"dissector" union in the "conversation_t" structure to "old_d" and "new_d", to avoid using a C++ reserved word. Add "old_conversation_set_dissector()" and "conversation_set_dissector()" routines to set the dissector for a conversation, to hide the details of how that's done (e.g., details such as whether there's a union at all - eventually, when all dissectors have been tvbuffified, there won't be a need for the union - and what the names of the union members are, and so on). Convert all dissectors to use those routines (they had to be changed anyway, due to the name change). svn path=/trunk/; revision=2324
