Avoid holding the rowlock during HLog sync in HRegion.mutateRowWithLocks
------------------------------------------------------------------------

                 Key: HBASE-5541
                 URL: https://issues.apache.org/jira/browse/HBASE-5541
             Project: HBase
          Issue Type: Sub-task
            Reporter: Lars Hofhansl
            Assignee: Lars Hofhansl
             Fix For: 0.94.0


Currently mutateRowsWithLocks holds the row lock while the HLog is sync'ed.
Similar to what we do in doMiniBatchPut, we should create the log entry with the lock held,
but only sync the HLog after the log is released, along with rollback logic in case the sync'ing
fails.
