Used to convert 64bit to 32bit. It is better to saturate 32bit during
conversion than just passing 32 LSB bits.

snmp_get_next works only when requesting oid is valid. Otherwise it fails to
find next entry.

Due to the above the snmpwalk works only when the walk is started from
the existing oid. Since snmp walk scans only oids in the current branch,
there was a need to create a special oid .1.3.

$ snmpwalk -On -c public -v 1 192.168.1.20 1.3
.1.3.6.1.2.1.1.5.0 = STRING: "wrc"
.1.3.6.1.2.1.25.1.1.0 = Timeticks: (792773) 2:12:07.73

Timeout: No Response from 192.168.1.20

NOTE: Timeout message appears becasue there is no responce from node when
wrong packet is sent.

The "community" string is public. We have tree items only: the host
name, the date and uptime.

The code is designed to make it simple any addition. But we only have
snmpget support, not snmpwak (i.e. "get next" query).

This is run on an host build (CONFIG_HOST_PROCESS) where the time and
date are not related to the real world:

   # snmpget -v 1 -c public 192.168.16.1 .1.3.6.1.2.1.1.5.0
   SNMPv2-MIB::sysName.0 = STRING: wrc
   # snmpget -v 1 -c public 192.168.16.1 .1.3.6.1.2.1.25.1.2.0
   HOST-RESOURCES-MIB::hrSystemDate.0 = STRING: 1970-0-1,19:52:34.0
   # snmpget -v 1 -c public 192.168.16.1 .1.3.6.1.2.1.25.1.2.0
   HOST-RESOURCES-MIB::hrSystemDate.0 = STRING: 1970-0-1,19:53:2.0
   # snmpget -v 1 -c public 192.168.16.1 .1.3.6.1.2.1.25.1.1.0
   [...] hrSystemUptime.0 = Timeticks: (94193300) 10 days, 21:38:53.00
