0f2dc722dd refs: convert resolve_refdup and refs_resolve_refdup to struct object_id
All of the callers already pass the hash member of struct object_id, so
update them to pass a pointer to the struct directly,

This transformation was done with an update to declaration and

a9f8a37584 submodule: port submodule subcommand 'status' from shell to C
This aims to make git-submodule 'status' a built-in. Hence, the function
cmd_status() is ported from shell to C. This is done by introducing
four functions: module_status(), submodule_status_cb(),
submodule_status() and print_status().

The function module_status() acts as the front-end of the subcommand.
It parses subcommand's options and then calls the function
module_list_compute() for computing the list of submodules. Then
this functions calls for_each_listed_submodule() looping through the
list obtained.

Then for_each_listed_submodule() calls submodule_status_cb() for each of
the submodule in its list. The function submodule_status_cb() calls
submodule_status() after passing appropriate arguments to the funciton.
Function submodule_status() is responsible for generating the status
each submodule it is called for, and then calls print_status().

Finally, the function print_status() handles the printing of submodule's
status.

Function set_name_rev() is also ported from git-submodule to the
submodule--helper builtin function compute_rev_name(), which now
generates the value of the revision name as required.

1cf01a34ea consistently use "fallthrough" comments in switches
Gcc 7 adds -Wimplicit-fallthrough, which can warn when a
switch case falls through to the next case. The general idea
is that the compiler can't tell if this was intentional or
not, so you should annotate any intentional fall-throughs as
such, leaving it to complain about any unannotated ones.

There's a GNU __attribute__ which can be used for
annotation, but of course we'd have to #ifdef it away on
non-gcc compilers. Gcc will also recognize
specially-formatted comments, which matches our current
practice. Let's extend that practice to all of the
unannotated sites (which I did look over and verify that
they were behaving as intended).

Ideally in each case we'd actually give some reasons in the
comment about why we're falling through, or what we're
falling through to. And gcc does support that with
-Wimplicit-fallthrough=2, which relaxes the comment pattern
matching to anything that contains "fallthrough" (or a
variety of spelling variants). However, this isn't the
default for -Wimplicit-fallthrough, nor for -Wextra. In the
name of simplicity, it's probably better for us to support
the default level, which requires "fallthrough" to be the
only thing in the comment (modulo some window dressing like
"else" and some punctuation; see the gcc manual for the
complete set of patterns).

This patch suppresses all warnings due to
-Wimplicit-fallthrough. We might eventually want to add that
to the DEVELOPER Makefile knob, but we should probably wait
until gcc 7 is more widely adopted (since earlier versions
will complain about the unknown warning type).

2cc67fe54a submodule: remove submodule_config callback routine
Remove the last remaining caller of 'submodule_config()' as well as the
function itself.

With 'submodule_config()' being removed the submodule-config API can be
a little simpler as callers don't need to worry about whether or not
they need to overlay the repository's config on top of the
submodule-config.  This also makes it more difficult to accidentally
add non-submodule specific configuration to the .gitmodules file.

f20e7c1ea2 submodule: remove submodule.fetchjobs from submodule-config parsing
The '.gitmodules' file should only contain information pertinent to
configuring individual submodules (name to path mapping, URL where to
obtain the submodule, etc.) while other configuration like the number of
jobs to use when fetching submodules should be a part of the
repository's config.

Remove the 'submodule.fetchjobs' configuration option from the general
submodule-config parsing and instead rely on using the
'config_from_gitmodules()' in order to maintain backwards compatibility
with this config being placed in the '.gitmodules' file.

c1e860f1dc run_processes_parallel: change confusing task_cb convention
By declaring the task_cb parameter of type `void **`, the signature of
the get_next_task method suggests that the "task-specific cookie" can be
defined in that method, and the signatures of the start_failure and of
the task_finished methods declare that parameter of type `void *`,
suggesting that those methods are mere users of said cookie.

That convention makes a total lot of sense, because the tasks are pretty
much dead when one of the latter two methods is called: there would be
little use to reset that cookie at that point because nobody would be
able to see the change afterwards.

However, this is not what the code actually does. For all three methods,
it passes the *address* of pp->children[i].data.

As reasoned above, this behavior makes no sense. So let's change the
implementation to adhere to the convention suggested by the signatures.

c7be7201a7 submodule--helper: teach push-check to handle HEAD
In 06bf4ad1d (push: propagate remote and refspec with
--recurse-submodules) push was taught how to propagate a refspec down to
submodules when the '--recurse-submodules' flag is given.  The only refspecs
that are allowed to be propagated are ones which name a ref which exists
in both the superproject and the submodule, with the caveat that 'HEAD'
was disallowed.

This patch teaches push-check (the submodule helper which determines if
a refspec can be propagated to a submodule) to permit propagating 'HEAD'
if and only if the superproject and the submodule both have the same
named branch checked out and the submodule is not in a detached head
state.

1f8d711548 submodule--helper init: set submodule.<name>.active
When initializing a submodule set the submodule.<name>.active config to
true if the module hasn't already been configured to be active by some
other means (e.g. a pathspec set in submodule.active).

3e7eaed016 submodule init: initialize active submodules
Teach `submodule init` to initialize submodules which have been
configured to be active by setting 'submodule.active' with a pathspec.

Now if no path arguments are given and 'submodule.active' is configured,
`init` will initialize all submodules which have been configured to be
active.  If no path arguments are given and 'submodule.active' is not
configured, then `init` will retain the old behavior of initializing all
submodules.

This allows users to record more complex patterns as it saves retyping
them whenever you invoke update.

5c2bd8b77a submodule--helper: add is-active subcommand
The definition of which submodules are of interest by the user
is tied to the configuration submodule.<name>.url; when it is
set to a non-empty string, it is of interest.  We'd want to be
able to later change this definition, but there are many places
that explicitly check this condition in the scripted Porcelain.

Introduce the "is-active" subcommand to "submodule--helper", so
that the exact definition of what submodule is of interest can
be centrally defined (and changed in later steps).  In a few
patches that follow, this helper is used to replace the explicit
checks of the configuration variable in scripts.

d1b3b81aab submodule init: warn about falling back to a local path
When a submodule is initialized, the config variable 'submodule.<name>.url'
is set depending on the value of the same variable in the .gitmodules
file. When the URL indicates to be relative, then the url is computed
relative to its default remote. The default remote cannot be determined
accurately in all cases, such that it falls back to 'origin'.

The 'origin' remote may not exist, though. In that case we give up looking
for a suitable remote and we'll just assume it to be a local relative path.

This can be confusing to users as there is a lot of guessing involved,
which is not obvious to the user.

So in the corner case of assuming a local autoritative truth, warn the
user to lessen the confusion.

This behavior was introduced in 4d6893200 (submodule add: allow relative
repository path even when no url is set, 2011-06-06), which shared the
code with submodule-init and then ported to C in 3604242f08 (submodule:
port init from shell to C, 2016-04-15).

In case of submodule-add, this behavior makes sense in some use cases[1],
however for submodule-init there does not seem to be an immediate obvious
use case to fall back to a local submodule. However there might be, so
warn instead of die here.

While adding the warning, also clarify the behavior of relative URLs in
the documentation.

6e7c14e65c submodule update --init: display correct path from submodule
In the submodule helper we did not correctly handled the display path
for initializing submodules when both the submodule is inside a
subdirectory as well as the command being invoked from a subdirectory
(as viewed from the superproject).

This was broken in 3604242f08, which was written at a time where
there was no super-prefix available, so we abused the --prefix option
for the same purpose and could get only one case right (the call from
within a subdirectory, not the submodule being in a subdirectory).
