This ensures that the intermediate machine is shut down only after the
migration has finished writing the memory dump to disk, to ensure we
don't end up with empty state files depending on how fast the migration
finished before we actually shut down the VM.

This ensures that the builder isn't waiting forever if the Windows VM
drops dead while we're waiting for the controller VM to signal that a
particular command has been executed on the Windows VM. It won't ever
happen in such cases so it doesn't make sense to wait for the timeout.

So far, we determined this based on stdenv.is64bit, but there are cases
where you want to run/build a 32bit program on a 64 bit Windows.
This is now possible, by passing windowsImage.arch = "i686" | "x86_64"
to runInWindowsVM. Based an what was passed, the corresponding Cygwin
packages and setup.exe are bootstrapped.

Another very annoying part. Unfortunately, the only option we might have
here is to include it in nixpkgs or maybe make a fixed Hash on the
result of the closure fetcher.

As the official Cygwin setup binary download doesn't come in snapshots
or even versioned, the fetchurl of setup.exe will frequently fail, which
in turn will annoy us as hell (or at least me).
One warning though: The fetchurl is currently broken and the cross-build
might not work yet for example on mingw32 (mingw-w64 branch on its way),
but the upstream URL has already changed and the new version contains a
bug (not yet tracked down) which breaks our Windows bootstrap process.
So to conclude: If it's already broken, make it at least "less broken".
"Not broken" is coming soon with the merge of the mingw-w64 branch.

Coincidentally, even with this typo, most tests work anyway, so I didn't
notice it in the first place.

Also update 64bit setup.ini and check whether we have a 64 bit stdenv in
order to choose the proper Cygwin version. Otherwise we now have the
setup.ini for 32bit available as well.

So far, the VMs have always been using the native architecture, because
it was reimporting <nixpkgs> several times. Now, we propagate a list of
packages down to all sub-imports, which not only makes clearer which
dependencies a part actually has, but also will make it easier in case
we want to refactor those parts to use callPackage.

This now isolates the vmTools integration from the bootstrap process and
thus removes our fixed Windows ISO and product key. The latter can now
be provided by an attribute "windowsImage" to runInWindowsVM.
