debug/trace: save the recent fops received in the event-history
* Make use of event-history in debug/trace xlator to dump the recent fops, when statedump is given. trace xlator saves the fop it received along with the time in the event-history and upon statedump signal, dumps its history. The size of the event-history can be given as a xlator option. * Make changes in trace to take logging into log-file or logging to history as an option. By default both are off.
