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.
