libglusterfs: Implement circular buffer and event history
Implement circular buffer framework, so that it can be used by other components
such as event history management. And event history is implemented which can
be used by xlator to dump some information to a file (such as information of some
structure etc).
Through statedump, history of each xlator can be dumped. An option called history
should be given to the statedump command.
