        * media/audio-delete-while-slider-thumb-clicked.html: Trigger test on 'canplaythrough'
        instead of 'load'.
        * media/audio-delete-while-step-button-clicked.html: Ditto.
        * media/event-attributes-expected.txt: 
        * media/event-attributes.html: Correct logic to check that 'progress' event(s) are
        fired while loading file, but not when src set to invalid file. 'abort' event is fired when
        the src is changed.
        * media/invalid-media-url-crash-expected.txt:
        * media/media-constants-expected.txt: No more NETWORK_LOADED state.
        * media/media-constants.html:  No more NETWORK_LOADED state. Clean up test.
        * media/remove-from-document-expected.txt:
        * media/remove-from-document.html: Ditto.
        * media/video-controls-visible-audio-only.html: Trigger test on 'canplaythrough'
        instead of 'load'.
        * media/video-source-none-supported-expected.txt: No more NETWORK_LOADED state.
        * media/video-src-change-expected.txt: Ditto.
        * media/video-src-none-expected.txt:
        * media/video-src-none.html: No more NETWORK_LOADED state. Fix bogus test that generated
        "FAIL" in results.
