1. full functional WAL for GiST

2. improve vacuum for gist
   - use FSM
   - full vacuum:
      - reforms parent tuple if it's needed
        ( tuples was deleted on child page or parent tuple remains invalid
          after crash recovery )
      - truncate index file if possible
3. fixes bugs and mistakes
