Just for the hell of it (but when I should actually be writing my dissertation), I removed a bunch of unused VoltDB files. Eventually we'll trim most of this stuff out that we don't need anymore...
Removed DependencyPair. Everything should be using DependencySet.
Ok I really need to stop now... I've removed the unused VoltDB dtxn code, failure handling code, some random test code that's not being used anymore, and some message types... I'll stop now, I swear...
I knew I couldn't keep my promise... removed the old VoltDB message objects. H-Store uses protocol buffers instead... they're not the most optimal thing (since we have to copy ByteBuffers into ByteStrings), but it's good enough for now...
Well look at this... one more commit. It looks like I was able to delete the rest of VoltDB's internal messages after all... Ok that's it, I'm done
Added back the automatic heartbeat stuff to the HStoreCoordinator. We don't do anything with the updates now, but we may in the future...
Merge branch 'master' into anticache
Minor refactoring to PlanNodeUtil
