copies: simplify the handling of merges
Instead of stacking copies for both parent on the head, we move copies outside
of the heap into a dedicated dictionary. The two side of merge can we merged
sooner, making the algorithm simpler.
This simplicity reflect in the heap structure and speed up the execution for
copies involving a large amount of merges.
Here are timing for perfpathcopies of multiple revision pairs.
