That's because a) the created qos node names must always be unique, b) the node name must match the official QEMU driver name being instantiated and c) all nodes are in a global space shared by all tests. This patch removes this limitation by introducing a new function qos_node_create_driver_named() which allows test case authors to specify a node name being different from the actual associated QEMU driver name. It fills the new 'qemu_name' field of QOSGraphNode for that purpose. Adjust build_driver_cmd_line() and qos_graph_node_set_availability() to correctly deal with either accessing node name vs. node's qemu_name correctly.

Let's make this clear by changing the prefix of the individual qtest case names from 'fs/' to 'synth/'. That way they'll be easily distinguishable from upcoming new 9pfs test cases supposed to be using a different fs driver.

In this initial version, there is only one local test which actually only checks if the 9pfs 'local' device was created successfully. Before the 9pfs 'local' tests are run, a test directory 'qtest-9p-local' is created (with world rwx permissions) under the current working directory. At this point that test directory is not auto deleted yet.
