Detailed Description

Elements used to identify conversations for *_full routines and pinfo->conv_elements. Arrays must be terminated with an element .type set to CE_CONVERSATION_TYPE.

This is currently set only by conversation_set_elements_by_id(); it is not set for conversations identified by address/port endpoints.

In find_conversation_pinfo() and find_or_create_conversation(), if any dissector has set this, then, unless some dissector has set the pair of address/port endpoints (see below), the array of elements is used to look up or create the conversation. Otherwise, the current addresses and ports in the packet_info structure are used.

XXX - is there any reason why we shouldn't use an array of conversation elements, with the appropriate addresses and ports, and set it for all protocols that use conversations specified by a pair of address/port endpoints? That might simplify find_conversation_pinfo() by having them always use the array of elements if it's present, and just fail if it's not.
