Add qgraph API that allows to add/remove nodes and edges from the graph, implementation of Depth First Search to discover the paths and basic unit test to check correctness of the API. Included also a main executable that takes care of starting the framework, create the nodes, set the available drivers/machines, discover the path and run tests. graph.h provides the public API to manage the graph nodes/edges graph_extra.h provides a more private API used successively by the gtest integration part qos-test.c provides the main executable Signed-off-by: Emanuele Giuseppe Esposito <e.emanuelegiuseppe@gmail.com> [Paolo's changes compared to the Google Summer of Code submission: * added subprocess to test options * refactored object creation to support live migration tests * removed driver .before callback (unused) * removed test .after callbacks (replaced by GTest destruction queue)] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
