There have been quite a lot of changes in rtpengine module mainly relate 
to the possibility to store/get rtpengine machine URL in/from database.

Among those changes, [1] has been introduced also. This is useful when 
you have many sets of rtpengine stored in database and want to select 
the active set, currently possible only at startup-time (devault those 
with setid 0). A further improvement here would be to be able to "kamctl 
fifo change it".

The message notices that you should set [1] to your wanted, active set.

Now, having "modparam("rtpengine", "setid_avp", "$avp(setid)")" 
overwrites [1]'s behaviour, explaining why it's "found, support for it 
enabled".
