The asserting will continue until morale improves! * Convert all assert(*.isNormalized) checks to use the new debugAssertIsNormalized technology. * Convert CustomMultiChildLayout to use the new RenderingError technology to greatly improve the detail in errors you get when writing CustomMultiChildLayout delegates. * Add BoxConstraints.copyWith(). * Indent the descendants in the rendering exception data dump so that when you have multiple children it's clearer what's going on.

The virtual viewport machinery now handles all of these use cases. Previous clients of ScrollableWidgetList can use ScrollableLazyList instead.

This patch moves PageableList off HomogeneousViewport and onto RenderList and friends, making it match the new ScrollableList.

This patch also changed ScrollableList2 to use an Iterable instead of an List for its children. This change lets clients map their underlying data lazily. If the clients actually have a concrete list, we skip the extra copy and grab the child list directly.

This patch implements the remaining missing features of ScrollableList2. It should now be nearly a drop-in replacement for ScrollableList. The next patch will switch callers over to the new machinery.

ScrollableList2 uses the same pattern as ScrollableGrid, which requires the client to allocate widgets for every list item but doesn't inflate them unless they're actually needed for the view. It improves on the original ScrollableList by not requiring a rebuild of the whole visible portion of the list when scrolling. In fact, small scrolls can often be handled entirely by repainting.
