When `--recursive` and `--reference` is given, it is reasonable to
expect that the submodules are created with references to the submodules
of the given alternate for the superproject.
An initial attempt to do this was presented to the mailing list, which
used flags that are passed around ("--super-reference") that instructed
the submodule clone to look for a reference in the submodules of the
referenced superproject. This is not well thought out, as any further
`submodule update` should also respect the initial setup.
When a new submodule is added to the superproject and the alternate
of the superproject does not know about that submodule yet, we rather
error out informing the user instead of being unclear if we did or did
not use a submodules alternate.
To solve this problem introduce new options that store the configuration
for what the user wanted originally.

In a later patch we want to try to create alternates for submodules,
but they might not exist in the referenced superproject. So add a way
to skip the non existing references and report them.

Allow the user to pass in multiple references to update_clone.
Currently this is only internal API, but once the shell script is
replaced by a C version, this is needed.
This fixes an API bug between the shell script and the helper.
Currently the helper accepts "--reference" "--reference=foo"
as a OPT_STRING whose value happens to be "--reference=foo", and
then uses
if (suc->reference)
argv_array_push(&child->args, suc->reference)
where suc->reference _is_ "--reference=foo" when invoking the
underlying "git clone", it cancels out.
With this change we omit one of the "--reference" arguments when
passing references from the shell script to the helper.

There is an optimization used in "git diff $treeA $treeB" to borrow
an already checked-out copy in the working tree when it is known to
be the same as the blob being compared, expecting that open/mmap of
such a file is faster than reading it from the object store, which
involves inflating and applying delta. This however kicked in even
when the checked-out copy needs to go through the convert-to-git
conversion (including the clean filter), which defeats the whole
point of the optimization. The optimization has been disabled when
the conversion is necessary.

"git fetch" exchanges batched have/ack messages between the sender
and the receiver, initially doubling every time and then falling
back to enlarge the window size linearly. The "smart http"

Users of the parse_options_concat() API function need to allocate

Commit 959b5455 (submodule: implement a config API for lookup of
.gitmodules values, 2015-08-18) implemented the initial version of the
submodule config cache. During development of that initial version we
extracted the function gitmodule_sha1_from_commit(). During that process
we missed that the strbuf rev was still used in config_from() and now is
left empty. Lets fix this by also returning this string.
This means that now when reading .gitmodules from revisions, the error
messages also contain a reference to the blob they are from.
