This allows to plug in concurrency monads like Lwt, Async or Dune's Fiber into the solver and have the callbacks return the concurrency monad.

This isn't needed with OCaml 5 - in fact, the ICFP Eio tutorial used the example of performing Lwt operations in the solver's callback, without having to modify the solver at all. It seems a shame to add all this just for older systems. Dune has a way to build on newer compilers but run with older ones - perhaps that could be used instead? |

Currently work in progress, needs support code in 0install-solver as well.
