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
and tests.
