"seperate" -> "separate".

Missing comma in first example of this tutorial.

ESDoc failed to build because there were references to the deleted
changelog.md file

Closes #6550

Small change the docs in order to fix an incorrect ES6 arrow function.

Should reference products instead of projects in "Creating elements of a "HasMany" or "BelongsToMany" association" section.

* drain doesnt take a callback, it returns a promise instead

* update changelog

* add test

* add class method "increment"

Basically moving code from instance method `increment` to class method `increment`.

close #6359

* fix tests. change: require options.where

Column comments are not a currently supported feature and should not possess documentation references.

Documentation should be readded when the feature is supported once again; until then, the documentation is inaccurate and misleading to users.

```
User.findAll({
    where: {
        '$Instruments.name$': { $iLike: '%ooth%' }
    }
    include: [{
        model: Tool,
        as: 'Instruments'
    }]
})
```

Did not have a comma between the key `include` and the key `where`. People who would copy/paste this code would get an error.

A comma was added.

* Create TOC for class methods, cleanup titles

Finding content within the doc is a pain, so adding a link to their sections in the markdown should help. Also styled the class methods in the headings on the page.

* Update models-usage.md

* [ci skip] Docs: Added v3 to v4 migration guide

* Some corrections

* deprecated -> removed

* Extend ES6 class docs

* Fix indentation

* changelog url

* fix: pooling fails to handle disconnection

* fix: memory outage due to leak

* sinon dont like delay, use setTimeout

* review: code refactor

* review: code refactor, get rid of _acquire

* refactor: use race with timeout

* Add relative and full path support for sqlite

If the dialect is 'sqlite', then we parse host+pathname as a file path.
sqlite documentation suggests that this is the right way to parse them:
https://sqlite.org/c3ref/open.html#urifilenameexamples

If the "storage" option is provided, then that wil take precedence.

Examples:
sqlite:subfolder/dbname.db => subfolder/dbname.db
sqlite:/home/abs/dbname.db => /home/abs/dbname.db

* Add dialect check for the unit tests

* Update docs and changelog

* Amplify docs for "import" instruction
