[PATCH v2 1/2] parse-remote: move used code to git-submodule.sh

[Junio C Hamano <gitster@pobox.com>]

From: Ævar Arnfjörð Bjarmason <avarab@gmail.com>

Move the get_default_remote () helper from git-parse-remote.sh to
git-submodule.sh, as the latter is the only user.

There are two more helper functions, get_remote_merge_branch() and
error_on_missing_default_upstream(), in the git-parse-remote shell
function library, but they are not referenced by git-submodule.sh;
stop dot-sourcing the git-parse-remote.
