By default git submodule update runs a simple checkout on submodules that
are not up-to-date. If the submodules contains modified or untracked
files, the command may exit sanely with an error:
$ git submodule update
error: Your local changes to the following files would be overwritten by
checkout:

Please, commit your changes or stash them before you can switch branches.
Aborting
Unable to checkout '1b69c6e55606b48d3284a3a9efe4b58bfb7e8c9e' in
submodule path 'test1'
In order to reset a whole git submodule tree, a user has to run first 'git
submodule foreach --recursive git checkout -f' and then run 'git submodule
update'.
This patch adds a --force option for the update command (only used for
submodules without --rebase or --merge options). It passes the --force
option to git checkout which will throw away the local changes.

If the commit to be checked out on "git submodule update" has already been
fetched in the submodule there is no need to run "git fetch" again. Since
"git fetch" recently learned recursion (and the new on-demand mode to
fetch commits recorded in the superproject is enabled by default) this
will happen pretty often, thereby making the unconditional fetch during
"git submodule update" unnecessary.
If the commit is not present in the submodule (e.g. the user disabled the
fetch on-demand mode) the fetch will be run as before.

Add two test cases in t7406 to ensure that the --merge/--rebase options
are ignored for "git submodule update" with new modules. These test that
a simple checkout is performed instead.

These tests have been broken since they were introduced in commits
ca2cedb (git-submodule: add support for --rebase., 2009-04-24) and
42b4917 (git-submodule: add support for --merge., 2009-06-03).
'git submodule init' expects the submodules to exist in the index.
In this case, the submodules don't exist and therefore looking for
the submodules will always fail. To make matters worse, git submodule
fails visibly to the user by saying:
error: pathspec 'rebasing' did not match any file(s) known to git.
Did you forget to 'git add'?
but doesn't return an error code. This allows the test to fail silently.
Fix it by adding the submodules first.

'git submodule update --merge' merges the commit referenced by the
superproject into your local branch, instead of checking it out on
a detached HEAD.
As evidenced by the addition of "git submodule update --rebase", it
is useful to provide alternatives to the default 'checkout' behaviour
of "git submodule update". One such alternative is, when updating a
submodule to a new commit, to merge that commit into the current
local branch in that submodule. This is useful in workflows where
you want to update your submodule from its upstream, but you cannot
use --rebase, because you have downstream people working on top of
your submodule branch, and you don't want to disrupt their work.

The addition of "submodule.<name>.rebase" demonstrates the usefulness of
alternatives to the default behaviour of "git submodule update". However,
by naming the config variable "submodule.<name>.rebase", and making it a
boolean choice, we are artificially constraining future git versions that
may want to add _more_ alternatives than just "rebase".
Therefore, while "submodule.<name>.rebase" is not yet in a stable git
release, future-proof it, by changing it from
submodule.<name>.rebase = true/false
to
submodule.<name>.update = rebase/checkout
where "checkout" specifies the default behaviour of "git submodule update"
(checking out the new commit to a detached HEAD), and "rebase" specifies
the --rebase behaviour (where the current local branch in the submodule is
rebase onto the new commit). Thus .update == checkout is equivalent to
.rebase == false, and .update == rebase is equivalent to .rebase == true.
Finally, leaving .update unset is equivalent to leaving .rebase unset.
In future git versions, other alternatives to "git submodule update"
behaviour can be included by adding them to the list of allowable values
for the submodule.<name>.update variable.

'git submodule update --rebase' rebases your local branch on top of what
would have been checked out to a detached HEAD otherwise.
In some cases, detaching the HEAD when updating a submodule complicates
the workflow to commit to this submodule (checkout master, rebase, then
commit). For submodules that require frequent updates but infrequent
(if any) commits, a rebase can be executed directly by the git-submodule
command, ensuring that the submodules stay on their respective branches.
