The RocksDB ticker and histogram statistics were out of sync between the C++ and Java code, with a number of newer stats missing in TickerType.java and HistogramType.java. Also, there were gaps in numbering in portal.h, which could soon become an issue due to the number of tickers and the fact that we're limited to 1 byte in Java. This PR adds the missing stats, and re-numbers all of them. It also moves some stats around to try to group related stats together. Since this will go into a major release, compatibility shouldn't be an issue.
This should be automated at some point, since the current process is somewhat error prone.
