Check for G_GINT64_MODIFIER in Wireshark as we do in Wiretap.
In all the places where a cast to "long long" or "unsigned long long"
was done, use G_GINT64_MODIFIER and get rid of the cast, as
1) there's no guarantee that "%ll" works
and
2) there's no guarantee that "long long" works
(the latter definitely does *NOT* work with MSVC++; the former doesn't
work with regular printf in MSVC++, but it might work with the GLib
printf-based functions).
