Currently, if qos_node_contains was passed options, it would still
create an edge without any options. Instead, in that case
NULL acts as a terminator.

The test uses the trick:
if (!opts) {
opts = &(QOSGraph...Options) { };
}
in a couple of places, however the temporary created
by the &() {} goes out of scope at the bottom of the if,
and results in a seg or assert when opts-> fields are
used (on fedora 30's gcc 9).

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
