Remove utility to reduce package size

[jimmywarting]

This two can easily be replaced with Object.assign({}, ...) or with spread { ... }

urllib/lib/httpclient.js

Line 40 in f2a42d1

args = utility.assign({}, [ this.defaultArgs, args ]);

urllib/lib/httpclient.js

Line 51 in f2a42d1

args = utility.assign({}, [ this.defaultArgs, args ]);

Here you can use Object.keys()

urllib/lib/urllib.js

Line 309 in 04734a1

var names = utility.getOwnEnumerables(args.headers, true);
