A tough call. If we go C++ we should have a plan to use the STL classes with our
concept of memory (allocator scope). I've started a short discussion last year,
but somebody found out, that using STL objects on the heap with the C++
allocators doesn't have the same semantics (and really doesn't work) with our
packet or file lifetime scopes.

However a second approach with C++ objects managed by smart pointers and those
smart pointers being aware of the packet/file/application lifetime might work.
We should research this, write guidelines how to use C++ objects in Wireshark
and then make a decision if we want to allow C++ features everywhere.

Another advantage would be that we can use real C++ exceptions.
