DISKUSED used 64bit counter if with -V 2c, fix 32bit

On big volumes (bigger then 32bit counter = 4GB) overflow to
negative values. SNMP on version 2c can transport 64bit value,
it's not necessary using Low and High 32bit part of 64bit number.
Fix DISKUSED on SNMPv1 if using more then 4GB of space.

New _ulong64() function for counting 64bit number from its high
and low 32bit parts. This function computing correct 64bit number
on 32bit operating system.
