Updates the fs module APIs to allow 'file://' URL objects
to be passed as the path.
For example:
```js
const URL = require('url').URL;
const myURL = new URL('file:///C:/path/to/file');
fs.readFile(myURL, (err, data) => {});
```
On Windows, file: URLs with a hostname convert to UNC paths,
while file: URLs with drive letters convert to local absolute
paths:
```
file://hostname/a/b/c => \\hostname\a\b\c
file:///c:/a/b/c => c:\a\b\c
```
On all other platforms, file: URLs with a hostname are unsupported
and will result in a throw:
```
file://hostname/a/b/c => throw!
file:///a/b/c => /a/b/c
```
The documentation for the fs API is intentionally not updated in
this commit because the URL API is still considered experimental
and is not officially documented *at this time*
Note that file: URLs are *required* by spec to always be absolute
paths from the file system root.
This is a semver-major commit because it changes error handling
on the fs APIs.
