url.resolveObject(url.parse(x), y) == url.parse(url.resolve(x, y)); 

added a .path property = .pathname + .search for use with http.request

And tests to verify everything.
With the tests, I changed over to deepEqual, and I would note the comment on the test
['.//g', 'f:/a', 'f://g'], which I think is a fundamental problem

This supersedes pull 1596
