fix: mutex leak, errno-after-free, log_perror misuse, status validation

Browse Source 
- multiprocessing: destroy mutex_progress on the dir_entries_mutex
  init-failure path (init >= 7); drop bogus log_perror
- delete_plan: capture errno before free() in apply_deferred_path
- queue/array_list: log_message instead of log_perror for non-errno
  conditions
- protocol: reject unknown wire Status values via status_is_valid() in
  receive_status, receive_status_timed and the keepalive reader; declare
  protocol_receive_status_timed in protocol.h
- protocol: %llu for unsigned long long debug counters
- tests: out-of-range status rejection test
