To prevent multiple Qt libraries when developing with a custom one, the Qt
support can now be activated by directly supplying the Qt libraries as an
argument (qtLib).
qtSDK and qtFull users/developers now just have to define an override such
as the following one in order to use it inside their development
environment:
vtk.override { qtLib = qt4SDK; };
The previous behavior is still the same for vtk and vtkWithQt4 end-users.

Consider this as a first step towards the integration of Qt5 into nixpkgs,
it does not yet intends to replace Qt4 on every packages even if possible.
My goal here is to have a first derivation in common between people who
needs qt5 for development purposes.
The derivation has been written from scratch but I took care to read at the
version 4 to re-integrate some patches which are still compatible. However,
I did not had enough time to test gtkStyle and flashplayerFix as I do not
use any of them. Also, OSX users will have to do some extra work because
I do not have any mac.
Finally, as some configure flags have changed and in an hope to provide a
clear package definition before it becomes mature, I voluntary added some
flags which are default. Once every option will be mastered, we will just
have to redo a pass on qt5 configure flags and remove the ones which are
set by default.
Apply a fix which prevented to use -DGL_GLEXT_LEGACY, -Werror and -Wundef
to be used together. This produced a build fail on any software meeting
these requirements.
To give the ability to use a different Qt version than the default one
(which can build 3 different times Qt Libraries if we mixed the default
one, the qtcreator one and the version including all the examples and the
docs).
Right now a developer can choose to directly install the QtSDK which
includes a "full" (developerBuild + docs + examples) Qt version and uses
it to build QtCreator.
The possibility to only install QtCreator and its previous behavior has
been kept for flexibility purposes (we do not need to force someone on the
SDK approach).
It requires a writable /nix/store to store the build result. Also,
wait until we've reached multi-user.target before doing the build, and
do a sync at the end to ensure all data to $out is properly written.

Suggested by Marc Weber. Fixes#1059.
Generate /etc/nix.machines only if buildMachines is not empty. Thus,
if you want to manage /etc/nix.machines in some other way, you can set
nix.distributedBuilds to true but not set nix.buildMachines.
Note that there is a subtle difference in Nix that causes
nixos-rebuild to work and NixOps to fail:
$ nix-instantiate '<nixos>' -A config.system.nixosVersion --eval-only
"13.10pre34915.50f4822"
$ nix-instantiate '<nixos/default.nix>' -A config.system.nixosVersion --eval-only
error: opening file `/nix/var/nix/profiles/per-user/root/channels/nixos/.version': No such file or directory
FixesNixOS/nixops#145.
Sshd *must* use PAM because we depend on it for proper session
management. The original goal of this option (disabling password
logins) can also be implemented by removing pam_auth authentication
from sshd's PAM service.
That is, you can say
security.pam.services.sshd = { options... };
instead of
security.pam.services = [ { name = "sshd"; options... } ];
making it easier to override PAM settings from other modules.
Previously logging in via SLiM more than once didn't work because SLiM
doesn't clean up its PAM session properly (that is, in a child rather
than in the parent). Thus the slim process becomes part of the user
session's cgroup, among other things. This patch causes SLiM to exit
after the session has finished, after which systemd will restart
display-manager.service.
FixesNixOS/nixops#137.
