220c33cc31 Fixed two buffer manager performance problems (Markos, Vinayak, thanks for pointing these out!): 
- No longer hold global mutex during page writeback
 
 - Don't reserve 90% of the buffer pool for the free list.  Now the freelist reserves 1% of the buffer pool + 6 pages, and expands if it runs out of space.

5dcf3bd1a4 check_bufferManager should pass now(!!!) bufferManager was crashing with "assert(victim) 
failed" if the application pinned so many pages that the writeback tasks could not write back 
pages in order to maintain the free page list.

 - Instead of crashing, issue warning the first time this happens.

 - Add diagnostic message explaining that all pages have been pinned before crashing 
   due to a failed loadPage() request.

ff0887624c Simplified the page locking conventions. 
Added paranoid calls to assertlock() to page.c

Fixed race in abort():

 - pick CLR LSN

 - release page lock

 - someone else updates page

 - lock page

 - apply undo

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.
