needs the mesa setup in /run/opengl-driver

This required some changes to systemd unit handling:
* Add an option to specify that a unit is just a symlink
* Allow specified units to overwrite systemd-provided ones
* Have gettys.target require autovt@1.service instead of getty@1.service

This is a second attempt at unifying the generic and manual-config
kernel builds (see #412 for the last time).
The set of working kernel packages is a superset of those that work on
master, and as the only objection last time was the size of the $dev
closure and now both $out and $dev combined are 20M smaller than $out on
master (see message for ac2035287f), this
should be unobjectionable.

In most cases, this just meant changing kernelDev (now removed from
linuxPackagesFor) to kernel.dev. Some packages needed more work (though
whether that was because of my changes or because they were already
broken, I'm not sure). Specifics:
* psmouse-alps builds on 3.4 but not 3.10, as noted in the comments that
were already there
* blcr builds on 3.4 but not 3.10, as noted in comments that were
already there
* open-iscsi, ati-drivers, wis-go7007, and openafsClient don't build on
3.4 or 3.10 on this branch or on master, so they're marked broken
* A version-specific kernelHeaders package was added
The following packages were removed:
* atheros/madwifi is superceded by official ath*k modules
* aufs is no longer used by any of our kernels
* broadcom-sta v6 (which was already packaged) replaces broadcom-sta
* exmap has not been updated since 2011 and doesn't build
* iscis-target has not been updated since 2010 and doesn't build
* iwlwifi is part of mainline now and doesn't build
* nivida-x11-legacy-96 hasn't been updated since 2008 and doesn't build
Everything not specifically mentioned above builds successfully on 3.10.
I haven't yet tested on 3.4, but will before opening a pull request.

The difference between xsession and xprofile is that xsession is exec'd and xprofile is sourced.
So with xprofile all commands after sourcing will still be exectued. This allows for instance
autostarting of applications while configuring the start of a window manager via configuration.nix.
This patch adds support for the creations of new bond devices, aggregate
pipes of physical devices for extra throughput or failover.
Additionally, add better correction at the startup of a bridge
of vlan interface (delete old, stale interfaces).
The redshift service stops working after some time (the program exits
after some hours/days). It looks like these exits are related to calls
to xrandr (for multiple displays) or suspend-to-ram.

PR #1366
The previous windowManager.xmonad option only starts xmonad and
doesn't make ghc available. This assumes that the user has GHC with
access to the xmonad package in his PATH when using xmonad.
Xmonad in Nix is now patched to accept the XMONAD_{GHC,XMESSAGE}
environment variables which define the path to either ghc or xmessage.
These are set automatically when using xmonad through
windowManager.xmonad.
My (or specific: @aristidb and my) changes make it possible to use
Xmonad without adding GHC to any profile. This is useful if you want
to add a different GHC to your profile.
This commit introduces some options:
- xmonad.haskellPackages: Controls which Haskell package set & GHC set
is used to (re)build Xmonad
- xmonad.extraPackages: Function returning a list of additional
packages to make available to GHC when rebuilding Xmonad
- xmonad.enableContribExtras: Boolean option to build xmonadContrib
and xmonadExtras.

ntopng is a high-speed web-based traffic analysis and flow collection
tool. Enable it by adding this to configuration.nix:
services.ntopng.enable = true;

Postgres was taking a long time to shutdown. This is because we were
sending SIGINT to all processes, apparently confusing the autovacuum
launcher. Instead it should only be sent to the main process (which
takes care of shutting down the others).
The downside is that systemd will also send the final SIGKILL only to
the main process, so other processes in the cgroup may be left behind.
There should be an option for this...
You can now say:
systemd.containers.foo.config =
{ services.openssh.enable = true;
services.openssh.ports = [ 2022 ];
users.extraUsers.root.openssh.authorizedKeys.keys = [ "ssh-dss ..." ];
};
which defines a NixOS instance with the given configuration running
inside a lightweight container.
You can also manage the configuration of the container independently
from the host:
systemd.containers.foo.path = "/nix/var/nix/profiles/containers/foo";
where "path" is a NixOS system profile. It can be created/updated by
doing:
$ nix-env --set -p /nix/var/nix/profiles/containers/foo \
-f '<nixos>' -A system -I nixos-config=foo.nix
The container configuration (foo.nix) should define
boot.isContainer = true;
to optimise away the building of a kernel and initrd. This is done
automatically when using the "config" route.
On the host, a lightweight container appears as the service
"container-<name>.service". The container is like a regular NixOS
(virtual) machine, except that it doesn't have its own kernel. It has
its own root file system (by default /var/lib/containers/<name>), but
shares the Nix store of the host (as a read-only bind mount). It also
has access to the network devices of the host.
Currently, if the configuration of the container changes, running
"nixos-rebuild switch" on the host will cause the container to be
rebooted. In the future we may want to send some message to the
container so that it can activate the new container configuration
without rebooting.
Containers are not perfectly isolated yet. In particular, the host's
/sys/fs/cgroup is mounted (writable!) in the guest.
