Great, thanks to both Guy and Jaap for their suggestions. I also
looked at PLY (http://www.dabeaz.com/ply/ply.html) but that seems to
involve a fair amount of work and would be similar to the approach I
took with the SMB dissector a long time ago.
I will look at both of those and see which will be easier of the three
approaches I have so far.
Modifying a version of rpcgen has some attraction since it means that
the same tool can be used to generate a Wireshark dissector as is used
to generate the stubs etc.
