Summary: Transaction::RollbackToSavePoint() will now release any locks that were taken since the previous SavePoint. To do this cleanly, I moved tracked_keys_ management into TransactionBase. Test Plan: New Transaction test. Reviewers: igor, rven, sdong Reviewed By: sdong Subscribers: dhruba, spetrunia, leveldb Differential Revision: https://reviews.facebook.net/D46761
