This PR introduces a general notion of periodicity. It also includes proofs of the "usual" properties of periodic (and antiperiodic) functions.


As suggested by @fpvandoorn in #7107.

Once everything is sorted here, I plan to open PRs with applications of these proofs (e.g. the trig functions) and more facts about periodic functions (e.g. a continuous periodic function is bounded, integral/derivative of a periodic function).

…trigonometric functions (#7841)

I use the periodicity API that I added in #7572 to write lemmas about sine (real and complex), cosine (real and complex), tangent (real and complex), and the  exponential function (complex only).
