* Some fetchurl-related refactoring. The `realCurl' attribute is gone, `curl' is the real thing. To prevent an infinite recursion in `fetchurl' (because it depends on curl and building curl needs fetchurl), curl and its dependencies (openssl, zlib, perl) use `fetchurlBoot', which is the fetchurl used by the previous bootstrap phase (e.g. the statically linked version of curl for stdenv-linux). So as a result you can use https:// urls almost everywhere. There's also some hackery to prevent a different curl from being built in every stdenv-linux bootstrap phase (namely the stdenv.fetchurl attribute which allows fetchurl to be overriden everywhere). svn path=/nixpkgs/trunk/; revision=11905
