Ingo Weinhold a0747aad3b After the first call to BView::InvalidateLayout() further invocations don't
invoke the layout's InvalidateLayout() anymore. This could cause problems when
the layout caches layout related information and also updates those on calls
other than LayoutView(). A call to such a method after an InvalidateLayout()
would mark the cached info valid and the layout would use the cached info
until the first InvalidateLayout() after the next LayoutView(), even if
BView::InvalidateLayout() had been called again in the meantime.

* Introduced a new method BView::ResetLayoutInvalidation(), which must be
  called by layout implementations whenever they have updated their cached
  information and need further InvalidateLayout() notifications.
* Adjusted the existing layout implementations to use the method.

Fixes bug #4047.
