Bug #56804 Errors would not be reported in bulk upload

Description:
In bulk upload mode, SQLExecute would return SQL_SUCCESS, even when the upload data contains errors, such as primary duplication, foreign key violation, etc. 

A repro is attached.  If you run the repro against a database from all the other vendors, such as Oracle, Microsoft SQL Server, Sybase ASE, DB2, Sybase SQL Anywhere, SQLExecute will return SQL_ERROR or SQL_SUCCESS_WITH_INFO.

How to repeat:
Here are the steps to run the repro:
1) Detach the zip file and unzip it;
The zip file contains two files, odbcbug.exe (executable for running on Windows x86) and odbcbug.c (the source code used to build odbcbug.exe).
2) Issue the following command line:
  odbcbug "dsn=...;uid=...;pwd=..."
you'll see SQLExecute returns 0

"If an error occurred, the driver sets the corresponding value in the parameter status array to SQL_PARAM_ERROR and returns SQL_SUCCESS_WITH_INFO." And looks like we don't do that

Pushed to the trunk as rev#930
