* Distinguish request and response data types

* Fix Axios headers type

`axios.headers` is not of the same type as `request.headers`, so a new type
`AxiosDefaults` was introduced

* Replace grunt-ts with dtslint

This asserts that the type definitions are valid in the specified TypeScript
version and above. This is the same tool that is used by DefinitelyTyped.

* Remove grunt-ts

* Restore typescript dependency

- Everything still works as expected.
  - Remove bundlesize
    - It still uses libtorb which is deprecated and broken on Win and
      requires a full suite of build tools on Mac. Keeping it in the
      package makes it difficult for anyone filing issues to run tests.
    - See: #3396
  - Update grunt and it's plugins
  - Update karma to v4...so much faster!
    - Changed the karma config. Better changes: #3394
  - Update Webpack
    - Uses terser over uglify
  - Update eslint
    - Caused an error in util.js from the `global` directive so the
      directive is removed (it was not needed).
  - Update typescript
    - The old version of tsc didn't know about new features in
      @types/node (like `asserts value`).

* Compatible with follow-redirect aborts the request

* Use the error code

* Remove dependency on is-buffer from package.json

* Revert "Update Webpack + deps, remove now unnecessary polyfills (#2410)"

This reverts commit 189b34c4.

* Fix build (#2496)

* Change syntax to see if build passes

* Test commit

* Test with node 10

* Test adding all browsers in travis

* remove other browsers when running on travis

* Update deps

 * handles webpack 1 -> 4 migration

* remove promise helpers from dev files

assume `Promise` is available, or polyfilled by
the consumer

* Remove isArray util. `isArray` has good coverage, even
   in IE9. So lets remove the custom polyfill.

 https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/isArray

also resolves a few lint issues

* Remove trim util

String.protoype.trim has good coverage (including IE9)

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/Trim

Also, the http adapter already uses the native method.
