2a1157602a Rewrite merge thread synchronization code, update status messages, implement preliminary (and ineffective) admission control, and force write merged data every megabyte (so that prograess can be tracked by admission control. Also, refactor quite a few things.

6f968fd825 Rewrote datapage region allocator. It no longer scribbles all over itself during merges, but it tries to double free datapage regions. Committing with datapage region reclamation disabled for now.

f2df52319d Rewrote datapage. There is a feature regression: datapages do not try to extend themselves when they encounter a large record, and there is a 1:1 relationship between datapages and regions. A later revision will change the interface with the region allocator in order to address this. This will establish a 1 region -> n datapage relationship. There used to be an n:m mapping.

940a6da6fe Reworked memory allocation and network protocol. This gargantuan commit also reduces the default size of C0, and removes quite a bit of redundant logic and error handling. 
The tests now pass, except that check_merge never terminates (it takes too long) and check_mergelarge still is not passing.

For better luck running this version of the code, turn off stasis' concurrent buffer manager.  We're doing something bad that leads to deadlocks with the concurrent buffer 
manager.  Another (the same?) bug less-frequently leads to page corruption with the old stasis buffer manager.
