I have attached patches for bug # 50755 on bugs.php.net. These also
cleanup to PDO DBLIB code to have less of a memory footprint and to
prepare for other feature additions such as multiple rowset support.

I have compiled and tested on x86.

Can someone review and provide feedback. PDO devs seem to be busy. Thank you.
