Adds overloads to accept unseq and par_unseq overloads for the same algorithms.
Unit tests for all three algorithms

Any background context you want to provide?

Since this PR contains #6016 and #6017, we should close those and focus on fixing everything in this PR only. That also means, that all comments added to those PRs equally apply here and should be addressed only here.

@akcube thanks again for your work on this. I have rebased your branch and have done some cleanup to match recent changes. Please have a look and comment. I hope I have not broken anything you had in mind. If all goes well, this can still go into the upcoming v1.9.0 release.
