If cuda headers are presented to nix in $out/include they are added to future gcc calls via a -isystem flag. However, cuda does not allow kernel calls from template function if these are located in system-headers. We thus move headers from $out/include to $out/usr_include and add a custom hook to add these headers via -I.

Add `--no-same-permission` to `tar` command in node package builder

This is because of an error while using `nix` under Archlinux:
```
building path(s) `/nix/store/rwkcbhv9jfhzhandfslg62knl2xw0r7m-node-sources'
building /nix/store/rwkcbhv9jfhzhandfslg62knl2xw0r7m-node-sources
suspicious ownership or permission on `/nix/store/rwkcbhv9jfhzhandfslg62knl2xw0r7m-node-sources'; rejecting this build output
cannot build derivation `/nix/store/01qsszx9y2kyx1x72zr5magy2la98720-uglify-js-2.4.15.drv': 1 dependencies couldn't be built
```

The permissions on all file are like the following:
```
drwxrwxr-x 1 root root    358 Jun  9 17:04 .
drwxr-xr-x 1 root root 421110 Jul 21 15:49 ..
-rw-rw-r-- 1 root root     22 Jun  9 17:04 .gitattributes
```
After the fix, permissions are OK, and no suspicious error any more.

Error is encountered for any node package built. I'm not sure why it
fails on Arch but work on nixos, but I believe the flag is safe to add
anyway.
Added abduco
Changed to correct license from licenses.*
initrd: Fixed to include/use modprobe config files
add note about mutableUsers to user management section
php: Compile pdo_pgsql support
initrd.availableKernelModules: add support for keyboards

As explained in #2169, some keyboards need special drivers,
so these are always added, both on installation and normal systems.
Add thermald: Linux Thermal Daemon
Cleanup: remove newlines.
nixos/network-interfaces: Add sit interfaces

Previously, we had no method for creating 6-to-4 tunneled interfaces.
This patch adds the option networking.sits, which allows the user to
create named 6-to-4 sit devices.
nixos/dhcpcd: Don't configure sit devices
chntpw:  new expression
qgis: update 1.8.0 -> 2.4.0 and adding sip

Unfortunately adding sip doesn't solve the error-message:

    Couldn't load SIP module.
    Python support will be disabled.
tigervnc: fix xkb configuration for Xvnc

Without those fixes, Xvnc doesn't work at all.
