Bug #851 mysql_stmt_num_rows not implemented?

Description:
The documentation (Section 9.1.7.12) states that there is a function mysql_stmt_num_rows, but it's not in any of the include files. Would be very nice to have.

How to repeat:
# grep num_rows /usr/include/mysql/*

/usr/include/mysql/mysql.h:my_ulonglong STDCALL mysql_num_rows(MYSQL_RES *res);

Suggested fix:
Implement it!
