This commit adds support for a new type of graph, showing the timeline of a build. It shows, with one line per package, when each of this package steps started/ended, and therefore allows to see the sequencing of the package builds. For a fully serialized build like we have today, this is not super useful (except to show that everything is serialized), but it becomes much more useful in the context of top-level parallel build. We chose to order the graph by the time-of-configure, as it is the closest to the actual cascade-style of a true dependency graph, which is tiny bit more complex to achieve properly. The actual result still looks pretty good. The graph-build make target is extended to also generate this new timeline graph.
