It would be nice to expose 'pinfo->private_data' to the Lua interface.

It seems to me that 'pinfo->private_data' is the only way for C dissector and
Lua dissector to exchange user defined data with each other. For example, I use
private_data like following:

C dissector ---calls---> 
  Lua dissector ---calls--->
     functions to extract info from private_data in C dynamic library.
