branch into the v3.0 branch.

* Make AuthzManager logOp listener rollback-safe
* Make MigrateFromStatus logOp listener rollback-safe
* Make dbhash and storedFuncMod logOp listeners rollback-safe
* Remove RollBackPreventer since all logOp listeners are now rollback-safe
* Do not perform a query while committing.
