          <p>[manager] When information from an unknown agent is received,

            The problem was that the <c>TargetName</c> argument was useless

          <p>[manager] A major flaw was discovered with the agent handling. </p>
          <p>First, <c>TargetName</c> was never used as intended, as a unique
            identifier for the target (agent in this case). </p>
          <p>Second, <c>TargetName</c> had a <em>default value</em>, which meant 
            that several agents could have the same <c>TargetName</c>, causing
            unpredictable behaviour in the manager. </p>
          <p>Third, <c>EngineID</c> was not a mandatory config option and had
            furthermore also a <em>default value</em>. </p>

          <p>These problems has been solved in the following way: </p>
          <p>First, a new set of api functions has been introduced (and documented):
            <seealso marker="snmpm#register_user">register_user/4</seealso>,
            <seealso marker="snmpm#register_user_monitor">register_user_monitor/4</seealso>,
            <seealso marker="snmpm#register_agent">register_agent/3</seealso>,
            <seealso marker="snmpm#unregister_agent">unregister_agent/2</seealso>,
            <seealso marker="snmpm#agent_info">agent_info/2</seealso>,
            <seealso marker="snmpm#update_agent_info">update_agent_info/4</seealso>,
            <seealso marker="snmpm#sync_get">sync_get/3,4,5,6</seealso>,
            <seealso marker="snmpm#async_get">async_get/3,4,5,6</seealso>,
            <seealso marker="snmpm#sync_get_next">sync_get_next/3,4,5,6</seealso>,
            <seealso marker="snmpm#async_get_next">async_get_next/3,4,5,6</seealso>,
            <seealso marker="snmpm#sync_set">sync_set/3,4,5,6</seealso>,
            <seealso marker="snmpm#async_set">async_set/3,4,5,6</seealso>,
            <seealso marker="snmpm#sync_get_bulk">sync_get_bulk/5,6,7,8</seealso> and
            <seealso marker="snmpm#async_get_bulk">async_get_bulk/5,6,7,8</seealso> 
            that all use <c>TargetName</c> (and not, as previously, <c>Addr</c>
            and <c>Port</c>) to identify the agent (also the return value of 
            <seealso marker="snmpm#which_agents">which_agents</seealso> has 
            been changed). </p> 
          <p>Second, for backward compatibility, the old functions still 
            exist, but are no longer documented and are now wrappers for the 
            new functions, including erroneous default value for EngineID and 
            all. The TargetName is however generated from the provided 
            <c>Addr</c>, <c>Port</c> and <c>Version</c> config options. </p>
           <p>Third, the behaviour of the 
             <seealso marker="snmpm_user">SNMP manager user</seealso> has
             been changed to reflect this, i.e. 
             <seealso marker="snmpm_user#handle_pdu">handle_pdu/4</seealso>,
             <seealso marker="snmpm_user#handle_trap">handle_trap/3</seealso>,
             <seealso marker="snmpm_user#handle_inform">handle_inform/3</seealso>, 
             <seealso marker="snmpm_user#handle_report">handle_report/3</seealso> 
             and the return-value of 
             <seealso marker="snmpm_user#handle_agent">handle_agent/4</seealso>.
             The old (non-documented) callback-functions (using Addr and Port) 
             will still be called if the agent was registered using the old 
             registration functions. </p>
