[PATCH v3 0/2] submodule: move gitdir into superproject

[Fredrik Gustafsson <iveqy@iveqy.com>]

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 third iteration of this patchseries. In this iteration the
commit message of the second patch is updated and the fixup-patch from
Junio squashed with the first commit.
