* Reverted r6713, r6711, r4623, r3660, r2237. There rewrote fetchurl

URLs to http://nix.cs.uu.nl/dist/tarballs.  With content-addressable
  mirror support (r9190, NIXPKGS-70) this is no longer necessary:
  fetchurl will try to download from that location automatically.  So
  we can keep the original URLs.
