Mathijs Kwik b21853f255 Fix initrd breaking by recent repeatable-builds changes
See the comments at f67015cae4
for more information.

Please note: this makes initrd unrepeatable again, but most people will prefer that above an unbootable system.

Bjørn Forsman 25f0b7cb50 gcc-{,cross-}wrapper: add 'cpp' wrapper (close #1820)
The gcc-wrapper doesn't wrap 'cpp'. This breaks some software (such as
Buildroot) because the 'cpp' they get come from the non-wrapped gcc
package which doesn't know about any standard include paths.

gcc-cross-wrapper is untested.

vm/windows: Allow to specify a different arch.
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.

vm/windows: Replace binary with cross cygwinSetup.
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.

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.

vm/windows: Add new runInWindowsVM function.
This function is quite similar to runInLinuxVM, but also ensures that
the builder is run decoupled of the Nix store and using the userland
inside the VM.

We're now picking up the environment variables saved in the previous
commit.

The reason we suppress all errors from the source operation is that it
would emit a ton of errors because we're trying to set read-only
variables.

Also, detecting whether the origBuilder is using the default builder
from the stdenv is currently a bit of a workaround until we have a
specialized pseudo-cross-stdenv someday in the future[TM].

vm/windows: Save envirenoment before running VM.
Later, when we start the actual builder, we're going to restore those
environment variables. We're using "(set; declare -p)", here, because
the former is just printing _all_ environment variables, even those not
supported, and the latter only lists specifically declared variables,
which also encludes exports.

The "declare -p" command also emits those variables in a format similar
to the "export" command.

vm/windows: Fix perms of the Samba shares.
We now map all guest accounts to the root user, because in the end the
permissions of the current user boil down to the build user of the Nix
builder of the host. That way it's not possible to gain more permissions
at all and just makes the VM communication a lot easier.

However, setting "writable" to yes instead of "read only" to no doesn't
change anything here, I just found it to be clearer.

Also, we now no longer need to have a "nobody" user.

vm/windows: Avoid shadowing the Nix store.
This is done by putting the non-initrd /nix/store into a subdirectory,
which we then chroot to and pass along the SSH command.

Also, we now collect the exit code after the chroot command and power
off the VM thereafter, because the store is no longer shadowed and we
have still access to the busybox inside the initrd.

vm/windows: Reintroduce setting up /nix/store.
Now we're doing this at the point where we're saving the VM state.
Unfortunately it's not quite right, because the controller VM is shut
down _before_ we're saving the state, so the share gets disconnected
despite autodisconnect being deactivated during setup.

We can get around this issue by finally introducing the xchg share,
which is the last item to be implemented before we can merge to master.

This might look a bit overwhelming, but let me try to explain:

We're starting at the base derivation ("BOOTSTRAP" above), where we
actually install the Cygwin envirenment. Over there we basically fire up
a vde_switch process and two virtual machines: One is the Windows
machine, the other is a NixOS machine, which serves as some kind of
proxy between the host and the Windows machine.

The reason we're doing this, is because we don't have a lot of options
for sharing files between a stock Windows machine and the host. In
earlier experiments, I've tried to communicate with the Windows guest by
using pipes and OpenSSH, but obviously this wasn't a big speed rush (or
to say it bluntly: It was fucking slow).

Using TCP/IP directly for accessing the guest would have been another
option, but it could lead to possible errors when the port or a range of
ports are in use at the Host system. Also, we would need to punch a hole
into the sandbox of the Nix builder (as it doesn't allow networking),
which in turn will possibly undermine deterministic builds/runs (well,
at least as deterministic as it can be, we're running Windows,
remember?).

So, let's continue: The responsibility of the NixOS (controller) VM is
to just wait until an SSH port becomes available on the Windows VM,
whereas the Windows VM itself is installed using an unattended
installation file provided via a virtual floppy image.

With the installation of the basic Windows OS, we directly install
Cygwin and start up an OpenSSH service.

At this point the bootstrapping is almost finished and as soon as the
port is available, the controller VM sets up Samba shares and makes it
available as drive letters within Windows and as bind mounts (for
example /nix/store) within Cygwin.

Finally we're making a snapshot of the memory of the Windows VM in order
to revive it within a few seconds when we want to build something.

Now, the build process itself is fairly straightforward: Revive VM and
build based on existing store derivations and collect the result _and_
the exit code from the xchg share/directory.

Conclusion: This architecture may sound a bit complicated, but we're
trying to achieve deterministic and reproducable builds and/or test
runs.
