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])] >>> merge
