Bug #10708 SP's can use INFORMATION_SCHEMA as ROUTINE_SCHEMA

Description:
It should not be allowed to use INFORMATION_SCHEMA as ROUTINE_SCHEMA (see how to repeat).

select routine_catalog, routine_schema, routine_name from information_schema.routines where routine_schema='information_schema'  returns:
+-----------------+--------------------+--------------+
| routine_catalog | routine_schema     | routine_name |
+-----------------+--------------------+--------------+
| NULL            | information_schema | p1           |
+-----------------+--------------------+--------------+

How to repeat:
\d |

# this should return an error:
# ERROR 1049 (42000): Unknown database 'information_schema'
CREATE PROCEDURE information_schema.p1 ()
BEGIN
  SELECT 'foo' FROM DUAL;
END |

#but this works
USE information_schema |
CREATE PROCEDURE p1 ()
BEGIN
  SELECT 'foo' FROM DUAL;
END |
