Update git submodules

Update git submodules

* Update docs/submodules/sfc from branch 'master'
  - Move all test that work up

    Move all test that work up so that we can commit a patch to danube branch in
    which the seeds can go from 0 to 3, leaving 4 and 5 out of danube. This patch
    is separated from the danube patch because I think it is easier to have the
    same list in danube and master to avoid confusion
