this is not necessary in any way, but it will make the following changes
smaller and easier to review. the aliases could also be added piecemeal,
but doing it here lets us lean heavily on our compilers for correctness.
(teacher notes: here the author foreshadows the shape of things to come.
not all names change, and only the names unchanged are those which will,
over time, become ever more unrecognizable. note especially nix/main.cc,
where `state` is not only cloned, but itself changes pointerness. it can
be seen as a nod to the trans community, but more realistically it is no
more than foreshadowing the future where `state` is only seen by proxy.)

Today, with the tests inside a `tests` intermingled with the
corresponding library's source code, we have a few problems:
- We have to be careful that wildcards don't end up with tests being
built as part of Nix proper, or test headers being installed as part
of Nix proper.
- Tests in libraries but not executables is not right:
- It means each executable runs the previous unit tests again, because
it needs the libraries.
- It doesn't work right on Windows, which doesn't want you to load a
DLL just for the side global variable . It could be made to work
with the dlopen equivalent, but that's gross!
This reorg solves these problems.
There is a remaining problem which is that sibbling headers (like
`hash.hh` the test header vs `hash.hh` the main `libnixutil` header) end
up shadowing each other. This PR doesn't solve that. That is left as
future work for a future PR.
