prop224: Clang compile error + bad log_warn on master
Seems like we failed a bit on the latest merges and we introduced a compile error: ``` In file included from src/or/directory.c:21: src/or/directory.h:191: error: redefinition of typedef ‘response_handler_args_t’ src/or/directory.h:181: note: previous declaration of ‘response_handler_args_t’ was here ``` and also a stray and loud `log_warn`: ``` [warn] No change in hsdir set! ``` We need to fix these!
