[TRAFODION-1676] rework, fix executor regression test022 failures
rework of the JIRA, in previous code, it get display string length using
strlen(), but the srcData is not null-terminated for sure, so it will randomly
get some unknown content.
And also refactor the previous code for better coding rule.
This should address the sql regression failure of executor/TEST022.

> Project: Apache Trafodion
> Issue Type: Improvement
> Components: sql-exe
> Reporter: liu ming
> Assignee: liu ming
> Priority: Minor
> Fix For: 2.1-incubating
>
>
> A sql contains some SQL function, for example UPPER(), when the input data of
> UPPER() contains invalid data, UPPER() will fail. In this case, the whole
> query abort, and the error message cannot tell which row has invalid data, so
> it is very hard to fix the problem.
> It will be good to have row id or the real value of the error row in the
> error message to help trouble shooting.
