    rpcsvc: scale rpcsvc_request_handler threads
    
    Scale rpcsvc_request_handler threads to match the scaling of event

    protocol/client: fix memory corruption
    
    There was an issue when some accesses to saved_fds list were
    protected by the wrong mutex (lock instead of fd_lock).
    
    Additionally, the retrieval of fdctx from fd's context and any
    checks done on it have also been protected by fd_lock to avoid
    fdctx to become outdated just after retrieving it.
