From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>
The bitmap_builder_init() method walks the reachable commits in
topological order and constructs a "reverse graph" along the way. At the
moment, this reverse graph contains an edge from commit A to commit B if
and only if A is a parent of B. Thus, the name "children" is appropriate
for for this reverse graph.
In the next change, we will repurpose the reverse graph to not be
directly-adjacent commits in the commit-graph, but instead a more
abstract relationship. The previous changes have already incorporated
the necessary updates to fill_bitmap_commit() that allow these edges to
not be immediate children.
