Brief update. The scope of this change has shrunk considerably. The
deferred loading and migrations stuff still applies, but the main
user-facing aspect, namely, support for let-binding a module's options
on entry-point invocation, has been abandoned (for now).

After looking into connection-local variables a bit, following Michael's
suggestion up thread, I have come to the opinion that the let-binding
idea was not fully formed and that options granularity is worthy of more
meditation and discussion and thus not a realistic goal for Emacs 5.5.

Thanks.
