setup: introduce GIT_DEFAULT_REF_FORMAT envvar
Introduce a new GIT_DEFAULT_REF_FORMAT environment variable that lets
users control the default ref format used by both git-init(1) and
git-clone(1). This is modeled after GIT_DEFAULT_OBJECT_FORMAT, which
does the same thing for the repository's object format.
