libxlator: Change marker xattr handling interface
- Changed the implementation of marker xattr handling to take just a function which populates important data that is different from default 'gauge' values and subvolumes where the call needs to be wound. - Removed duplicate code I found while reading the code and moved it to cluster_marker_unwind. Removed unused structure members. - Changed dht/afr/stripe implementations to follow the new implementation - Implemented marker xattr handling for ec.
