Removed old VoltDB code...
Fixed 'eecheck-build' so that it only builds the tests (and not also run them). Fixed EE build scripts so that the EE debug log levels are propagated to the tests as well.
Minor refactoring. Fixed client startup time stopwatch reporting
This is an important one. We can now undo a range of tokens in the EE instead of just blindly rolling back anything that comes after given token. I'm not going to hook this up just yet, but it's a start for allowing us to do more interesting things...
Another stab at refactoring PartitionExecutor.finishDistributedTransaction(). I've decided that we're just going to use the coarse-grained undos and rollback anything that comes *after* the first txn that we have to abort in a specexec batch. This is good enough for now...
