Bug Description

If, for some reason, the IP address of a monitored IP Device has multiple PTR records in the DNS, NAV's chosen sysname for this device may swing back and forth. The order of the returned records may be random on each DNS response, but the dnsname plugin will always pick the first record in the response.

ipdevpoll should prefer stability in this case: It should examine all the PTR records if there are multiple, and if any of the correspond with the existing sysname of the device, keep that name unchanged. If there is no match, it can pick the first one, as before.
