The main change here is a patch of SLiM to tread a log file of
/dev/stderr specially in that it now uses std::cerr instead of a file
for logging.
This allows us to set the logfile to stderr in NixOS for the generated
SLiM configuration file and we now get logging to the systemd journal.

The idea is to provide a convenient way to enable most vanilla hardening
features in one go. The hardened profile, then, will serve as a place for
features that enhance security but cannot be enabled for all deployments
because they interfere with legitimate use cases (e.g., using ptrace to
debug problems in an already running process).

This reverts commit 6b7c5ba535.
Unfortunately it seems like this broke slim, lightdm and gdm (see #25068
and #23264). This is already reverted in the 17.03 branch (99dfb6d).
TODO: We need tests for slim and lightdm and fix the test for gdm
(failing since 2016-10-26) to prevent such breakage in the future.
This has surfaced since d990aa7163.
The "simpleUefiGummiboot" installer test fails since this commit,
because that commit introduced a small check to verify whether the store
was altered.
While installing NixOS for the first time, the store is usually in
/mnt/nix/store and without the read-only bind mount that's preventing
programs from altering the store.
So after nixos-install is done creating the system closure and setting
it as the active system profile, the bootloader is written from the
closure inside the chroot. The systemd-boot-builder is invoked during
this step, which adds .pyc files for various Python modules of the
Python 3 store path, which in turn invalidates the hash of the Python 3
store path itself.
At the time the system is booted up again, the nix-store is verified and
fails with something like this:
path /nix/store/zvm545rqc4d97caqq9h7344bnd06jhzb-python3-3.5.3 was
modified! expected hash

This reverts commit c2b56626f1.
It broke creating the manual. I suspect the descriptions are
auto-wrapped by <para> and </para>.
We've been through this already in 3af715af90.
/cc #24978, @zraexy, @Mic92.
The key distinction I'm drawing is that there's a component that deals
with the store of the machine being built, and another component for
the store building it. The inner part of it assumes nothing from the
builder (doesn't need chroot or root powers) so it can run comfortably
inside a Nix build, as well as nixos-rebuild. I have some upcoming work
that will use that to significantly speed up and streamline image builds
for NixOS, especially on virtualized hosts like EC2, but it's also a
reasonable speedup on native hosts.
bluez no longer recommends spawning "hciconfig <device> up" from a udev rule as
the main bluez daemon now supports automatically enabling power for all devices.

This change fixes two major issues:
1. If you don't use SIGQUIT to stop Plex it will corrupt its own
database :(
2. Newer versions of Plex keep metadata in the
`com.plexapp.plugins.library.db` database. This is the file that
we copy into `/var/lib/plex/.skeleton`. If we copy the empty
database on top of this one the user will lose their entire
library metadata. This change skips the copy if the file
already exists.
* google-cloud-sdk: 150.0.0 -> 151.0.0
- gce/create-gce.sh: rewrite using nix-shell shebang and bash
- allows to run the script without being the same directory
- nix-shell install google-cloud-sdk
- some shellcheck cleanups and scripting best practice
- gce/create-gce.sh: do not clobber NIX_PATH: this allows NIX_PATH to be overwritten to build a different release
- gce/create-gce.sh: remove legacy hydra option
This allows gitweb to expand '~' in /etc/gitconfig. Without a $HOME
variable, it fails to list any projects and instead show the text
"No such projects found" in the UI.
Setting $HOME to the gitweb project root seems like a sensible value.
This reverts commit 0a6a06346a.
The commit replaced the text to search for from ALICE to BOB, because
our OCR detection only caught "BOB FOOBAR" but missed "ALICE FOOBAR"
completely.
With the improvements to our OCR system this no longer is the case and
the test passes successfully with this reverted.

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.

I've removed that attribute in 68bc260ca2,
because the language files no longer were distributed as seperate files,
but if we for example only want to use the English training data, the
closure size of Tesseract gets quite large (around 1.2 GB), which is a
bit much just to be able to run NixOS VM tests.
For this reason I've also switched the VM tests back to using only the
English language.
Tested using the following VM tests (the ones that have OCR enabled) on
x86_64-linux:
* 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
