* Optionally enable external-helpers in tests
https://github.com/babel/babel/pull/12911 was a breaking change that now requires you to keep `babel-plugin-external-helpers` in your `package.json`. It'll will probably be unnoticeable for most, because another dependency could transitively depend on it, but AMP recently hit it when cleaning up our deps.

* Fix package name
* Lint against CJS globals in modules
* Use `import.meta.url` instead of `__filename` in `src` files

dirname

* limit transform-react-source to run on linux and darwin
* test: escapeRegExp on testcases
* test: add test for babel --filename on windows
* test: double babel-node/cli test timeout
* chore: workaround windows build does not stop
* chore: remove redundant condition
* refactor: rename `nodePlatform` to `os`
* Add support for logs to transform-fixture-test-runner
* Test some warnings
* Use stderr/stdout, and add a validateLogs test option
* Normalize CWD in logs and rename vars
* Silence preset-env tests
* Restore old methods
* Ignore fixture directories that do not contain input or exec
* Fix parser test fixtures structures for some imported esprima tests.
* Warn on test folders that are not empty and do not contain testfiles
* Don't merge test options.
Particularly, I don't want `lodash/merge` to merge my specific plugins
with the general test plugins. It led to odd behavior where I could
enable a loose transform in my specific test, just to have it overridden
by the test fixture's general options.
* Need options
I'm extremely stupid and didn't commit as I go. To anyone reading this
I'm extremely sorry. A lot of these changes are very broad and I plan on
releasing Babel 6.0.0 today live on stage at Ember Camp London so I'm
afraid I couldn't wait. If you're ever in London I'll buy you a beer
(or assorted beverage!) to make up for it, also I'll kiss your feet and
give you a back massage, maybe.
