cb614dff1b fix nasty bug where diskTreeComponent (perhaps) drops tuples. With the recently added paranoid checks, this fix should do nothing worse than trigger assertion failures (as opposed to silently losing data...)

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.
