Issue Description:

The following 4 functions of URL are marked as mutating, yet they do not actually mutate the URL.

public mutating func setResourceValues(_ values: URLResourceValues) throws
public mutating func setTemporaryResourceValue(_ value : AnyObject, forKey key: URLResourceKey)
public mutating func removeAllCachedResourceValues()
public mutating func removeCachedResourceValue(forKey key: URLResourceKey)

Resource values are not part of the URL, rather they are a part of the file which URL points to. Therefore manipulating resource values shouldn't be mutating.
