Excise use of importJSON
Putting information in external JSON files is IMHO not an improvement
over the idiomatic style of Nix expressions. The use of JSON doesn't
add anything over Nix expressions (in fact it removes expressive
power). And scattering package info over lots of little files makes
packages less readable over having the info in one file.

Remove fetchMD5warn
Deprecation warnings should not be used in Nixpkgs because they spam
innocent "nix-env -qa" users with (in this case) dozens of messages
that they can't do anything about.

This also reverts commit 2ca8833383.

nixos: make it easy to apply kernel patches
This makes it easy to specify kernel patches:

    boot.kernelPatches = [ pkgs.kernelPatches.ubuntu_fan_4_4 ];

To make the `boot.kernelPatches` option possible, this also makes it
easy to extend and/or modify the kernel packages within a linuxPackages
set. For example:

    pkgs.linuxPackages.extend (self: super: {
      kernel = super.kernel.override {
        kernelPatches = super.kernel.kernelPatches ++ [
          pkgs.kernelPatches.ubuntu_fan_4_4
        ];
      };
    });

Closes #15095

22d7c08dc5 lib.trivial: add a new importJSON function
This is meant to be used by packages who often re-generate their inputs.

Producing valid JSON is easier than nix, and also garantees it's purity.

405fda497a lib: document fix and add fix', extends functions
These functions used to live in pkgs/development/haskell-modules/default.nix,
but they are generic, really, and should be easily accessible to everyone.

4a91cfd32b Add a global variable ‘inNixShell’
This is primarily useful in Nix expressions that are also intended to
be used by nix-shell.  It allows saying things like:

  buildInputs = [ ... ] ++ (if inNixShell then [ emacs ] else [ ]);

This should not be used in Nixpkgs (since the question of what
constitutes a useful nix-shell environment is very subjective).

484403bf0e Add a constant ‘nixpkgsVersion’
This makes it a bit easier to find out the current Nixpkgs version,
e.g.

  $ nix-instantiate --eval '<nixpkgs>' -A lib.nixpkgsVersion
  "14.02.35657.66f51a9"
