submodule--helper: introduce add-clone subcommand
Let's add a new "add-clone" subcommand to `git submodule--helper` with the goal of converting part of the shell code in git-submodule.sh related to `git submodule add` into C code. This new subcommand clones the repository that is to be added, and checks out to the appropriate branch. This is meant to be a faithful conversion that leaves the behaviour of 'cmd_add()' script unchanged.
