*  dissect_snmp_VarBind
*  this routine dissects variable bindings, looking for the oid information in our oid repository
*  to format and add the value adequately.
*
* The choice to handwrite this code instead of using the asn compiler is to avoid having tons
* of uses of global variables distributed in very different parts of the code.
* Other than that there's a cosmetic thing: the tree from ASN generated code would be so
* convoluted due to the nesting of CHOICEs in the definition of VarBind/value.
*
* XXX: the length of this function (~400 lines) is an aberration!
*  oid_key_t:key_type could become a series of callbacks instead of an enum
*  the (! oid_info_is_ok) switch could be made into an array (would be slower)

*
* The SNMP RFCs are silent on this (cf. L2TP RFC 2661, which
* supports using either the well-known port or an ephemeral
* port as the source port for responses, while noting that
* the latter can cause issues with firewalls and NATs.) so
* possibly some other implementations could do this.
*
* If this packet went to the SNMP port, we check to see if
* there's already a conversation with one address/port pair
* matching the source IP address and port of this packet,
* the other address matching the destination IP address of this
* packet, and any destination port.
*
* If not, we create one, with its address 1/port 1 pair being
* the source address/port of this packet, its address 2 being
* the destination address of this packet, and its port 2 being
* wildcarded, and give it the SNMP dissector as a dissector.
