zfs-0.6.2 and spl-0.6.2

Enable parallelBuilding, too.
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.
Add lens-datetime haskell library
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.

Add lens-datetime haskell library
haskell-distributed-process: drop broken package

distributed-process won't compile, and upstream doesn't accept bug reports
without some elaborate registration procedure.
qemu: Revert to 1.5.2

1.6.0 breaks many VM builds because it gives incorrect RTC values to
the guest.  See

Add noHaddock flag to modular-artihmetic

Building of haddock for packages with UTF-8 source is already
fixed in the stdenv-updates branch.  This fixes modular-arithmetic
until that branch is merged.  Will send another pull request to
add back haddock for that branch.
libav: major update and refactoring (close #839)

Also leaving 0_8 branch, as it's compatible with older ffmpeg versions.
I'm planning that all expressions will be able to switch easily
between ffmpeg and libav (whatever default we choose, but I prefer libav).

Edited (twice) according to notes on the reverted b003138.
Make generated node expression overridable in nodePackages.
