gnu: Fix (evaluation of the) call to forceSystem.
Partially revert 7a45996 some more.

Removing more references to the non-existent license "stdenv.lib.licenses.perl5".
Thanks to @FlashKorten for catching those.
libtoxcore: Update to latest Git master.

The GitHub repository has changed the name to "toxcore".
Also indented buildInputs/configureFlags a bit less messy.

libtoxcore: Add libopus and libvpx to buildInputs.

Those are necessary to do audio/video calls, which I guess is the whole
point of the Tox project.

libtoxcore: Enable and fix up running test suite.

We not only require libcheck but also needed to disable a few tests,
without providing the former, test cases were signalled as being run
successfully but weren't actually run.

toxic: Update to latest upstream Git master.

Unfortunately they've changed their build system to be makefile-only and
they don't seem to include test cases in the CLI anymore, so we needed
to adapt accordingly. Also added freealut and openal to the buildInputs,
in order to allow audio support.

freealut: Clean up expression and add meta.

Upgrade docker to 1.1.2 and add docker module

This version of module has disabled socketActivation, because until
nixos upgrade systemd to at least 214, systemd does not support
SocketGroup. So socket is created with "root" group when
socketActivation enabled. Should be fixed as soon as systemd upgraded.

Includes changes from #3015 and supersedes #3028
initrd: Include filesystem support for /nix, /var etc.
Add activationScript for TrackPoint configuration
SimpleScreenRecorder 0.2.2 -> 0.3.0
python-wrapper: Fix handling __future__ imports.

The bazaar package is still broken even with 5f01cc7, because __future__
imports need to be the first imports before anything else. So this time
I'm going to make the sed expression with explicit branching so we can
properly match all the occasions we want to skip and insert the line
modifying sys.argv[0] only _once_ and leave the command block after
that one substitution. So no ugly swaps between hold and pattern space.

The label which is resonsible for not escaping the command block is "r"
and we jump to it as long as we need to skip something from the start of
the file.

While at it, I'm not only skipping every line with __future__ in it but
also backslashes at the end of the line, so for example:

```python
from __future__ import shiny_feature1, \
                       shiny_feature2, \
                       shiny_feature3
```

... will now be properly skipped as well.

Tested against bazaar and nixops.

Thanks to @edolstra for reporting this.

python-wrapper: Fix handling of line breaks.

Not really critical for anything we have in <nixpkgs> I guess, but
skipping lines three times really was a workaround and we're better off
just appending the lines ending with backslash to the pattern space so
we can accumulate all the crap until the last line of crap (crap, that
is "broken lines").
