From: Cyril Cohen

Subject: Improvements

- deprecating `fintype.arg_(min|max)P`
- removing dangling comments connecting min max and meet join
- better compatibility module
- removing broken notations with `\min` and `\max` (no neutral available)
- fixing `incompare` and `incomparel` in order.v
- adding missing elimination lemmas (`(comparable_)?(max|min)E[lg][et]`)
- adding missing `(comparable|real)_arg(min|max)P`
- CHANGELOG update
