[libvirt] [test-API][PATCH 2/2] Add and update functions in streamAPI



  * only accpet stream object as parameter in __init__

  * remove newStream() from each function
    stream object should be pass in as parameter, not create new at
    each function.
    function also need flags parameter.

  * Add 5 new functions
    screenshot(self, domain, screen, flags = 0)
    download(self, vol, offset, length, flags = 0)
    upload(self, vol, offset, length, flags = 0)
    recvAll(self, handler, opaque)
    sendAll(self, handler, opaque)

    for recvAll and sendAll, handler is a user defined function which
    write/read data to/from file.
