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.
