This causes the following to not compile anymore
\#include <utility>
\#include <vector>
using namespace std::rel_ops;
int main() {
std::vector<int> xs;
return xs.rbegin() != xs.rend();
}

This is to simplify the backup process so that whenever there is an old epoch
in the log system, we always know its begin version and can backup from that
version if no progress is known for that old epoch.
If there are unfinished ranges in the old epochs, the new master will recruit
backup workers responsible for finishing these ranges. These workers remains in
the cluster until the next epoch, when it will remove itself.
This enables backup workers to know the end version of the epoch. Additionally,
the master recovery only needs to deal with crashed backup workers by
recruiting new workers to backup the unfinished version range.
Serialize pseudoLocalities if protocol version is larger than 0x0FDB00B061060001LL.
Note this version may need to be changed to "currentProtocolVersion" when merging
into the master, and "currentProtocolVersion" should be incremented.
We don't need to abide by object serializer rules yet, and the minor
change to Simulation config lets us test config being the default at the
start of the test.
* log_version in the database (`/conf/log_version`) is now a hint that gets
rounded to the nearest supported version.
* fdbcli and FDB enforce that only a valid log_version can be configured to
* TLogVersion is persisted in CoreTLogSet (and LogSet and TLogSet)
* Some comments here and there
* Add an assert on filename length to make sure KV-pairs in filename
don't exceed a maximum length.
