PATCH: allow detail listeners to write to other files

I noticed[1] that detail listeners refuse to write detail entries to files, even if the destination filename is different from the source filename. The attached patch fixes that. It also centralizes the listen_detail_t definition, removing the 'stub' definition in src/main/event.c. john [1] https://lists.freeradius.org/pipermail/freeradius-users/2009-October/msg0018... -- John Morrissey _o /\ ---- __o jwm@horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__
