Subject: [PATCH] submodule: add get_submodule_config helper funtion

Several submodule configuration variables
(e.g. fetchRecurseSubmodules) are read from .gitmodules with local
overrides from the usual git config files.  This shell function mimics
that logic to help initialize configuration variables in
git-submodule.sh.
