Proposed changes

This PR adapts the codebase to be less (or more) hackage-specific in several places:

Namespaces are not either "haskell" or "hackage", instead we use the following heuristic:

  if
      | name `Set.member` coreLibraries -> Namespace "haskell"
      | name `Set.member` repositoryPackages -> Namespace repo
      | otherwise -> Namespace "hackage"

This allows us to make reasonable decisions in the following cases:

If package A in repository "alt-repo" depends on package B in "hackage", then A is @alt-repo/A and B is @hackage/B.
If package A in repository "alt-repo" depends on package B in "alt-repo", and B also exists on "hackage", then @alt-repo/A depends on @alt-repo/B.
