3. rgw: add pipe fd to set for select() in do_curl_wait() …

   when HAVE_CURL_MULTI_WAIT is 0, the pipe fd is never added to the
   readfds for select(), so FD_ISSET() is always false. this prevents us
   from ever trying to read from the fd, and the pipe's buffer eventually
   fills up and deadlocks callers of RGWHTTPManager::signal_thread() when
   they try to write to the pipe

10. rgw: add missing mutex header for std::once_flag …

    this fix was added directly to the jewel branch rather than backporting
    from master, because the code on master compiles without this specific
    include - it's likely included by another header, but backporting would
    involve pulling in unrelated changes
