We split configuration-hackage2nix.yaml into multiple files. We bump cabal2nix-unstable to get support for multiple config files in hackage2nix. * The file main.yaml is only supposed to be edited by humans. * The file stackage.yaml is only supposed to be updated by the update-stackage.sh * The file broken.yaml can be edited by humans, but probably future helpers will want to insert broken packages into this file based on hydra reports. * The file transitive-broken.yaml is newly introduced to be generated by regenerate-transitive-broken-packages.sh regenerate-transitive-broken-packages.sh makes a nix query (in transitive-broken-packages.nix) which evaluates all haskellPackages once with and once without "allowBroken" this way it get's a list of packages which are broken by some transitive dependency, but does not disable packages which have eval errors not caused by a broken package.
