Implement GuC parent-child context pin / unpin functions in which in any contexts in the relationship are pinned all the contexts are pinned. The parent owns most of the pinning / unpinning process and the children direct any pins / unpins to the parent.
Patch implements a number of unused functions that will be connected later in the series.
