Subject: Support virDomainPinIOThread

Support the libvirt_virDomainSetIOThreads method using code that mimics
the existing libvirt_virDomainPinVcpuFlags method

The following is a sample session assuming guest 'iothr-gst' has IOThreads
configured (it's currently running, too)

>>> import libvirt
>>> con=libvirt.open("qemu:///system")
>>> dom=con.lookupByName('iothr-gst')
>>> dom.ioThreadsInfo()
[(1, [False, False, True, False]), (2, [False, False, False, True]), (3, [True, True, True, True])]
>>> cpumap=(True,True,True,False)
>>> dom.pinIOThread(3,cpumap)
0
>>> print dom.ioThreadsInfo()
[(1, [False, False, True, False]), (2, [False, False, False, True]), (3, [True, True, True, False])]
>>>
