[AGENT++] Consts in SNMP++

Hi,

the const fixes will be in the next release.

:-) I would decide that the Address classes are not to be used between 
multiple threads. The same is true for Pdu, Vb, OctetStr,...

If you're only worried about the friendly_name method, I would suggest 
calling it once after creation of an address object. Or I could change any
iv_friendly_name[0] = 0 to memset(iv_friendly_name,...).
