Stefan Beller fb43e31f2b submodule: try harder to fetch needed sha1 by direct fetching sha1
When reviewing a change that also updates a submodule in Gerrit, a
common review practice is to download and cherry-pick the patch
locally to test it. However when testing it locally, the 'git
submodule update' may fail fetching the correct submodule sha1 as
the corresponding commit in the submodule is not yet part of the
project history, but also just a proposed change.

If $sha1 was not part of the default fetch, we try to fetch the $sha1
directly. Some servers however do not support direct fetch by sha1,
which leads git-fetch to fail quickly. We can fail ourselves here as
the still missing sha1 would lead to a failure later in the checkout
stage anyway, so failing here is as good as we can get.

# The function takes at most 2 arguments. The first argument is the

# argument, if specified, is the relative path that navigates
# from the submodule working tree to the superproject working tree.
#
# The output of the function is the origin URL of the submodule.

# The output will either be an absolute URL or filesystem path (if the
# superproject origin URL is an absolute URL or filesystem path,

# origin URL is a relative file system path).
