Error with RotationFileStream

[gagle]

You need to attach an error handler to the stream that you create in line 930.

You need to do the same as 367.

Steps:

Call the EventEmitter constructor in line 928:

EventEmitter.call (this);

Attach an error listener to the stream in line 930:

var self = this;
this.stream = fs.createWriteStream(this.path,
    {flags: 'a', encoding: 'utf8'});
this.stream.on('error', function (err) {
  self.emit('error', err, options);
});

And finally listen to that error on the main logger instance in line 387:

s.stream.on('error', function (err, s) {
    self.emit('error', err, s);
});

Now, if I create a rotation file with an invalid path (e.g. C:/a, EPERM error) the log.on ("error") callback is executed instead of throwing an exception that quits the process.

Note to self: when doing this, also make sure to test that "cluster + rotating file ... crash" case cannot be reproduced. IOW, we need to also catch and re-emit the error on mvs from that issue.
