[AGENT++] Asn1 class hierarchy and smival

because Jeff Meyer designed it that way and nobody changed it until now ;-)

Are there any classes that inherit from SnmpSyntax that do not use
smival to store the value?

The smival is passed to other functions and these no longer have access
to the SnmpSyntax subclass, but need to know the syntax.
