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.

For the functions defined in read-cache.c, move their declarations from
cache.h to a new header, read-cache-ll.h. Also move some related inline
functions from cache.h to read-cache.h. The purpose of the
read-cache-ll.h/read-cache.h split is that about 70% of the sites don't
need the inline functions and the extra headers they include.

The function add_files_to_cache() is used by all three of builtin/{add,
checkout, commit}.c. That suggests this is common library code, and
should be moved somewhere else, like read-cache.c. However, the
function and its helpers made use of two global variables that made
straight code movement difficult:
* the_index
* include_sparse
The latter was perhaps more problematic since it was only accessible in
builtin/add.c but was still affecting builtin/checkout.c and
builtin/commit.c without this fact being very clear from the code. I'm
not sure if the other two callers would want to add a `--sparse` flag
similar to add.c to get non-default behavior, but exposing this
dependence will help if we ever decide we do want to add such a flag.
Modify add_files_to_cache() and its helpers to accept the necessary
arguments instead of relying on globals.

Much like the parent commit, this commit was prompted by a desire to
move the functions which builtin/init-db.c and builtin/clone.c share out
of the former file and into setup.c. A secondary issue that made it
difficult was the init_shared_repository global variable; replace it
with a simple parameter that is passed to the relevant functions.

This commit was prompted by a desire to move the functions which
builtin/init-db.c and builtin/clone.c share out of the former file and
into setup.c. One issue that made it difficult was the
init_is_bare_repository global variable.
init_is_bare_repository's sole use in life it to cache a value in
init_db(), and then be used in create_default_files(). This is a bit
odd since init_db() directly calls create_default_files(), and is the
only caller of that function. Convert the global to a simple function
parameter instead.
(Of course, this doesn't fix the fact that this value is then ignored by
create_default_files(), as noted in a big TODO comment in that function,
but it at least includes no behavioral change other than getting rid of
a very questionable global variable.)

The comments in create_default_files() talks about reading config from
the config file in the specified `--templates` directory, which leads to
the question of whether core.bare could be set in such a config file and
thus whether the code is doing the right thing. It turns out, that it
doesn't; it unconditionally ignores core.bare in the config file in any
--templates directory. It is not clear to me that fixing it can be done
within this function; it seems to occur too late:
* create_default_files() is called by init_db()
* init_db() is called by both builtin/{clone.c,init-db.c}
* both callers of init_db() call set_git_work_tree() before init_db()
and in order to actual affect whether a repository is bear, we'd need to
somewhere reset these values, not just the is_bare_repository_cfg
setting.
I do not want to open this can of worms at this time; I'm trying to
clean up some headers, for which I need to move some functions, for
which I need to clean up some globals, and that's far enough down the
rabbit hole. So, simply document the issue with a careful TODO comment
and a few testcases.

The value of config.worktree is per-repository, but has been kept
in a singleton global variable per process. This has been OK as
most Git operations interacted with a single repository at a time,

the pathspec allows it

Move 'repository_format_worktree_config' out of the global scope and into
the 'repository' struct. This change is similar to how
'repository_format_partial_clone' was moved in ebaf3bcf1ae (repository: move
global r_f_p_c to repo struct, 2021-06-17), adding it to the 'repository'
struct and updating 'setup.c' & 'repository.c' functions to assign the value
appropriately.
The primary goal of this change is to be able to load the worktree config of
a submodule depending on whether that submodule - not its superproject - has
'extensions.worktreeConfig' enabled. To ensure 'do_git_config_sequence()'
has access to the newly repo-scoped configuration, add a 'struct repository'
argument to 'do_git_config_sequence()' and pass it the 'repo' value from
'config_with_options()'.
Finally, add/update tests in 't3007-ls-files-recurse-submodules.sh' to
verify 'extensions.worktreeConfig' is read an used independently by
superprojects and submodules.

Add a 'struct repository' argument to 'config_with_options()' and remove the
'repo' field from 'struct git_config_source'.
A 'struct repository' instance was originally added to the config source in
e3e8bf046e9 (submodule-config: pass repo upon blob config read, 2021-08-16)
to improve how submodule blob config content was accessed. At the time, this
was the only use for a 'repository' instance, so it was naturally added only
where it was needed: to 'struct git_config_source'. However, in upcoming
patches, 'config_with_options()' will need the repository instance to access
extension information (regardless of whether a 'config_source' exists). To
make the 'struct repository' instance more easily accessible, move it into
the function's arguments.
Update all callers of 'config_with_options()' to pass the appropriate 'repo'
value:
* in 'builtin/config.c', use 'the_repository'
* in 'submodule--config.c', use the 'repo' arg in 'config_from_gitmodules()'
* in 'read_[very_]early_config()' & 'read_protected_config()', set 'repo' to
NULL (repository instances aren't available there)
* in 'populate_remote_urls()', use the repo instance that has been added to
the 'struct config_include_data'
* in 'repo_read_config()', use the given 'repo' arg
Finally, note that this patch eliminates the fallback to 'the_repository'
that previously existed for the 'config_source' repo instance if it was
NULL. The fallback is no longer necessary, as the 'repo' is set explicitly
in all cases where it is needed.

In e0a862fdaf (submodule helper: convert relative URL to absolute URL if
needed, 2018-10-16), `prepare_to_clone_next_submodule()` lost the
ability to handle URL-less submodules, due to a change from:
if (repo_get_config_string_const(the_repostiory, sb.buf, &url))
url = sub->url;
to
if (repo_get_config_string_const(the_repostiory, sb.buf, &url)) {
if (starts_with_dot_slash(sub->url) ||
starts_with_dot_dot_slash(sub->url)) {
/* ... */
}
}
, which will segfault when `sub->url` is NULL, since both
`starts_with_dot_slash()` does not guard its arguments as non-NULL.
Guard the checks to both of the above functions by first checking
whether `sub->url` is non-NULL. There is no need to check whether `sub`
itself is NULL, since we already perform this check earlier in
`prepare_to_clone_next_submodule()`.
By adding a NULL-ness check on `sub->url`, we'll fall into the 'else'
branch, setting `url` to `sub->url` (which is NULL). Before attempting
to invoke `git submodule--helper clone`, check whether `url` is NULL,
and die() if it is.

"git ls-files --format" can be used to format the output of
multiple file entries in the index, while "git ls-tree --format"
can be used to format the contents of a tree object. However,
the current set of %(objecttype), "(objectsize)", and
"%(objectsize:padded)" atoms supported by "git ls-files --format"
is a subset of what is available in "git ls-tree --format".
Users sometimes need to establish a unified view between the index
and tree, which can help with comparison or conversion between the two.
Therefore, this patch adds the missing atoms to "git ls-files --format".
"%(objecttype)" can be used to retrieve the object type corresponding
to a file in the index, "(objectsize)" can be used to retrieve the
object size corresponding to a file in the index, and "%(objectsize:padded)"
is the same as "(objectsize)", except with padded format.

When we are showing multiple patches with format-patch, we have to
repeatedly overwrite the rev.message_id field. We take care to avoid
leaking the old value by either freeing it, or adding it to
ref_message_ids, a string list of ids to reference in subsequent
messages.
But unfortunately we do leak the value via that string list. We try
to clear the string list, courtesy of 89f45cf4eb (format-patch: don't
leak "extra_headers" or "ref_message_ids", 2022-04-13). But since it was
initialized as "nodup", the string list doesn't realize it owns the
strings, and it leaks them.
We have two options here:
1. Continue to init with "nodup", but then tweak the value of
ref_message_ids.strdup_strings just before clearing.
2. Init with "dup", but use "append_nodup" when transferring ownership
of strings to the list. Clearing just works.
I picked the second here, as I think it calls attention to the tricky
part (transferring ownership via the nodup call).
There's one other related fix we have to do, though. We also insert the
result of clean_message_id() into the list. This _sometimes_ allocates
and sometimes does not, depending on whether we have to remove cruft
from the end of the string. Let's teach it to consistently return an
allocated string, so that the caller knows it must be freed.
There's no new test here, as the leak can already be seen in t4014.44 (as
well as others in that script). We can't mark all of t4014 as leak-free,
though, as there are other unrelated leaks that it triggers.

We may allocate a message-id string via gen_message_id(), but we never
free it, causing a small leak. This can be demonstrated by running t9001
with a leak-checking build. The offending test is the one touched by
3ece9bf0f9 (send-email: clear the $message_id after validation,
2023-05-17), but the leak is much older than that. The test was simply
unlucky enough to trigger the leaking code path for the first time.
We can fix this by freeing the string at the end of the function. We can
also re-mark the test script as leak-free, effectively reverting
20bd08aefb (t9001: mark the script as no longer leak checker clean,
2023-05-17).

The index is read in 'cmd_diff_tree' at two points:
1. The first index read was added in fd66bcc31ff (diff-tree: read the
index so attribute checks work in bare repositories, 2017-12-06) to deal
with reading '.gitattributes' content. 77efbb366ab (attr: be careful
about sparse directories, 2021-09-08) established that, in a sparse
index, we do _not_ try to load a '.gitattributes' file from within a
sparse directory.
2. The second index access point is involved in rename detection,
specifically when reading from stdin.This was initially added in
f0c6b2a2fd9 ([PATCH] Optimize diff-tree -[CM]--stdin, 2005-05-27), where
'setup' was set to 'DIFF_SETUP_USE_SIZE_CACHE |DIFF_SETUP_USE_CACHE'.
That assignment was later modified to drop the'DIFF_SETUP_USE_CACHE' in
ff7fe37b053 (diff.c: move read_index() code back to the caller,
2018-08-13).However, 'DIFF_SETUP_USE_SIZE_CACHE' seems to be unused as
of 6e0b8ed6d35 (diff.c: do not use a separate "size cache"., 2007-05-07)
and nothing about 'detect_rename' otherwise indicates index usage.
Hence we can just set the requires-full-index to false for "diff-tree".
Add tests that verify that 'git diff-tree' behaves correctly when the
sparse index is enabled and test to ensure the index is not expanded.
The `p2000` tests demonstrate a ~98% execution time reduction for
'git diff-tree' using a sparse index:
