[snmp] AsnUnsInteger64

[Tim Panton]

Yes, you are right - A while back we went through changing all the  
UnsignedInt32's to be stored as long.
At the time I decided not to do the 64's as it would break the ability  
to use the stack in J2ME.
(CLDC) as it didn't have any of the BigInteger classes.

Since (as far as I'm aware) no one is using the stack on J2ME I guess  
we should fix it.

Tim.
