Michal Privoznik caa9560c15 wireshark: Prefer ws_version.h over config.h
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.
