Also format all files and add a flake.lock for lib
for a folder thats meant to work on other flakes theres never a reason
it should need to refer to itself, only other flakes. So "self" and
"inputs" are better namings for these variables. The userFlake* is
redundant and confusing, when trying to call the functions its hard to
figure out how to use them when there are now two lines of arguments to
figure out.
- [x] refactor lib into separate files, similar to NixOS/nixpkgs/lib.
- [x] refactor ci to automatically generate derivations from flake outputs
- [x] remove cluttered indirection statements throughout the codebase
- [x] refactor hosts to allow for upcoming integration tests
- [x] improve ambiguity in the existing docs
- [x] add [BORS](https://bors.tech) support
- [x] add initial integration test
- [x] write tests documentation
- [x] test lib
- [x] improve version string generation, and do so automatically for pkgs/flake.nix sources
Clean up the codebase as best we can in preparation for #152 and add tests. From now on, all PRs will be merged with BORS.
