…ead-safe The `vc->add_to_keep_alive_queue()` is called by: - Http1ClientSession::release() - Http2ClientSession::cleanup_streams() - Http2ClientSession::release_stream() And the `NetHandler::remove_from_active_queue()` is called by `vc->add_to_keep_alive_queue()`. The NetHandler::keep_alive_queue and NetHandler::active_queue are internal queue of NetHandler. We must have acquired the NetHandler's lock before doing anything with them. When reenable a HttpSM from plugin, the HttpSM would be run into ethread that different from client_vc lives because TSHttpSMCallback is scheduled by `eventProcessor.schedule_imm()`. (cherry picked from commit c929ed6)
