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.

Currently, when a process times out, it is terminated by sending it the
SIGTERM signal. Sending SIGBART instead allows the operating system to
generate a core file that can be investigated later using post-mortem
debuggers such as llnode or mdb_v8.

This can be very useful when investigating flaky tests that time out,
since in that case the failure is difficult to reproduce, and being able
to look at a core file makes a big difference.

With these changes, passing the --abort-on-timeout command line option
to tools/test.py now sends SIGABRT to processes timing out on all
platforms but Windows.

const URL = url.URL;

const str = url.format(myURL, {fragment: false, search: false});

When emitting a 'connection' event on a httpServer, the function
connectionListener is called. Then, a new parser is created, and
'consume' method is called on the socket's externalStream. However,
if this stream was already consumed and unconsumed, the process
crashes with a cpp assert from the 'Consume' method in stream_base.h.
This commit makes sure that no SIGABRT will be raised and the process
will stay alive (after emitting the socket).
