eb8b57378a laying the groundwork for snowshoveling; as of this commit, pointers and null padding happens in an order that should let us query incomplete tree components. We should only need short page latches at this point (so that we do not look at partially written keys/values)

ed9d4fc377 Encapsulate allocator state inside logtree. Remove redundant information from merger_args. Rewrite merge threads. This seems to fix the double free issues, and gets rid of disk space leaks. It's probably leaking ram, and does not keep the logstore headers up to date.

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.
