Introduce the "show-dependencies" command and BuildDependencyGraph.

The "show-dependencies" command takes a series of build tuples and dumps
the resulting dependency graph (including strata and chunks at the
moment) to the standard output. It also dumps the resulting build order
which is a list of groups. These groups indicate which chunks and strata
can be built in parallel and are not dependent on each other.
