This adds a new util package with some useful functionality which could
be implemented as pure mcl, but instead we add it here as a good place
to help with code reuse.
With the release of Fedora 41, I was getting lots of mirror errors.
Hopefully this helps make it more robust. It was failing repeatedly
while trying to download packages, and I kept having to restart things,
but once I added this option things worked. Hopefully they're related.
Here's a good first way to implement handoff. What's particularly
elegant about handoff here, is that this is the first form of it I know,
where handoff happens between a provisioning tool and a configuration
management tool and those are the same tool! As a result, this can allow
for some really elegant integration, and the end-user never has to deal
with the combinatorial explosion of the N * M scenario of gluing each
provisioning tool to each different configuration management tool.
We'll have other forms of handoff in the future, but this simple
approach is useful already.
This makes the current deploy available. This is likely not useful when
this is used from the embedded provisioner cli tool, since it would
contain cli functions that won't run, but it is useful when it's used as
a library.
This gives us a function to return a created vardir folder. It is not
locally namespaced, and a future function will have to namespace one to
each scope.
We need better overview of all the PXE/netboot stuff, probably we should
read a spec, but until an expert comes along, we'll have to proceed
incrementally.
This adds a modern type unification algorithm, which drastically
improves performance, particularly for bigger programs.
This required a change to the AST to add TypeCheck methods (for Stmt)
and Infer/Check methods (for Expr). This also changed how the functions
express their invariants, and as a result this was changed as well.
This greatly improves the way we express these invariants, and as a
result it makes adding new polymorphic functions significantly easier.
This also makes error output for the user a lot better in pretty much
all scenarios.
The one downside of this patch is that a good chunk of it is merged in
this giant single commit since it was hard to do it step-wise. That's
not the end of the world.
This couldn't be done without the guidance of Sam who helped me in
explaining, debugging, and writing all the sneaky algorithmic parts and
much more. Thanks again Sam!

Plumb through the standard context.Context so that a function can be
cancelled if someone requests this. It makes it less awkward to write
simple functions that might depend on io or network access.
This removes the exclusive from the res names and edge names. We now
require that the names should be lists of strings, however they can
still be single strings if that can be determined statically.
Programmers should explicitly wrap their variables in a string by
interpolation to force this, or in square brackets to force a list. The
former is generally preferable because it generates a small function
graph since it doesn't need to build a list.
