Put the JunkFilter and its result slot (and thence also some subsidiary data such as the result tupledesc) into a separate subcontext "jfcontext". This doesn't accomplish a lot at this point, because we make a new JunkFilter each time through the SQL function. However, the plan is to make the fcontext long-lived, and that raises the possibility that we'll need a new JunkFilter because the plan for the result-generating query changes. A separate context makes it easy to free the obsoleted data when that happens. Also, instead of always running the sub-executor in fcontext, make a separate context for it if we're doing lazy eval of a SRF, and otherwise just run it inside CurrentMemoryContext.
