lib: reduce internal usage of public require('util')

[joyeecheung]

A few patterns (modulo destructuring):

1. Replace require('util').inherits() usages under lib: Remove util.inherits usage internally? #24395

// Change this
util.inherits(A, B);

// To this
Object.setPrototypeOf(A.prototype, B.prototype);
Object.setPrototypeOf(A, B);

2. Replace require('util').inspect with require('internal/util/inspect').inspect
3. Replace require('util').format with require('internal/util/inspect').format
4. Replace require('util').debuglog with require('internal/util/debuglog').debuglog
5. Replace require('util').types with require('internal/util/types')
6. Replace require('util').deprecate with require('internal/util').deprecate
7. Replace require('util').promisify with require('internal/util').promisify

[micheleriva]

I can work on it 🎉

[joyeecheung]

@micheleriva That's great! If possible please try to refactor each file in single commit and submit them as separate PRs, otherwise the PR is bound to require manual backport.

[SimonSchick]

@joyeecheung Just curious, in many cases util.inherits could be replaced by class ... extends ... instead, is there a reason setPrototypeOf should be used instead?

[micheleriva]

@joyeecheung ok no prob! So I'll close my PR #26552 in flavour of single PRs.

[joyeecheung]

@SimonSchick For public ES5-style classes we have to support instantiation without new so we cannot refactor them to ES6 classes.

[SimonSchick]

I was talking about those that do not support instantiation without new.

Might also be worth mentioning that we dealt with the same issue in sequelize using Proxys https://github.com/sequelize/sequelize/blob/master/lib/utils/classToInvokable.js#L9
I'm not sure what the exact performance penalties are tho.
