During startup or after restart we go through ap_open_logs() and thus

after startup or restart, the write side of the original pl is closed and the pipe is written to via the duped FD in stderr. More precisely ap_open_logs() calls open_error_log(), which returns ap_piped_log_write_fd(pl) in s->error_log, and after return ap_open_logs() calls apr_file_close(s_main->error_log) is s==s_main.

When killing the logger, piped_log_maintenance() gets called. It can now not simply use pl, because the write side has been closed before in ap_open_logs(). I tried to keep the startup behaviour during restart, so I dup stderr to
restart -> restart of a killed logger
the write side in the maintenance function, spawn and close the write side again.
