I believe g_log and friends go to standard out, but maybe not on all
platforms. An expert info under conditional compilation would probably
be enough though, I hadn't thought of that.

Another question. I've found a promising point to put the check (packet.c:call_dissector_with_data()). This function is called many times (I can count 4 times per packet). Sometimes when tree is open, sometimes when it's closed. How can I navigate (and check) the tree only and only if it's open? 
Only in this case I can check if there are undecoded bytes.
