Fixed SELECT INTO OUTFILE/DUMPFILE and stored procedures, and extended and 

reorganized the sp.test file.


mysql-test/r/sp.result:
  New results from the reorganized sp.test file.
mysql-test/t/sp.test:
  Reorganized the tests, and added a few new ones. ("fac" and more "select into")
sql/sql_class.cc:
  Unlock tables and set thd->lock=0 in select_export::send_eof() and
  select_dump::send_eof().
  This fixes a problem with an assert() in lock_tables(), and made
  SELECT ... INTO OUTFILE and ... INTO DUMPFILE work in stored procedures.
