[PATCH v4 01/12] libqos/qgraph: add qemu_name to QOSGraphNode

[Christian Schoenebeck <qemu_oss@crudebyte.com>]

Add new member variable 'qemu_name' to struct QOSGraphNode.

This new member may be optionally set in case a different
name for the node (which must always be a unique name) vs.
its actually associated QEMU (QMP) device name is required.
