Motivation for this change

Lemmas eq_bigmax and eq_bigmin in mathcomp_extra.v is wrongly stated in weaker forms
that does not respect their argument P in the returned type.

Things done/to do

This PR fixes the problem by strengthening the statements and amending the proofs.

  • [YES] added corresponding entries in CHANGELOG_UNRELEASED.md
    (do not edit former entries, only append new ones, be careful:
    merge and rebase have a tendency to mess up CHANGELOG_UNRELEASED.md)
  • [NO] added corresponding documentation in the headers
Automatic note to reviewers

Read this Checklist and put a milestone if possible.

add lemma power12_sqrt

fix and strengthen eq_bigmax and eq_bigmin (math-comp#863)

Itv (math-comp#869)

* Add itv.v

Taking inspiration on signed.v, replacing sign by intervals.

* Add interval multiplication

* Add hints to automatically solve _ <= 1 goals

* Test to see if usable as a replacement for prob

* use notation from mathcomp_extra.v

* changelog and rm redundant code

* prefix duplicated identifiers
