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.

  $ hg init

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
