Allow ignoring submodules (or not) by command line switch, like diff
and status do.
This commit is also a prerequisite for the next one in series, which
adds the --ignore-submodules switch to git commit. That's why a new
argument is added to public function add_files_to_cache(), and it's
call sites are updated to pass NULL.

Git add currently doesn't honor ignore setting from .gitmodules or
.git/config, which is related functionality, however I'd like to
change that in another patch, coming soon.
Changes against v4 of this patch:
* fixed file mode of added test script (644 -> 755)
* cleaned up commit message
