6d17442380 Major refactoring: 
- Changed operations to take only two arguments
     - No more hacks regarding log argument sizes

     - Set pageid = INVALID_PAGE if you want a logical operation

  - Ported operation implementations to new api; exposed + fixed a number of concurrency bugs

  - More fixes to prepare

  - Fixed to nested top actions

  - More coherent operations api / recovery implmentation

  - TnaiveHash* and Tinstant* are (and were already) broken, and are set for removal

  - Removed some instances of fail_unless

  - Fixed design flaws in blob implementation.

  - New naming convention for operation callback functions.
