Invent a new memory context primitive, MemoryContextSetParent.
This function will be useful for altering the lifespan of a context after
creation (for example, by creating it under a transient context and later
reparenting it to belong to a long-lived context). It costs almost no new
code, since we can refactor what was there. Per my proposal of yesterday.
