[libvirt] [RFC 0/2] util: introduce timeout mode in virCommandRun/Async and virKModLoad

Hi, everyone! It's possible that the running-time of a command is long than its caller expected. Perhaps, it's useful to provide timeout mode for virCommandRun or virCommandRunAsync + virCommandWait. And The caller can restrict the running time of the command if necessary. I introduce a new function virCommandSetTimeout for that. And then, virKModLoad will get a default timeout of 3 seconds. I hope it could solve the problem of "strange delay" as John mentioned. Thanks!
