[libvirt] [test-API][PATCH v2 2/2] Add and update functions in streamAPI

[Wayne Sun]

  * accpet connection object and stream flag as parameter in __init__
    remove connect function for connction is given in as parameter.

  * remove newStream() from each function
    create new stream object in __init__.
    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.
