Fixes for timing logger and histogram.

Reorder when the index is checked in Percentile to avoid reading from a
negative index.
Add missing copyright to histogram unit test.
Switch histogram test to use UniquePtr rather than new/delete (MeanTest had
missed the delete).
Make timing/cumulative logger fields that can be const const. Document SetName
for cumulative logger. Place the cumulative logger's std::string lock name in
the cumulative logger so its lifespan is clearly the same.
