[9.x backport] assert & util PRs #19230

BridgeAR · 2018-03-08T15:28:00Z

This is a backport of all assert PRs to 9.x that are requested at the moment (as far as I know) plus one util PR. I felt this is much easier because as soon as a couple conflicts were resolved most other commits were easy to backport on top as well.

#17576
#17002
#17582
#17703
#17585
#17584
#17903
#18029 (@bnoordhuis this landed cleanly after my former commits)
#17615
#18595
#18248
#18611

I also included 8e6e1c9 even though it landed in a semver-major PR. But that PR on it's own is not semver-major.

Requireing the strict version will allow to use `assert.equal`, `assert.deepEqual` and there negated counterparts to be used with strict comparison instead of using e.g. `assert.strictEqual`. The API is identical to the regular assert export and only differs in the way that all functions use strict compairson.

The current default formatting is not ideal and this improves the situation by formatting the output more intuitiv. 1) All object keys are now indented by 2 characters instead of sometimes 2 and sometimes 3 characters. 2) Each object key will now use an individual line instead of sharing a line potentially with multiple object keys. 3) Long strings will now be split into multiple lines in case they exceed the "lineBreak" option length (including the current indentation). 4) Opening braces are now directly behind a object property instead of using a new line. 5) Switch inspect "base" order. In case the compact option is set to `false`, inspect will now print "[Function: foo] {\n property: 'data'\n}" instead of "{ [Function: foo]\n property: 'data'\n}".
