Unretiring pgRouting

Hi all,

I would like to unretire pgRouting. pgRouting was orphaned and retired 
because of a problem in the packet requirements specification at the 
time [1].

Since I use this PostgreSQL extension at work, I wanted to reintroduce 
it in Fedora instead of using docker containers or custom packages for 
development.

I have just filed a re-review request on bugzilla [2]. Reviewers are 
welcome :D.
