/**
   Fetches all "technote" (formerly "event") IDs from the repository
   and appends each one to the given list in the form of a
   (`char*`). This function relies on the `event-` tag prefix being
   reserved for technotes and that the technote IDS are all exactly 40
   bytes long.
   
   Returns 0 on success, FSL_RC_NOT_A_REPO if f has no repository db
   opened, FSL_RC_OOM if allocation of a new list entry fails, or
   propagates db-related code on any other error. Results are
   undefined if either argument is NULL.

   TODO? Reformulate this to be like fsl_tkt_id_to_rids(), returning
   the list as RIDs?
