Source/WebKit/qt:

Disable REQUEST_ANIMATION_FRAME_TIMER for the Qt port and tie
the servicing of scripted animations to the renderNextFrame call for WK2.
For WK1 we rely on the RefreshAnimation that is based on QAbstractAnimation.

* WebCoreSupport/ChromeClientQt.cpp:
(RefreshAnimation):
    Add a RefreshAnimation that is based on QAbstractAnimation
    and drives the servicing of the scripted animations for WK1.
(WebCore::RefreshAnimation::RefreshAnimation):
(WebCore::RefreshAnimation::duration):
(WebCore::RefreshAnimation::scheduleAnimation):
    Set m_animationScheduled to true and start the animation
    timer in case it is not running yet.
(WebCore::RefreshAnimation::updateCurrentTime):
    Call serviceScriptedAnimations if m_animationScheduled is true.
    If this is not the case, the animation timer can be stopped,
    because no animation needs to be scheduled anymore.
(WebCore):
(WebCore::ChromeClientQt::scheduleAnimation):
    Create and start the RefreshAnimation instance with the
    first call to scheduleAnimation.

Source/WebKit2:
