Procedure analyse() redefines select's fields_list. setup_copy_fields() assumes
that fields_list is a part of all_fields_list. Because select have only 
3 columns and analyse() redefines it to have 10 columns, int overrun in
setup_copy_fields() occurs and server goes to almost infinite loop.

Because fields_list used not only to send data ad fields types, it's wrong 
to allow procedure redefine it. This patch separates select's fileds_list 
and procedure's one. Now if procedure is present, copy of fields_list is 
created in procedure_fields_list and it is used for sending data and fields.
