Hello,
attached is the patch for the implementation of SNMPv3. I've been testing it on my system and devices, and it seems to be working properly. Since it's a core function of the soft, I guess it would be good that other people give it a try before it is committed.
I use NET-SNMP version: 5.4.3.
Be careful that a few files use direct calls to net-snmp instead of calling observium library functions. It means that those calls will not work with an snmpv3 device.

I will send a patch to fix cisco-vrf after this mail, but the other files will still be incompatible with snmpv3 (keep your devices in SNMPv2 if you use any of the incompatible calls).
