Make the SNMP dissector use the ASN.1 code, rather than the SNMP library

code, to dissect SNMP PDUs; use the SNMP library code only to translate
OIDs into strings.

Put into the ASN.1 code an annoying hack to cope with the fact that UCD
SNMP makes an OID out of "u_long"s whilst CMU SNMP makes it out of
"u_int"s - have the ASN.1 code make it out of "subid_t"s, and typedef
"subid_t" appropriately depending on the SNMP library you have.

Eventually, we should be able to use "libsmi" instead of a full-blown
SNMP library, and thus possibly work around various aggravations with
the SNMP libraries.
