In C it isn't required to specify that all members of a struct are
zero'd out to 0, NULL or '\0', just providing a "{ 0 }" will
accomplish that.
Let's also change code that provided N zero'd fields to just
provide one, and change e.g. "{ NULL }" to "{ 0 }" for
consistency. I.e. even if the first member is a pointer let's use "0"
instead of "NULL". The point of using "0" consistently is to pick one,
and to not have the reader wonder why we're not using the same pattern
everywhere.

We currently store each submodule gitdir in ".git/modules/<name>", but
this has problems with some submodule naming schemes, as described in a
comment in submodule_name_to_gitdir() in this patch.
Extract the determination of the location of a submodule's gitdir into
its own function submodule_name_to_gitdir(). For now, the problem
remains unsolved, but this puts us in a better position for finding a
solution.
This was motivated, at $DAYJOB, by a part of Android's repo hierarchy
[1]. In particular, there is a repo "build", and several repos of the
form "build/<name>".
This is based on earlier work by Brandon Williams [2].

We check that git.html exists, regardless of the page the user wants to open.
Checking whether the requested page exists instead gives us a smoother user
experience in two use cases:
1) The requested page doesn't exist
When calling a git command and there is an error, most users reasonably expect
git to produce an error message on the standard error stream, but in this case
we pass the filepath to git web--browse which passes it on to a browser (or a
helper program like xdg-open or start that should in turn open a browser)
without any error and many GUI based browsers or helpers won't output such a
message onto the standard error stream.
Especially the helper programs tend to show the corresponding error message in
a message box and wait for user input before exiting. This leaves users in
interactive console sessions without an error message in their console,
without a console prompt and without the help page they expected.
2) git.html is missing for some reason, but the user asked for some other page
We currently refuse to show any local html help page when we can't find
git.html. Even if the requested help page exists. If we check for the requested
page instead, we can show the user all available pages and only error out on
those that don't exist.

As was noted in 1a85b49b87 (parse-options: make OPT_ARGUMENT() more
useful, 2019-03-14) there's only ever been one user of the
OPT_ARGUMENT(), that user was added in 20de316e33 (difftool: allow
running outside Git worktrees with --no-index, 2019-03-14).
The OPT_ARGUMENT() feature itself was added way back in
580d5bffde (parse-options: new option type to treat an option-like
parameter as an argument., 2008-03-02), but as discussed in
1a85b49b87 wasn't used until 20de316e33 in 2019.
Now that the preceding commit has migrated this code over to using
"struct strvec" to manage the "args" member of a "struct
child_process", we can just use that directly instead of relying on
OPT_ARGUMENT.
This has a minor change in behavior in that if we'll pass --no-index
we'll now always pass it as the first argument, before we'd pass it in
whatever position the caller did. Preserving this was the real value
of OPT_ARGUMENT(), but as it turns out we didn't need that either. We
can always inject it as the first argument, the other end will parse
it just the same.
Note that we cannot remove the "out" and "cpidx" members of "struct
parse_opt_ctx_t" added in 580d5bffde, while they were introduced with
OPT_ARGUMENT() we since used them for other things.

Change the run_file_diff() function to use the run_command() API
directly, instead of invoking the run_command_v_opt_cd_env() wrapper.
This allows it, like run_dir_diff(), to use the "args" from "struct

cmd_difftool(). This will be used in the subsequent commit to get rid
of OPT_ARGUMENT() from cmd_difftool().

sets up a child argv starting with "diff" and some hard-coded options
(depending on which mode we're using). Let's extract that logic into the

When the launchctl_boot_plist() function was added in
a16eb6b1ff (maintenance: skip bootout/bootstrap when plist is
registered, 2021-08-24), an unused call to launchctl_get_uid() was
added along with it. That call appears to have been copy/pasted from
launchctl_boot_plist().
Since we can remove that, we can also get rid of the "result"
variable, whose only purpose was allow for the free() between its
assignment and the return. That pattern also appears to have been
copy/pasted from launchctl_boot_plist().
As the patch shows the returned value from launchctl_get_uid() wasn't
used at all in this function. The launchctl_get_uid() function itself
just calls xstrfmt() and getuid(), neither of which have any subtle
global side-effects, so this removal is safe.

In preceding commits the race of renaming .idx files in place before
.rev files and other auxiliary files was fixed in pack-write.c's
finish_tmp_packfile(), builtin/repack.c's "struct exts", and
builtin/index-pack.c's final(). As noted in the change to pack-write.c
we left in place the issue of writing *.bitmap files after the *.idx,
let's fix that issue.
See 7cc8f97108 (pack-objects: implement bitmap writing, 2013-12-21)
for commentary at the time when *.bitmap was implemented about how
those files are written out, nothing in that commit contradicts what's
being done here.
Note that this commit and preceding ones only close any race condition
with *.idx files being written before their auxiliary files if we're
optimistic about our lack of fsync()-ing in this are not tripping us
over. See the thread at [1] for a rabbit hole of various discussions
about filesystem races in the face of doing and not doing fsync() (and
if doing fsync(), not doing it properly).
We may want to fsync the containing directory once after renaming the
*.idx file into place, but that is outside the scope of this series.

Since the only other caller of finish_tmp_packfile() was in

provide a thin wrapper for the old function as a static function in that
file. If other callers end up needing the simpler version it could be
