This separates the scheduling logic (including simple hook pathway) from the local-store needing code. This should be the final split for now. I'm reasonably happy with how it's turning out, even before I'm done moving code into `local-derivation-goal`. Benefits: 1. This will help "witness" that the hook case is indeed a lot simpler, and also compensate for the increased complexity that comes from content-addressed derivation outputs. 2. It also moves us ever so slightly towards a world where we could use off-the-shelf storage or sandboxing, since `local-derivation-goal` would be gutted in those cases, but `derivation-goal` should remain nearly the same. The new `#if 0` in the new files will be deleted in the following commit. I keep it here so if it turns out more stuff can be moved over, it's easy to do so in a way that preserves ordering --- and thus prevents conflicts. N.B. ```sh git diff HEAD^^ --color-moved --find-copies-harder --patience --stat ``` makes nicer output.
