Don't put them in the summary structure; the summary routines should calculate summary statistics, not dig up every bit of information that *could* appear in a summary. Instead, have the GUI code call wtap_file_get_shb() to get the SHB information and call wtap_optionblock_get_option_string() to fetch the option values. Move the option code definitions into wtap_opttypes.h, as they're used by the API.
