Probe firmware version 4480

• Fixed bug in traceroute when it has to deal with rfc4884 objects (mpls) that have a wrong size.
• Delayed DNS name resolution in ping and traceroute. This feature will soon be enabled through the UI.
• Fixed bug in HTTP GET where some characters where not properly escaped in generating the result JSON.
• Fixed bugs in the libevent stub resolver to better handle DNS errors and timeouts (affects mostly httpget)
• Limit the amount of measurement data that is sent as one unit. This prevents probes that have not connected to a controller for some time from overloading the controller.
• The probe uptime is now in the DNS SOS messages that are sent by probes before they try to connect. This will allow making a distinction between various reasons for disconnects: e.g. probe reboot vs. network problems.
• Initial version for anchor package added (Anand Buddhev)
