graphlog: add a way to test the 'groupbranchiter' function

We add an experimental config option to use the topological sorting. I first
tried to hook the 'groupbranchiter' function in the 'sort' revset but this was useless
because graphlog enforces revision number sorting :(

As the goal is to advance on the topological iteration logic, I see this
experimental option as a good way to move forward.

We have to use turn the iterator into a list because the graphlog is apparently
not ready for pure iterator input yet.

Test modifying an unknown file

  $ hg revert -aq

Test removing an unknown file

  $ hg up -qC 0

Test copying onto an unknown file
