nixos/testing: Improve quality of OCR
First of all, we're now using ImageMagick to improve the screenshot so
that Tesseract has an esier time to recognize the text. The resulting
image of this post-processing is a scaled up black-and-white version
with the backgrounds almost entirely removed and the text edges a bit
blurred, so the screen shots now more or less resemble an image from a
scanner rather. This is what Tesseract is trained for by default.

As mentioned in the previous commit we now also use Tesseract 4, which
further improves the quality of text recognition.

I've spent countless hours just to test different postprocessing
variants and testing what works best for our tests and this is the one
that worked best so far. It's certainly not perfect and I'd like to
avoid the scaling step but we're way better off than before.

In addition to this, the OCR process is now done without an intermediate
file, solely using pipes.

I've tested this using the following VM tests which have OCR enabled:

 * nixos/tests/chromium.nix -A stable
 * nixos/tests/emacs-daemon.nix
 * nixos/tests/installer.nix -A luksroot
 * nixos/tests/lightdm.nix
 * nixos/tests/plasma5.nix
 * nixos/tests/sddm.nix

All of the tests still succeed and comparing some of the recognition
results to the earlier results it now also detects a lot more text than
before this commit.

nixos/test-driver/Logger: Replace invalid UTF-8
Regression introduced by d84741a4bf.

The mentioned commit actually is a good thing, because we now get the
output from the X session.

Unfortunately, for the i3wm test, the i3-config-wizard prints out the
raw keyboard symbols directly coming from xcb, so the output isn't
necessarily proper UTF-8.

As the XML::Writer already expects valid UTF-8 input, we assume that
everything that comes into sanitise() will be UTF-8 from the start. So
we just decode() it using FB_DEFAULT as the check argument so that
every invalid character is replaced by the unicode replacement
character:

https://en.wikipedia.org/wiki/Specials_(Unicode_block)#Replacement_character

We simply re-oncode it again afterwards and return it, so we should
always get out valid UTF-8 in the log XML.

For more information about FB_DEFAULT and FB_CROAK, have a look at:

nixos/test-driver: Make tesseract OCR optional.
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.

nixos/test-driver: Add new waitForText function.
As promised in the previous commit, this can be used similarly to
$machine->waitForWindow, where you supply a regular expression and it's
retrying OCR until the regexp matches.

nixos/test-driver: Add new getScreenText function.
Basically, this creates a screenshot and throws tesseract at it to
recognize the characters from the screenshot. In order to produce a
result that is well enough, we're using lanczos scaling and scale the
image up to 400% of its original size.

This provides the base functionality for a new Machine method which will
be called waitForText. I originally had that idea long ago when writing
the VM tests for VirtualBox and Chromium, but thought it would be
disproportionate to the case.

The downside however is that VM tests now depend on tesseract, but given
the average runtime of our tests it really shouldn't have a too big
impact and it's only a runtime dependency after all.

Another issue is that the OCR process takes quite some time to finish,
but IMHO it's better (as in more deterministic) than to rely on sleep().

Bjørn Forsman 8e8f95beda nixos/test-reports: use local copy of jquery
The current way test reports get jquery,

  src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"

only works when getting reports over http:// or https://, not file://.
Change it so that it works for all protocols by using a local copy of
jquery.

This fixes the issue where locally created and browsed test reports
cannot be navigated properly; clicking the '+' symbol to expand
sub-sections doesn't work.
