Various syntax fixes in sql/sql_yacc.yy for stored procedures:

Browse Source 
- No RESTICT|CASCADE in DROP SP (since it's not implemented)
  - Added optional "noise" to FETCH: [[NEXT] FROM]
  - At least one statement required in all block constructs except BEGIN-END
    (where zero is allowed)


mysql-test/r/sp.result:
  Modified test cases for optional [[NEXT] FROM] in FETCH.
mysql-test/t/sp.test:
  Modified test cases for optional [[NEXT] FROM] in FETCH.
