5579f44d2f treewide: remove unnecessary cache.h inclusion
Several files were including cache.h solely to get other headers, such
as trace.h and trace2.h.  Since the last few commits have modified
files to make these dependencies more explicit, the inclusion of cache.h
is no longer needed in several cases.  Remove it.

74ea5c9574 treewide: be explicit about dependence on trace.h & trace2.h
Dozens of files made use of trace and trace2 functions, without
explicitly including trace.h or trace2.h.  This made it more difficult
to find which files could remove a dependence on cache.h.  Make C files
explicitly include trace.h or trace2.h if they are using them.

a64acf7298 treewide: remove unnecessary includes of cache.h
The last several commits were geared at replacing the include of cache.h
in strbuf.c with an include of git-compat-util.h.  Unfortunately, I had
to drop a patch moving some functions from cache.h to object-name.h, due
to excessive conflicts with other in-flight topics.

However, even without that patch, the series of patches so far allows us
to modify a number of C files to replace an include of cache.h with
git-compat-util.h.  Do that to reduce our dependencies.

(If we could have kept our object-name.h patch in this series, it would
have also let us reduce the includes in checkout.c and fmt-merge-msg.c
in addition to strbuf.c).

Just to ensure that nothing else was bringing in cache.h, all of the
affected files have been checked to ensure that
    gcc -E -I. $SOURCE_FILE | grep '"cache.h"'
found no hits and that
    make DEVELOPER=1 ${OBJECT_FILE_FOR_SOURCE_FILE}
successfully compiles without warnings.

a6dc3d364c treewide: remove unnecessary cache.h inclusion from a few headers
Ever since a64215b6cd ("object.h: stop depending on cache.h; make
cache.h depend on object.h", 2023-02-24), we have a few headers that
could have replaced their include of cache.h with an include of
object.h.  Make that change now.

Some C files had to start including cache.h after this change (or some
smaller header it had brought in), because the C files were depending
on things from cache.h but were only formerly implicitly getting
cache.h through one of these headers being modified in this patch.

7ce4088ab7 parse-options: consistently allocate memory in fix_filename()
When handling OPT_FILENAME(), we have to stick the "prefix" (if any) in
front of the filename to make up for the fact that Git has chdir()'d to
the top of the repository. We can do this with prefix_filename(), but
there are a few special cases we handle ourselves.

Unfortunately the memory allocation is inconsistent here; if we do make
it to prefix_filename(), we'll allocate a string which the caller must
free to avoid a leak. But if we hit our special cases, we'll return the
string as-is, and a caller which tries to free it will crash. So there's
no way to win.

Let's consistently allocate, so that callers can do the right thing.

There are now three cases to care about in the function (and hence a
three-armed if/else):

  1. we got a NULL input (and should leave it as NULL, though arguably
     this is the sign of a bug; let's keep the status quo for now and we
     can pick at that scab later)

  2. we hit a special case that means we leave the name intact; we
     should duplicate the string. This includes our special "-"
     matching. Prior to this patch, it also included empty prefixes and
     absolute filenames. But we can observe that prefix_filename()
     already handles these, so we don't need to detect them.

  3. everything else goes to prefix_filename()

I've dropped the "const" from the "char **file" parameter to indicate
that we're allocating, though in practice it's not really important.
This is all being shuffled through a void pointer via opt->value before
it hits code which ever looks at the string. And it's even a bit weird,
because we are really taking _in_ a const string and using the same
out-parameter for a non-const string. A better function signature would
be:

  static char *fix_filename(const char *prefix, const char *file);

but that would mean the caller dereferences the double-pointer (and the
NULL check is currently handled inside this function). So I took the
path of least-change here.

Note that we have to fix several callers in this commit, too, or we'll
break the leak-checking tests. These are "new" leaks in the sense that
they are now triggered by the test suite, but these spots have always
been leaky when Git is run in a subdirectory of the repository. I fixed
all of the cases that trigger with GIT_TEST_PASSING_SANITIZE_LEAK. There
may be others in scripts that have other leaks, but we can fix them
later along with those other leaks (and again, you _couldn't_ fix them
before this patch, so this is the necessary first step).

a64215b6cd object.h: stop depending on cache.h; make cache.h depend on object.h
Things should be able to depend on object.h without pulling in all of
cache.h.  Move an enum to allow this.

Note that a couple files previously depended on things brought in
through cache.h indirectly (revision.h -> commit.h -> object.h ->
cache.h).  As such, this change requires making existing dependencies
more explicit in half a dozen files.  The inclusion of strbuf.h in
some headers if of particular note: these headers directly embedded a
strbuf in some new structs, meaning they should have been including
strbuf.h all along but were indirectly getting the necessary
definitions.

41227cb138 hash.h: move some oid-related declarations from cache.h
These defines and enum are all oid-related and as such seem to make
more sense being included in hash.h.  Further, moving them there
allows us to remove some includes of cache.h in other files.

The change to line-log.h might look unrelated, but line-log.h includes
diffcore.h, which previously included cache.h, which included the
kitchen sink.  Since this patch makes diffcore.h no longer include
cache.h, the compiler complains about the 'struct string_list *'
function parameter.  Add a forward declaration for struct string_list to
address this.

e00e56a7df dir-iterator: drop unused DIR_ITERATOR_FOLLOW_SYMLINKS
The `FOLLOW_SYMLINKS` flag was added to the dir-iterator API in
fa1da7d2ee (dir-iterator: add flags parameter to dir_iterator_begin,
2019-07-10) in order to follow symbolic links while traversing through a
directory.

`FOLLOW_SYMLINKS` gained its first caller in ff7ccc8c9a (clone: use
dir-iterator to avoid explicit dir traversal, 2019-07-10), but it was
subsequently removed in 6f054f9fb3 (builtin/clone.c: disallow `--local`
clones with symlinks, 2022-07-28).

Since then, we've held on to the code for `DIR_ITERATOR_FOLLOW_SYMLINKS`
in the name of making minimally invasive changes during a security
embargo.

In fact, we even changed the dir-iterator API in bffc762f87
(dir-iterator: prevent top-level symlinks without FOLLOW_SYMLINKS,
2023-01-24) without having any non-test callers of that flag.

Now that we're past those security embargo(s), let's finalize our
cleanup of the `DIR_ITERATOR_FOLLOW_SYMLINKS` code and remove its
implementation since there are no remaining callers.

Since [1] there has been no reason for keeping "git env--helper" a
built-in. The reason it was a built-in to begin with was to support
the GIT_TEST_GETTEXT_POISON mode removed in that commit. I.e. unlike
the rest of "test-tool" it would potentially be called by the
installed git via "git-sh-i18n.sh".

As none of that applies since [1] we should stop carrying this
technical debt, and move it to t/helper/*. As this mostly move-only
change shows this has the nice bonus that we'll stop wasting time
translating the internal-only strings it emits.

Even though this was a built-in, it was intentionally never
documented, see its introduction in [2]. It never saw use outside of
the test suite, except for the "GIT_TEST_GETTEXT_POISON" use-case
noted above.

d4e241a145 test-bundle-uri: drop unused variables
Commit 70b9c10373 (bundle-uri client: add helper for testing server,
2022-12-22) added a cmd_ls_remote() function which contains "uploadpack"
and "server_options" variables. Neither of these variables is ever
modified after being initialized, so the code to handle non-NULL and
non-empty values is impossible to reach.

While in theory we might add command-line parsing to set these, let's
drop the dead code for now in the name of cleanliness. It's easy enough
to add it back later if need be.

Noticed by Coverity.

ebc3947955 bundle-uri: allow relative URLs in bundle lists
Bundle providers may want to distribute that data across multiple CDNs.
This might require a change in the base URI, all the way to the domain
name. If all bundles require an absolute URI in their 'uri' value, then
every push to a CDN would require altering the table of contents to
match the expected domain and exact location within it.

Allow a bundle list to specify a relative URI for the bundles. This URI
is based on where the client received the bundle list. For a list
provided in the 'bundle-uri' protocol v2 command, the Git remote URI is
the base URI. Otherwise, the bundle list was provided from an HTTP URI
not using the Git protocol, and that URI is the base URI. This allows
easier distribution of bundle data.

70b9c10373 bundle-uri client: add helper for testing server
Add a 'test-tool bundle-uri ls-remote' command. This is a thin wrapper
for issuing protocol v2 "bundle-uri" commands to a server, and to the
parsing routines in bundle-uri.c.

In the "git clone" case we'll have already done the handshake(),
but not here. Add an extra case to check for this handshake in
get_bundle_uri() for ease of use for future callers.

b6046abc0c built-ins & libs & helpers: add/move destructors, fix leaks
Fix various leaks in built-ins, libraries and a test helper here we
were missing a call to strbuf_release(), string_list_clear() etc, or
were calling them after a potential "return".

Comments on individual changes:

- builtin/checkout.c: Fix a memory leak that was introduced in [1]. A
  sibling leak introduced in [2] was recently fixed in [3]. As with [3]
  we should be using the wt_status_state_free_buffers() API introduced
  in [4].

- builtin/repack.c: Fix a leak that's been here since this use of
  "strbuf_release()" was added in a1bbc6c017 (repack: rewrite the shell
  script in C, 2013-09-15). We don't use the variable for anything
  except this loop, so we can instead free it right afterwards.

- builtin/rev-parse: Fix a leak that's been here since this code was
  added in 21d4783538 (Add a parseopt mode to git-rev-parse to bring
  parse-options to shell scripts., 2007-11-04).

- builtin/stash.c: Fix a couple of leaks that have been here since
  this code was added in d4788af875 (stash: convert create to builtin,
  2019-02-25), we strbuf_release()'d only some of the "struct strbuf" we
  allocated earlier in the function, let's release all of them.

- ref-filter.c: Fix a leak in 482c119186 (gpg-interface: improve
  interface for parsing tags, 2021-02-11), we don't use the "payload"
  variable that we ask parse_signature() to populate for us, so let's
  free it.

- t/helper/test-fake-ssh.c: Fix a leak that's been here since this
  code was added in 3064d5a38c (mingw: fix t5601-clone.sh,
  2016-01-27). Let's free the "struct strbuf" as soon as we don't need
  it anymore.

1. c45f0f525d (switch: reject if some operation is in progress,
   2019-03-29)
2. 2708ce62d2 (branch: sort detached HEAD based on a flag,
   2021-01-07)
3. abcac2e19f (ref-filter.c: fix a leak in get_head_description,
   2022-09-25)
4. 962dd7ebc3 (wt-status: introduce wt_status_state_free_buffers(),
   2020-09-27).
