5ffd1110e9 Added concept of "transaction fingerprints" 
The region allocator marks freed regions "Condemned" before actually freeing them.  Condemned regions are associated 
with a transaction; before they can be reused / coalesced the transaction that condemned them must complete.

The region allocator used "TisActiveTransaction(xid)" to determine whether a given transaction had completed.  The 
problem is that Stasis now reuses transaction id's, and condemned regions were never reclaimed in practice.  A transaction
fingerprint is a unique identifier (currently transaction id, rec_lsn) that can be used to distinguish transactions that
did not execute concurrently.

I considered an alternative design based upon end-of-transaction actions.  This would have worked as well, but would 
have been a more invasive change.

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.
