[PATCH v2 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 second iteration of this patchseries. The first can be found here: http://thread.gmane.org/gmane.comp.version-control.git/177582
