External hackages (#535)
* Add support for external Hackage repositories Currently haskell.nix is not able to build Cabal projects that depend on packages from private Hackage repositories, as it make only main Hackage available to cabal. This is unfortunate. This commit adds this functionality, by allowing the user to pass `extra-hackages` and `extra-hackage-tarballs` to `mkPkgSet` and `callCabalToNix` respectively, to add as much extra repositories as needed. This repositories are first made available to Cabal when calling `v2-configure`, resulting in correct plans. Later they are combined with global Hackage when building dependencies of the local packages. * Use cabal.project.freeze if available Currently callCabalProjectToNix does not copy `cabal.project.freeze` from source directory, leading to different build plans when building components with nix and when building project with `cabal new-build` inside `nix-shell`. This behavior is undesired, so this commits fixes it. * Add tests for extra-hackages functionality Co-authored-by: Moritz Angermann <moritz.angermann@gmail.com>

# Tests for extra Hackage functionality
|
||||
|
||||
This directory contains two packages, `external-package-demo` and `external-package-user`, the
|
||||
second one depends on the first one. Both packages were created with `cabal init`.
|
||||
|
||||
`external-package-demo` was uploaded to local Hackage at `localhost` and `01-index.tar.gz` from that
|
||||
Hackage was downloaded to this directory. Then the index file was processed with `hackage-to-nix`,
|
||||
the result is in `hackage/` directory.
|
||||
|
||||
The tests check that `cabalProject'` is able to construct plan with dependencies from extra Hackage
|
||||
and then build the package itself.
