BTW
Putting (doxygen) comments in the code helps :-)

Hi,
I try to keep up with the API changes so changing the API is no big problem as 
long as I understand what to do :-) Regards Anders

BTW, is changing the wtap_register_open_info() function prototype/ABI again 
soon going to cause you problems?

I ask because it changes again, with an additional argument, in here:
https://code.wireshark.org/review/#/c/431/

The additional argument is for whether the wiretap reader being registered 
should be put at the top or bottom of its respective magic/heuristic section.  
For example if it's a heuristic type, is it a strong vs. weak heuristic.

But if it would be painful for you, I can change that to keep the current 
wtap_register_open_info() as is, and make a new internal one that the existing 
wtap_register_open_info() can then just call with the default argument (which 
is for a weak heuristic).
