Since this header showed up in some places besides just #include
statements, update/clean-up/remove those other places as well.
Note that compat/fsmonitor/fsm-path-utils-darwin.c previously got
away with violating the rule that all files must start with an include
of git-compat-util.h (or a short-list of alternate headers that happen
to include it first). This change exposed the violation and caused it
to stop building correctly; fix it by having it include
git-compat-util.h first, as per policy.

hash.h depends upon and includes repository.h, due to the definition and
use of the_hash_algo (defined as the_repository->hash_algo). However,
most headers trying to include hash.h are only interested in the layout
of the structs like object_id. Move the parts of hash.h that do not
depend upon repository.h into a new file hash-ll.h (the "low level"
parts of hash.h), and adjust other files to use this new header where
the convenience inline functions aren't needed.
This allows hash.h and object.h to be fairly small, minimal headers. It
also exposes a lot of hidden dependencies on both path.h (which was
brought in by repository.h) and repository.h (which was previously
implicitly brought in by object.h), so also adjust other files to be
more explicit about what they depend upon.

Fix a logic error in 4950b2a2b5c (for-each-repo: run subcommands on
configured repos, 2020-09-11). Due to assuming that elements returned
from the repo_config_get_value_multi() call wouldn't be "NULL" we'd
conflate the <path> and <command> part of the argument list when
running commands.
As noted in the preceding commit the fix is to move to a safer
"*_string_multi()" version of the *_multi() API. This change is
separated from the rest because those all segfaulted. In this change
we ended up with different behavior.
When using the "--config=<config>" form we take each element of the
list as a path to a repository. E.g. with a configuration like:
[repo] list = /some/repo
We would, with this command:
git for-each-repo --config=repo.list status builtin
Run a "git status" in /some/repo, as:
git -C /some/repo status builtin
I.e. ask "status" to report on the "builtin" directory. But since a
configuration such as this would result in a "struct string_list *"
with one element, whose "string" member is "NULL":
[repo] list
We would, when constructing our command-line in
"builtin/for-each-repo.c"...
strvec_pushl(&child.args, "-C", path, NULL);
for (i = 0; i < argc; i++)
strvec_push(&child.args, argv[i]);
...have that "path" be "NULL", and as strvec_pushl() stops when it
sees NULL we'd end with the first "argv" element as the argument to
the "-C" option, e.g.:
git -C status builtin
I.e. we'd run the command "builtin" in the "status" directory.
In another context this might be an interesting security
vulnerability, but I think that this amounts to a nothingburger on
that front.
A hypothetical attacker would need to be able to write config for the
victim to run, if they're able to do that there's more interesting
attack vectors. See the "safe.directory" facility added in
8d1a7448206 (setup.c: create `safe.bareRepository`, 2022-07-14).
An even more unlikely possibility would be an attacker able to
generate the config used for "for-each-repo --config=<key>", but
nothing else (e.g. an automated system producing that list).
Even in that case the attack vector is limited to the user running
commands whose name matches a directory that's interesting to the
attacker (e.g. a "log" directory in a repository). The second
argument (if any) of the command is likely to make git die without
doing anything interesting (e.g. "-p" to "log", there being no "-p"
built-in command to run).

As noted in 6c62f015520 (for-each-repo: do nothing on empty config,
2021-01-08) this command wants to ignore a non-existing config key,
but let's not conflate that with bad config.
Before this, all these added tests would pass with an exit code of 0.
We could preserve the comment added in 6c62f015520, but now that we're
directly using the documented repo_config_get_value_multi() value it's
just narrating something that should be obvious from the API use, so
let's drop it.

Have the "git_configset_get_value_multi()" function and its siblings
return an "int" and populate a "**dest" parameter like every other
git_configset_get_*()" in the API.
As we'll take advantage of in subsequent commits, this fixes a blind
spot in the API where it wasn't possible to tell whether a list was
empty from whether a config key existed. For now we don't make use of
those new return values, but faithfully convert existing API users.
Most of this is straightforward, commentary on cases that stand out:
- To ensure that we'll properly use the return values of this function
in the future we're using the "RESULT_MUST_BE_USED" macro introduced
in [1].
As git_die_config() now has to handle this return value let's have
it BUG() if it can't find the config entry. As tested for in a
preceding commit we can rely on getting the config list in
git_die_config().
- The loops after getting the "list" value in "builtin/gc.c" could
also make use of "unsorted_string_list_has_string()" instead of using
that loop, but let's leave that for now.
- In "versioncmp.c" we now use the return value of the functions,
instead of checking if the lists are still non-NULL.

Dozens of files made use of gettext functions, without explicitly
including gettext.h. This made it more difficult to find which files
could remove a dependence on cache.h. Make C files explicitly include
gettext.h if they are using it.
However, while compat/fsmonitor/fsm-ipc-darwin.c should also gain an
include of gettext.h, it was left out to avoid conflicting with an
in-flight topic.

Add the "[--]" for those cases where the *.txt and -h were
inconsistent, or where we incorrectly stated in one but not the other
that the "--" was mandatory.
In the case of "rev-list" both sides were wrong, as we we don't
require one or more paths if "--" is used, e.g. this is OK:
git rev-list HEAD --
That part of this change is not a "doc txt & -h consistency" change,
as we're changing both versions, doing so here makes both sides
consistent.

Fix various inconsistencies between command SYNOPSIS and the
corresponding -h output where our translatable labels didn't match
up.
In some cases we need to adjust the prose that follows the SYNOPSIS
accordingly, as it refers back to the changed label.

cmd_for_each_repo() copies argv into args (a strvec), which is later
passed into run_command_on_repo(), which in turn copies that strvec onto
the end of child.args. The initial copy is unnecessary (we never modify
args). We therefore choose to just pass argv directly into
run_command_on_repo(), which lets us avoid the copy and fixes the leak.

'git for-each-repo --config=X' should return success without calling any
subcommands when the config key 'X' has no value. The current
implementation instead segfaults.
A user could run into this issue if they used 'git maintenance start' to
initialize their cron schedule using 'git for-each-repo
--config=maintenance.repo ...' but then using 'git maintenance
unregister' to remove the config option. (Note: 'git maintenance stop'
would remove the config _and_ remove the cron schedule.)
Add a simple test to ensure this works. Use 'git help --no-such-option'
as the potential subcommand to ensure that we will hit a failure if the
subcommand is ever run.

It can be helpful to store a list of repositories in global or system
config and then iterate Git commands on that list. Create a new builtin
that makes this process simple for experts. We will use this builtin to
run scheduled maintenance on all configured repositories in a future
change.
The test is very simple, but does highlight that the "--" argument is
optional.
