Bug#17261 Passing a variable from a stored procedure to UDF crashes mysqld

Browse Source 
- Pass "buffers[i]" to val_str() in udf_handler::fix_fields insteead of NULL.
 - Add testcase for UDF that will load and run the udf_example functions 
   if available


sql/item_func.cc:
  Instead of passing a NULL pointer into val_str, use the "buffers" array to provide a temp string buffer.
sql/udf_example.cc:
  Spelling error"on"->"one"
