top-level: Normalize stdenv booting Introduce new abstraction, `stdenv/booter.nix` for composing bootstraping stages, and use it everywhere for consistency. See that file for more doc. Stdenvs besides Linux and Darwin are completely refactored to utilize this. Those two, due to their size and complexity, are minimally edited for easier reviewing. No hashes should be changed.

# This file chooses a sane default stdenv given the system, platform, etc.
* Use a 2-stage bootstrap for creating the standard build environment (stdenv) on Linux. The previous 1-stage bootstrap was insufficient, because the tools in stdenv where built by native tools. For instance, the Nix bash had a reference to /lib/libncurses. This doesn't happen with a 2-stage bootstrap, since the bash built in stage 2 will be built with the gcc built in stage 1, which doesn't search in the "standard" locations. Motto: "Disparaging the boot is a bootable offense." svn path=/nixpkgs/trunk/; revision=809

top-level: Close over fewer arguments for stdenv stages This makes the flow of data easier to understand. There's little downside because the args in question are already inspected by the stdenvs. cross-compiling in particular is simpler because we don't need to worry about overriding the config closed over by `allPackages`.

# Args to pass on to the pkgset builder, too
Add overlays mechanism to Nixpkgs. This patch add a new argument to Nixpkgs default expression named "overlays". By default, the value of the argument is either taken from the environment variable `NIXPKGS_OVERLAYS`, or from the directory `~/.nixpkgs/overlays/`. If the environment variable does not name a valid directory then this mechanism would fallback on the home directory. If the home directory does not exists it will fallback on an empty list of overlays. The overlays directory should contain the list of extra Nixpkgs stages which would be used to extend the content of Nixpkgs, with additional set of packages. The overlays, i-e directory, files, symbolic links are used in alphabetical order. The simplest overlay which extends Nixpkgs with nothing looks like: ```nix self: super: { } ``` More refined overlays can use `super` as the basis for building new packages, and `self` as a way to query the final result of the fix-point. An example of overlay which extends Nixpkgs with a small set of packages can be found at: https://github.com/nbp/nixpkgs-mozilla/blob/nixpkgs-overlay/moz-overlay.nix To use this file, checkout the repository and add a symbolic link to the `moz-overlay.nix` file in `~/.nixpkgs/overlays` directory.

top-level: turn the screw - Non-cross stdenvs are honest and assert that `crossSystem` is null - `crossSystem` is a mandatory argument to top-level/stage.nix, just like `system` and `platform` - Broken default arguments on stdenvs for testing are gone. - All stdenvs (but little-used stdenvNix) take the same arguments for easy testing.
