bug #20152: mysql_stmt_execute() overwrites parameter buffers

Browse Source 
When using a parameter bind MYSQL_TYPE_DATE in a prepared statement,
the time part of the MYSQL_TIME buffer was written to zero in
mysql_stmt_execute(). The param_store_date() function in libmysql.c
worked directly on the provided buffer.
Changed to use a copy of the buffer.
