copies: iterate over children directly (instead of parents)
Before this change we would gather all parent → child edges and iterate on
all parent, gathering copy information for children and aggregating them from
there.
They are not strict requirement for edges to be processed in that specific
order. We could also simply iterate over all "children" revision and aggregate
data from both parents at the same time. This patch does that.
It make various things simpler:
* since both parents are processed at the same time, we no longer need to
cache data for merge (see next changeset for details),
* we no longer need nested loop to process data,
* we no longer need to store partial merge data for a rev from distinct loop
interaction to another when processing merges,
* we no longer need to build a full parent -> children mapping (we only rely on
a simpler "parent -> number of children" map (for memory efficiency),
* the data access pattern is now simpler (from lower revisions to higher
revisions) and entirely predicable. That predictability open the way to
prefetching and parallel processing.
So that new iterations order requires simpler code and open the way to
interesting optimisation.
The effect on performance is quite good. In the worse case, we don't see any
significant negative impact. And in the best case, the reduction of roundtrip
to Python provide us with a significant speed. Some example below:
