zfs-0.6.2 and spl-0.6.2

Enable parallelBuilding, too.
v8: build binaries for unix platforms
node-packages: add ungit and update packages
KDE: we don't really support anything but Linux right now, so no reason to have all those evaluation
errors.
getmail: 4.20.0 -> 4.42.0
add ungit to node-packages.json
bbswitch: upgrade to 0.7

Upstream insists on using private qt headers.
We do not want nixpkgs' qt to export those.
So I provided a small hack to take them directly from qt's source tarball.
I made sure everything uses the normal system qt and headers, except for the
1 .so file (qt_hack) that needs these private headers.

Because of this, there is barely any increate in size or buildtime.
calibre: fix for chroot builds (probably)
samba: install libnss_{wins,winbind}.so

This is the first step to get WINS/NetBIOS name lookup with nsswitch.
vte: patch for alt key (close #858)

Edit (vcunat): bump to latest version supporting gtk2.
eagle: bump version 6.4.0 -> 6.5.0

And name the desktop file "eagle.desktop", not "Eagle.desktop". The user
facing application name is still "Eagle"; it has nothing to do with the
name of the desktop file.

pypi2nix: updated
Plone: fixed Pillow
calibre: really fix building on master

It turns out I hardcoded the output path that qt's tarball extracts.
But that path is versioned (4.8.5 for example).
As I've already merged x-updates on my own system, my qt version was
different (4.8.4 vs 4.8.5). Made the path-guessing more flexible, so
now it should work with any 4.8.*

Elixir: Fix impurity with Erlang.

The bash scripts of elixir contain some references to `erl'. This
patch wraps the scripts and extends PATH so `erl' is available.
