Broken compatibility of 2.4 server with 2.2 agent

Details

    Description

      When an active log item becomes unsupported, agent v. 2.2.2 used to send the following:

      [{
      	"request":"agent data",
      	"data":[
      		{
      			"host":"Zabbix server",
      			"key":"log[\/tmp\/log]",
      			"value":null,
      			"lastlogsize":8,
      			"clock":1423565589,
      			"ns":834122853}],
      	"clock":1423565590,
      	"ns":836189375}]
      

      and value null meant that item became unsupported. .

      2.4 agent sends a new field "state":1, meaning that the item is unsupported:

      [{
          "request":"agent data",
          "data":[
              {
                  "host":"Zabbix server",
                  "key":"log[/tmp/log]",
                  "value":"Cannot obtain information for file \"/tmp/log\": [2] No such file or directory",
                  "state":1,
                  "lastlogsize":8,
                  "clock":1423566013,
                  "ns":559885559}],
              "clock":1423566014,
              "ns":562135683}]
      

      But when 2.4 server receives packet of 2.2.2 agent, it perceives "value":null as a normal value, since there is no state field.
