This uses libuv's mkdtemp function to provide a way to create a
temporary folder, using a prefix as the path. The prefix is appended
six random characters. The callback function will receive the name
of the folder that was created.
Usage example:
fs.mkdtemp('/tmp/foo-', function(err, folder) {
console.log(folder);
// Prints: /tmp/foo-Tedi42
});
The fs.mkdtempSync version is also provided. Usage example:
console.log(fs.mkdtemp('/tmp/foo-'));
// Prints: tmp/foo-Tedi42
This pull request also includes the relevant documentation changes

In most cases, named functions match the variable or property to which
they are being assigned. That also seems to be the practice in a series
of PRs currently being evaluated that name currently-anonymous
functions.
This change applies that rule to instances in the code base that don't
comply with that practice.
This will be enforceable with a lint rule once we upgrade to ESLint
3.8.0.

When the listener was truthy but NOT a function, fs.watchFile would
throw an error through the EventEmitter. This caused a problem because
it would only be thrown after the listener was started, which left the
listener on.
There should be no backwards compatability issues because the error was
always thrown, just in a different manner.

1. writeFileSync bumps position incorrectly, causing it to drift in
iteration three and onwards.
2. Append mode files will get corrupted in the middle if writeFile or
writeFileSync iterates multiple times, unless running on Linux. position
starts out as null so first write is OK, but then position will refer to
a location inside an existing file, corrupting that data. Linux ignores
position for append mode files so it doesn't happen there.
This commit fixes these two related issues by bumping position correctly
and by always using null as the position argument to write/writeSync for
append mode files.
