This patch adds create and destroy function for XenBlockDevice-s so that they can be created automatically when the Xen toolstack instantiates a new PV backend via xenstore. When the XenBlockDevice is created this way it is also necessary to create a 'drive' which matches the configuration that the Xen toolstack has written into xenstore. This is done by formulating the parameters necessary for each 'blockdev' layer of the drive and then using qmp_blockdev_add() to create the layers. Also, for compatibility with the legacy 'xen_disk' implementation, an iothread is automatically created for the new XenBlockDevice. This, like the driver layers, will be destroyed after the XenBlockDevice is unrealized. The legacy backend scan for 'qdisk' is removed by this patch, which makes the 'xen_disk' code is redundant. The code will be removed by a subsequent patch.
