2024-05-07libutil: de-callback-ify computeClosureeldritch horrors
only two users of this function exist. only one used it in a way that even bears resemblance to asynchronicity, and even that one didn't do it right. fully async and parallel computation would have only worked if any getEdgesAsync never calls the continuation it receives itself, only from more derived callbacks running on other threads. calling it directly would cause the decoupling promise to be awaited immediately *on the original thread*, completely negating all nice async effects.

`///@file` makes them show up in the internal API dos. A tiny few were missing `#pragma once`.
2021-05-19Extract a generic `computeClosure` functionregnat
Move the `closure` logic of `computeFSClosure` to its own (templated) function. This doesn’t bring much by itself (except for the ability to properly test the “closure” functionality independently from the rest), but it allows reusing it (in particular for the realisations which will require a very similar closure computation)
