By default this is now enabled, and it has to be explicitely enabled
using "enableOCR = true". If it is set to false, any usage of
getScreenText or waitForText will fail with an error suggesting to pass
enableOCR.
This should get rid of the rather large dependency on tesseract which
we don't need for most tests.
Note, that I'm using system("type -P") here to check whether tesseract
is in PATH. I know it's a bashism but we already have other bashisms
within the test scripts and we also run it with bash, so IMHO it's not a
problem here.

Fixes the "blindly hope that 60 seconds is enough" issue from 1f34503,
so that we now have a (hopefully) reliable way to wait for the

This serves as a regression test for #7859.
It's pretty straightforward, except from the fact that nixos-generate-
config doesn't detect LUKS devices and the "sleep 60".
As for the former, I have tried to add support for LUKS devices for
nixos-generate-config, but it's not so easy as it sounds, because we
need to create a device tree across all possible mappers and/or LVM up
to the "real" device and then decide whether it is relevant to what is
currently mounted. So I guess this is something for the nixpart branch
(see #2079).
And the latter isn't very trivial as well, because the LUKS passphrase
prompt is issued on /dev/console, which is the last "console=..." kernel
parameter (thus the `mkAfter`). So we can't simply grep the log, because
the prompt ends up being on one terminal only (tty0) and using select()
on $machine->{socket} doesn't work very well, because the FD is always
"ready for read". If we would read the FD, we would conflict with
$machine->connect and end up having an inconsistent state. Another idea
would be to use multithreading to do $machine->connect while feeding the
passphrase prompt in a loop and stop the thread once $machine->connect
is done. Turns out that this is not so easy as well, because the threads
need to share the $machine object and of course need to do properly
locking.
In the end I decided to use the "blindly hope that 60 seconds is enough"
approach for now and come up with a better solution later. Other VM
tests surely use sleep as well, but it's $machine->sleep, which is bound
to the clock of the VM, so if the build machine is on high load, a
$machine->sleep gets properly delayed but the timer outside the VM won't
get that delay, so the test is not deterministic.
Tested against the following revisions:
5e3fe39: Before the libgcrypt cleanup (a71f78a) that broke cryptsetup.
69a6848: While cryptsetup was broken (obviously the test failed).
15faa43: After cryptsetup has been switched to OpenSSL (fd588f9).

These commands will be executed directly after the machine is created,
so it gives us the chance to for example type in passphrases using the
virtual keyboard.

It seems like there's an upstream bug in the "lpstat" command. We need

Sometimes, keys aren't properly recognized the first time, so in order
to make sure they get through, always resend the key again on retry.
In this case the worst that could happen is that the VM is started over
and over again, but never in parallel, so that's fine because we're
checking for successful startup 10 seconds after the keypress.

It's not nice to send the escape key over and over again just to ensure
the popup is closed, because even *if* it fails to close the popup 4
times in a row it's just very unlikely that it will be closed. But in
order to make really sure, we might need to do a screenshot and detect
visual changes.

I'm increasing it to 100MB to make sure, any bootloader will fit with
all its stages. Of course, right now the reason why GRUB doesn't fit
into the partition is because of mdadm 3.3.2 and thus the initrd taking
all the space, but in order to avoid confusion on why the *boot* loader
fails in the VM tests, I've increased the size.

Currently just makes sure that by default it's possible to open a
terminal.
And exactly this should be the main point that might confuse users of i3
in NixOS, because i3 doesn't print a warning/error if it is unable to
start the terminal emulator.
Thanks to @waaaaargh for reporting this issue.

Since Chromium version 42, we have a new user namespaces sandbox in the
upstream project. It's more integrated so the chrome://sandbox page
reports it as "Namespace Sandbox" instead of SUID sandbox, which we were
re-using (or abusing?) in our patch.
So if either "SUID Sandbox" or "Namespace Sandbox" reports with "Yes",
it's fine on our side.

Chromium is quite memory hungry and we frequently get random crashes in
the tests, so let's set it to 1024 MB because new releases of Chromium
most probably won't consume *less* memory.

Especially if the user isn't in the vboxusers group anymore, this gets
VERY noisy, because the VBoxSVC process emits warnings for every single
USB device noting that it's only possible to access it when the user is
in the vboxusers group.
So, we now have a debug attribute, where we can enable it when
necessary.

The "nix-store" command within the VM test is running without
NIX_REMOTE=daemon and since Nix 1.8 tries to open the store database in
read-write mode even for nix-store -qR.
Now, we're doing this properly and rely on setup hooks, which is the
same method that's used when you're building a library which depends on
blivet.

Essentially adds two more VirtualBox VMs to the test and also increases
the memory size of the qemu VM to 768 MB to make sure we don't run out
of memory too soon.
We're testing whether those two VMs can talk to either each other
(currently via ICMP only) or to/from the host via TCP/IP.
Also, this restructures the VM test a bit, so that we now pass in a
custom stage2Init script that has access to the store via a private
mount over the /nix/store that's already in the initrd. The reason why
this is a private mount is that we don't want to shadow the Nix store of
the initrd, essentially breaking cleanup functionality after the custom
stage 2 script (currently this is only "poweroff -f").
Note that setting the hostname inside the VirtualBox VM is *not* for
additional fanciness but to produce a different store path for the VM
image, so that VirtualBox doesn't bail out when trying to use an image
which is already attached to another VM.
