A wireshark plugin must declare what major and minor version it was built with as these are checked when wireshark loads plugins. On the top of that, we use major + minor + micro to adapt to changed API between releases. So far, we were getting these version numbers from wireshark/config.h. And while most distributions install wireshark/config.h file some don't. On distros shipping it it's hack^Wsaved during built by packaging system and installed later. But some distros are not doing that. At least not for new enough wireshark because as of wireshark's commit v2.9.0~1273 the ws_version.h is installed which contains the version macros we need and is installed by wireshark itself. But of course, some distros which have new enough wireshark packaged do not ship ws_version.h and stick to the hack. That is why we can't simply bump the minimal version and switch to the new header file. We need a configure check and adopt our code to deal with both ways. At least for the time being.
