Hamish Mackenzie 612e983daa Move all of haskell.nix into haskell-nix (#289) ...

Currently the haskell.nix overlays replace `haskell` and
`haskellPackages` in the root of pkgs with versions that have just a
fraction of what nixpkgs provides.
Although `haskell-nix.haskellPackages` could be used to provide a much
more complete set there are subtle differences that are likely to cause
issues (and nixpkgs has patches for many haskell packages).

To make it possible for haskell.nix and nixpkgs haskell to coexist,
we need to move the remaining parts of haskell.nix outside of the
`haskell-nix` attribute into `haskell-nix`.

```
  ghc                        -> haskell-nix.ghc
  cabal-install              -> haskell-nix.cabal-install
  haskell.compiler           -> haskell-nix.compiler
  haskell.packages           -> haskell-nix.packages
  bootstrap.haskell.compiler -> haskell-nix.bootstrap.compiler
  bootstrap.haskell.packages -> haskell-nix.bootstrap.packages
```

The following `haskellPackages` have been removed and instead the
nixpkgs versions will now be in `haskellPackages`.  User code should
be updated if the nixpkgs versions are not desired:

```
  haskellPackages.hoogle
    -> haskell-nix.haskellPackages.hoogle.components.exes.hoogle
  haskellPackages.happy
    -> haskell-nix.haskellPackages.happy.components.exes.happy
  haskellPackages.alex
    -> haskell-nix.haskellPackages.alex.components.exes.alex;
```

Guard code has been added to overlays/defaults.nix to prevent us
inadvertently depending on the nixpkgs `haskell` or `haskellPackages`
inside the haskell.nix code base.
