When data passed to axios is of type FormData we have to let the browser
create the Content-Type header so that the boundaries will get right
etc.
Usage:
```js
var data = new FormData();
data.append('field', 'some string');
data.append('file', someFile);
var opts = {
transformRequest: function(data) { return data; }
};
axios.post('/fileupload', data, opts);
```
In order to push binary data under the form of ArrayBuffer and
its related views (Int8Array, ...) one needs not to stringify
those.
For the XHR adapter there is nothing to do as it natively supports
ArrayBuffer in req.send().
Node's http adapter supports only string or Buffer thus a
transformation to Buffer is required before setting content length
header.
