Upcall: New xlator to store various states and send cbk events
Framework on the server-side, to handle certain state of the files
accessed and send notifications to the clients connected.
A generic and extensible framework, used to maintain states in
the glusterfsd process for each of the files accessed
(including the clients info doing the fops) and send
notifications to the respective glusterfs clients incase of
any change in that state.
This patch handles "Inode Update/Invalidation" upcall event.
