(Whiteboard: [rm-docshell-tree-item:hard])

This code calls OnPageHide() and OnPageShow() respectively, on all children which are descendents of the current docshell tree item.

This is called from frame-swapping code only (when loaders are being swapped) it seems. This method should be left alone, but the frame-loading code needs to be changed to call this method on each fragment individually.

Subsequently, this method should be renamed to document the fact that it only performs on the in-process fragment of the docshell tree.
