I just committed some patches for prepare/execute performances. First  
prepare using tds7+ is always defered as ms drivers do. For this  
reason if you bind afterthe prepare server receive a single prepare,  
not two. Prepexec is used to collapse prepare and execute. So now a  
sequence like SQLPrepare/SQLBindParameter/SQLExecute can lead to' only  
2 round trips instead of 6.

All tests passed, even perl ones.
