Yii2: Remove subtree split (yii2 / yii2-dev)

[schmunk42]

What steps will reproduce the problem?

Have a project with dependency yiisoft/yii2.
Find a tiny bug, fix it and try to push it to your fork.

What is the expected result?

Easy creation of a PR.

What do you get instead?

This branch is 7469 commits ahead, 16992 commits behind yiisoft:master.

I need to use yii2-dev from the very beginning and switching within a project is hard (especially temporary). There should be only one repo for Yii2.

Change could be done in 2.1/3.0

As far as I understand yii team prefers to have all the framework (PHP files, documentation, tests and more) in single repository to be able to have single PR with everything.
But obviously users prefer only PHP files to be installed with composer.
Framework could be split into several repositories: one with source and other(s) with everything else.
But GitHub doesn't allow single PR to multiple repository.

I think this is a matter of file/directory-size in vendor.

156K    build
4.0K    code-of-conduct.md
4.0K    composer.json
84K composer.lock
24K contrib
24K cs
4.0K    Dockerfile
29M docs
6.2M    framework
4.0K    LICENSE.md
4.0K    package.json
4.0K    phpunit.xml.dist
8.0K    README.md
8.0K    ROADMAP.md
4.2M    tests

You'd get additional >30 MB of docs and tests.

with .gitattributes we can exclude files when a zip file is created from the repo, so composer --prefer-source will install everything, --prefer-dist will only install non-dev files.

Let's have .gitattributes

@schmunk42 can you handle it?

I think this is also fixed by having yiisoft/yii-core now.
