for clarity's sake, expose which function uses final and prev, so that
people can have a clearer understanding how they relate to each other
in terms of dependencies.
also a simple `{ lib = final; }` probably does not warrant a complete
callLibs obscurization.
231: Move flake implementation logic to lib r=nrdxp a=Pacman99
This is a simpler version of #218 that moves flake logic to lib and adds a module to evaluate devos. This DOES NOT support out of tree usage, so if you were following any of the previous PR's, the doc sections/examples to use devos as a library will not work. There is work to make a cleaner api and only then will out of tree support work. Until then, this is still useful to simplify devos and clean up a lot of the implementation logic.

224: Allow for directories in module-list r=nrdxp a=Pacman99
fixes#221
building on #222 this PR improves the lib functions pathsToImportedAttrs and pathsIn. First to add support for directories. This does not support actually passing a file in a directory, so `./matrix/default.nix` won't work but `./matrix` will - I should probably document this somewhere.
Also I moved the filtering for nix files to `pathsIn`, since its only necessary for auto-import. We can assume that users would pass proper files in `module-list.nix`.

217: lib/mkPkgs: don't import external files and get inputs as argument r=nrdxp a=Pacman99
Changes mkPkgs to take extern, overrides, and pkgs as an argument. This improves their ability to be used as lib functions.

220: Drop flattenTreeSystem and use custom function for filtering packages r=nrdxp a=Pacman99
I don't think we should flatten the system because if a user doesn't make a package a derivation in pkgs/default.nix we should trust that there is a reason for doing so. So instead this drops the flattenTreeSystem reference(and switches to flake-utils master branch) and replaces its usage with a custom function `filterPackages`. This function filter all packages that match three conditions;
- is a derivation
- not broken
- system is supported
In that order as to not cause errors when trying to reference non-derivation meta attributes.
And then also just dump *all* packages into legacy packages, so everything else is still accessible. I was considering removing the packages that are already in the packages output in legacyPackages, but I don't think its necessary since nix looks to the packages output first.
