Previously, this was notionally used only for the entry point of the tree and as a convenient parent for other contexts. For shared memory, the creator previously allocated the entry point in this context, but attaching backends didn't have access to that, so they just used the caller's context. For the sake of consistency, allocate every instance of an entry point in the caller's context. For local memory, allocate the control object in the caller's context as well. This commit also makes the "leaf context" the notional parent of the child contexts used for nodes, so it's a bit of a misnomer, but a future commit will make the node contexts independent rather than children, so leave it this way for now to avoid code churn. The memory context parameter for RT_CREATE is now unused in the case of shared memory, so remove it and adjust callers to match. In passing, remove unused "context" member from struct TidStore, which seems to have been an oversight.
