[PATCH v4 0/2] submodule: move gitdir into superproject

Move git-dir for submodules into $GIT_DIR/modules/[name_of_submodule] of
the superproject. This is a step towards being able to delete submodule
directories without loosing the information from their .git directory
as that is now stored outside the submodules work tree.

This is done relying on the already existent .git-file functionality.
Tests that rely on .git being a directory have been fixed.

This is the forth iteration of this patchseries.
