enum type annotation: add portable column  type
-----------------------------------------------

                 Key: HHH-5667
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5667
             Project: Hibernate Core
          Issue Type: Improvement
          Components: annotations
         Environment: ALL
            Reporter: Dave


enum type ordinal values are mapped to integer type column. For most cases, they should be mapped to
byte type, for example, smallint(2) for mysql.

public Fruit {
public enum Color {
RED,
YELLOW
}

@Column(columnDefinition="smallint(2)")
private Color getColor() { ...
}
}

The annotation above is not portable. For an application with more than 100 enum types, an portable annotation for column type is needed. For example,

@Column(equivalentType=Byte.class)
private Color getColor() { ...
}

it says: mapping the enum type is equivalent to mapping a byte type.
