[libvirt] [PATCH] python: make virDomainSetSchedulerParameters accpet integer argument

[Guannan Ren]

    When sending a Python integer as an argument to
    PyLong_AsUnsignedLong or PyLong_AsUnsignedLongLong,
    the following error occurs

    SystemError: Objects/longobject.c:980:
    bad argument to internal function

    This error comes from the fact that
    PyLong_AsUnsignedLong and PyLong_AsUnsignedLongLong,
    unlike PyLong_AsLong or PyLong_AsLongLong, does not check
    to see if the number is a long or integer, but only a long.

    The regression is introduced by
    9c8466daac19379c41be39ec8f18db36c9573c02

    >>> dom.setSchedulerParameters({'cpu_shares': 1024})
    0
    dom.schedulerParameters()
    {'cpu_shares': 1024L}
    >>> dom.setSchedulerParameters({'cpu_shares': 1024L})
    0
    >>> dom.schedulerParameters()
    {'cpu_shares': 1024L}
