  • Move convex_on_norm from specific_functions to topology, use it to golf the proof of convex_on_dist.
  • The old convex_on_norm is now called convex_on_univ_norm. The new convex_on_norm is about convexity on any convex set.
  • Add convex_on_univ_dist and make s : set E an implicit argument in convex_on_dist.

This way APIs about convexity of norm and distance agree.

When I wrote those lemmas I didn't know whether it was more practical to have the univ version or the convex set version.

By the way, do you think we should have a convex_on ℝ s (dist z) version?

I don't know either. I just fixed the inconsistency in API.

IMHO, we should add it whenever we need it.
