(zilch nixpkgs): add dataflow tracking support
...
Dataflow tracking runs the installPhase of a derivation, and then
does its best to track build input -> store path output pathways.
This allows for substituting the installPhase of a derivation as much
as possible with relatively quick store path logic, allowing for cross-
project build input tracking.

(zilch magic): purposely dangle self-references in IA->CA handling
...
This is to workaround an issue I don't know how to fix right now.
In effect: Some of the Nix code contains the placeholder for $out,
which then gets translated to $out for that store path. Converting that
fails, for obvious reasons. However, rewriting those to self-references
is more complicated than I want to get into right now, and as the
behavior of self-references is vaguely broken (and this only affects
one test and a comment), I'm going to take the easy way out and make
it generate a dangling reference.

(zilch magic): Replace daemon-handled CA derivations with Zilch
...
Lix is deprecating CA derivations, and it's not too difficult to have
this be handled entirely by Zilch. This also improves stability and
future handling of the feature, as Zilch does not depend on how the
daemon handles CA derivations. Though right now, the behavior of
CA derivations is identical to that of the experimental feature, at
this time.
Building CA derivations requires a small scheduler to bypass the Nix
behavior. Each CA derivation is recorded, and then all derivations that
have no CA dependencies get built. These are used to resolve the
realisations for the derivations that depend upon them, and the the
cycle continues.
