Subject: [PATCH] fix 'git add' to skip submodules configured as ignored

If submodules are configured as ignore=all they are not shown by status.
Lets also ignore them when adding files to the index. This avoids that
users accidentially add ignored submodules with: git add .

We achieve this by reading the submodule config and thus correctly
initializing the infrastructure to take the ignore decision.
