7c2397340c Fixed a bunch of iterator bugs and racy merges. Added drop_database utility. 
Bugfixes:
 - Atomically deallocate regions and update the logstore object
 - Proactively invalidate iterators after each merge (before, it would simply set a not-valid bit.  This doesn't work because iterators hold page pins, which breaks force-writes)
 - Clarify semantics of opening iterators mid-stream:  All calls now return iterators that return first key >= the requested one.  revalidate() needs the key > the requested one, so it calls peek(), then (if necessary) getnext().
 - Add asserts to check that the header is latched at update, and that tuples returned by iterators are strictly monotonically increasing'
 - Improve error handling in network.h  We still get (and terminate on) SIGPIPE.

Refactoring:
 - Add dispatch function to network.h.

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.

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.
