Since the mask is used in hot paths (e.g. access permission checks for each SNMP operation, the bitlist representation of the mask has benefits (e.g. faster processing).

Therefore, to fix the issue, convert between the bitlist (internal) representation and bitstring (external) when the vacmViewTreeFamilyMask objects are accessed.
Also, the check of the vacm config file was invalid with regard to the mask value. It was assumed to be a proper oid, which is not strictly the case (see bitlist above).
