ati-drivers: fix download
pythonPackages.matplotlib: Update to use buildPythonPackage

Matplotlib is currently using hacked together build / install phases
which mimick this functionality of buildPythonPackage. This patch
changes the expression to remove the duplicated build scripting.
network-manager-applet: re-do schema generation

fixes #1355. partial revert of f4d4e12c (introduced by #1313).

meta.priority is set to 6 (lower priority than standard) to resolve the
conflict of an exported gschemas.compiled for evince as for nm-applet.
this linked file is NOT consulted, as both binaries are wrapped to look
for their schemas in their nix store path first.

a better fix would avoid already avoid linking those gschemas.compiled
files into the environment.
ifenslave: Add new package
network-interfaces: Add the ability to create bond devices

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).
fftw: minor update and major refactoring

- Unify the "single" and "float" variants, which are the same thing.
- Enable threads and openmp wrapper by default (they are very small).
- Don't use sse on i686, as I'm quite sure we have no warrant for that.
  Cf. http://en.wikipedia.org/wiki/Pentium_Pro
- Disable static libs (big, no indication we need them).
- I tested most builds using fftw (they build OK).
