Refine README.md and some related files. [skip ci]
Lose the README symlink, it was a bad idea of mine to add it in the
first place as it made the packaging problem space bigger, not smaller.
Remove two CI badges at the top of README.md. One badge was stale
anyway, and the other does not represent the current CI configuration,
which is bigger, changes frequently and fits the web-site much better.
Remove the reference to ITA, it has been down for quite a while, it
looks like it won't re-emerge this time.
