Actors in the upside down may communicate with each other, but not the outside
world. However, the outside world can see what actors in the upside-down are
saying. The intention is to use this facility for testing.

Accept toplevel action-producing expressions yielding 0 values.
...
A recent change to Racket must have changed the way `for` expands,
because now in conjunction with `local-expand`, we see *effectively* a
`(begin (values) (void))`. This isn't a problem usually, but in
`#lang syndicate`'s `module-begin` context, we split apart `begin`s
and examine their constituents, leading to examination of something
that will ultimately yield 0 values.
The change accepts either 0 or 1 values when collecting actions for
the module's main boot actor to execute. More than 1 value yielded by
such an expression is still considered an error. Currently, it gives
unhelpful error location information; a future refinement might be to
make the error reporting for this (rare) situation more helpful.

This means that `*gc-priority*` scripts will now reliably run last.
Prior to this change, if some higher-priority script X ran while a
`*gc-priority*` script Y was queued, and it enqueued a high-priority
script Z, then Y would run before Z.

Split dataspaces in to relay and mux sublayers.
...
This is a major change to the previous design, and also a change with
respect to the semantics in the ESOP 2016 paper. All the complexity of
echo-cancellation is stripped out of the core dataspace semantics, and
the relaying protocol is changed from one constructor, `at-meta`, to
two, `inbound` and `outbound`. The relay connecting a dataspace to its
container is now completely symmetric with the contained actors: it
initially asserts interest in what it is to relay, just like any other
actor would. Dataspaces no longer treat relaying specially.
This commit has updated all (I think) of the non-graphical examples. The
graphical code remains to be done in a following commit.
