When an error occurs in updating the working tree of a submodule in
submodule_move_head, tell the user which submodule the error occurred in.
The call to read-tree contains a super-prefix, such that the read-tree
will correctly report any path related issues, but some error messages
do not contain a path, for example:
~/gerrit$ git checkout --recurse-submodules origin/master
~/gerrit$ fatal: failed to unpack tree object 07672f31880ba80300b38492df9d0acfcd6ee00a

When a submodules work tree is removed, we should unset its core.worktree
setting as the worktree is no longer present. This is not just in line
with the conceptual view of submodules, but it fixes an inconvenience
for looking at submodules that are not checked out:
git clone --recurse-submodules git://github.com/git/git && cd git &&
git checkout --recurse-submodules v2.13.0
git -C .git/modules/sha1collisiondetection log
fatal: cannot chdir to '../../../sha1collisiondetection': \
No such file or directory
With this patch applied, the final call to git log works instead of dying
in its setup, as the checkout will unset the core.worktree setting such
that following log will be run in a bare repository.
This patch covers all commands that are in the unpack machinery, i.e.
checkout, read-tree, reset. A follow up patch will address
"git submodule deinit", which will also make use of the new function
submodule_unset_core_worktree(), which is why we expose it in this patch.

When fetching with recursing into submodules, the fetch logic inspects
the superproject which submodules actually need to be fetched. This is
tricky for submodules that were renamed in the fetched range of commits.
This was implemented in c68f837576 (implement fetching of moved
submodules, 2017-10-16), and this patch fixes a mistake in the logic
there.
When the warning is printed, the `name` might be NULL as
default_name_or_path can return NULL, so fix the warning to use the path
as obtained from the diff machinery, as that is not NULL.
While at it, make sure we only attempt to load the submodule if a git
directory of the submodule is found as default_name_or_path will return
NULL in case the git directory cannot be found. Note that passing NULL
to submodule_from_name is just a semantic error, as submodule_from_name
accepts NULL as a value, but then the return value is not the submodule
that was asked for, but some arbitrary other submodule. (Cf. 'config_from'
in submodule-config.c: "If any parameter except the cache is a NULL
pointer just return the first submodule. Can be used to check whether
there are any submodules parsed.")

In a later patch we want to improve submodule merging by using the output()
function in merge-recursive.c for submodule merges to deliver a consistent
UI to users.
To do so we could either make the output() function globally available
so we can use it in submodule.c#merge_submodule(), or we could integrate
the submodule merging into the merging code. Choose the later as we
generally want to move submodules closer into the core.
Therefore we move any function related to merging submodules
(merge_submodule(), find_first_merges() and print_commit) to
merge-recursive.c. We'll keep add_submodule_odb() in submodule.c as it
is used by other submodule functions. While at it, add a TODO note that
we do not really like the function add_submodule_odb().

connect_work_tree_and_git_dir is used to connect a submodule worktree with
its git directory and vice versa after events that require a reconnection
such as moving around the working tree. As submodules can have nested
submodules themselves, we'd also want to fix the nested submodules when
asked to. Add an option to recurse into the nested submodules and connect
them as well.
As submodules are identified by their name (which determines their git
directory in relation to their superproject's git directory) internally
and by their path in the working tree of the superproject, we need to
make sure that the mapping of name <-> path is kept intact. We can do
that in the git-mv command by writing out the gitmodules file first
and then forcing a reload of the submodule config machinery.

We store the changed submodules paths to calculate which submodule needs
fetching. This does not work for moved submodules since their paths do
not stay the same in case of a moved submodules. In case of new
submodules we do not have a path in the current checkout, since they
just appeared in this fetch.
It is more general to collect the submodule names for changes instead of
their paths to include the above cases. If we do not have a
configuration for a gitlink we rely on constructing a default name from
the path if a git repository can be found at its path. We skip
non-configured gitlinks whose default name collides with a configured
one.
With the change described above we implement 'on-demand' fetching of
