[PATCH 3/6] builtin/submodule--helper: factor out submodule updating

[Stefan Beller]

Separate the command line parsing from the actual execution of the command
within the repository. For now there is not a lot of execution as
most of it is still in git-submodule.sh.

[PATCH 1/6] git-submodule.sh: align error reporting for update mode to use path

[Stefan Beller]

All other error messages in cmd_update are reporting the submodule based
on its path, so let's do that for invalid update modes, too.

[PATCH 2/6] git-submodule.sh: rename unused variables

[Stefan Beller]

The 'mode' variable is not used in cmd_update for its original purpose,
rename it to 'dummy' as it only serves the purpose to abort quickly
documenting this knowledge.

The variable 'stage' is also not used any more in cmd_update, so remove it.

This went unnoticed as first each function used the commonly used
submodule listing, which was converted in 74703a1e4df (submodule: rewrite
`module_list` shell function in C, 2015-09-02). When cmd_update was
using its own function starting in 48308681b07 (git submodule update:
have a dedicated helper for cloning, 2016-02-29), its removal was missed.

A later patch in this series also touches the communication between
the submodule helper and git-submodule.sh, but let's have this as
a preparatory patch, as it eases the next patch, which stores the
raw data instead of the line printed for this communication.

[PATCH 4/6] builtin/submodule--helper: store update_clone information in a struct

[Stefan Beller]

The information that is printed for update_submodules in
'submodule--helper update-clone' and consumed by 'git submodule update'
is stored as a string per submodule. This made sense at the time of
48308681b07 (git submodule update: have a dedicated helper for cloning,
2016-02-29), but as we want to migrate the rest of the submodule update
into C, we're better off having access to the raw information in a helper
struct.

[PATCH 6/6] submodule--helper: introduce new update-module-mode helper

[Stefan Beller]

This chews off a bit of the shell part of the update command in
git-submodule.sh. When writing the C code, keep in mind that the
submodule--helper part will go away eventually and we want to have
a C function that is able to determine the submodule update strategy,
it as a nicety, make determine_submodule_update_strategy accessible
for arbitrary repositories.

Thanks.  

This time not from GGG?  I don't particularly care which direction
patches come from, though ;-)

GGG = GitGitGadget?
I have yet to try out that tool, I am still stuck on git-send-email.
(old habits die hard)

It is even based off your branch (with all your sign offs).

I just cut down aggressively on the range diff (and short stat),
as I want to highlight the important part.
