        [Gtk] media/video-reverse-play-duration.html fails on and off on Gtk buildbots
        https://bugs.webkit.org/show_bug.cgi?id=34086

        Cache media duration and fix didEnd() in case of reverse
        playback. When EOS was reached but in case of reverse playback the
        position is not always 0. So to not confuse the HTMLMediaElement
        we synchronize position and duration values.

        * platform/graphics/gtk/MediaPlayerPrivateGStreamer.cpp:
        (WebCore::MediaPlayerPrivate::MediaPlayerPrivate):
        (WebCore::MediaPlayerPrivate::duration):
        (WebCore::MediaPlayerPrivate::updateStates):
        (WebCore::MediaPlayerPrivate::didEnd):
        (WebCore::MediaPlayerPrivate::durationChanged):
        * platform/graphics/gtk/MediaPlayerPrivateGStreamer.h:
