        Seeking related fixes, updates match to the latest specification
        - rename loopCount of HTMLMediaElement to playCount
        - add explicit seeking attribute to HTMLMediaElement to get semantics right
        - implement the specification behavior that currentTime must immediately return seeked position in HTMLMediaElement
          instead of MoviePrivateQTKit
        - fix broken behavior when seeking past end of the media, add tests
        - replace Movie didEnd callback with broader timeChanged callback (which gets called in didEnd case too)
        - use setDelayCallbacks: in various MoviePrivateQTKit methods to avoid bug prone synchronous callbacks from QT, make
          HTMLMediaElement not depend on synchronous callbacks
        - do some cleanups and simplifications in MoviePrivateQTKit, get rid of m_rateBeforeSeek and m_blockStateUpdate variables

        Seeking related test updates
        - update to match specificiation
            - rename loopCount to playCount everywhere
            - timeupdate events during seek
        - fix that some tests (like audio ones) depended on timing sensitive ordering of play and load events
        - add text about what is being tested

        Add new tests for seeking past end, seeking past loaded position and 'seeking' DOM attribute.
