[AGENT++] SNMP++ Implementation of Address Types

some of this duplicate code cannot be avoided:
IpAddress::IpAddress(const IpAddress& other) can be called wit a
UdpAddress, so this constructor has to set smival.syntax to
sNMP_SYNTAX_IPADDR.

IpAddress and UdpAddress have their own output_buffer, so doing all in
Address constructor won't be possible.

I'll see if something can be simplified.
