Packages: Move packages repository into Gutenberg

[omarreiss]

Description

Adds https://github.com/WordPress/packages/ including all commit history to Gutenberg.

Once this is merged, we need to start moving over issues and PR's from the old repo to Gutenberg as well.

How has this been tested?

I have only tested the script for creating symlinks. Hoping @gziolo could take over from here. 😄

Types of changes

I ran git subtree add --prefix temp-packages https://github.com/WordPress/packages.git master to preserve the commit history. Then I moved the files over to the right directories, synchronized the config files and scripts and removed what was no longer needed.

Checklist:

• My code is tested.
• My code follows the WordPress code style.
• My code follows the accessibility standards.
• My code has proper inline documentation.

We probably don't need this line anymore.

@aduth @youknowriad - do we want to run our tests against src, build or build-module? What if we provide src locally and build-module on Travis?

[youknowriad]

I think we should only run src for both.

[gziolo]

We are all good then 👍

Unit tests fail because of the following issue: jestjs/jest#4407:

Using .toThrowErrorMatchingSnapshot() on code that prints error using ansi codes (i.e. using chalk) produces different snapshots if run locally or on CI.

There is a workaround proposed:

https://github.com/joaogranado/jest-serializer-ansi

However, it still fails for us with a really interesting output:

jest-console › console.error › toHaveErroredWith works when not called
[1]
[1] expect(value).toMatchSnapshot()
[1]
[1] Received value does not match stored snapshot 1.
[1]
[1] Compared values have no visual difference.

In particular Compared values have no visual difference. is puzzling.
