git: Update to version 2.52.0

- Update from version 2.51.0 to 2.52.0
- Update of rootfile
- Changelog
    2.52.0
	UI, Workflows & Features
	 * The "list" subcommand of "git refs" acts as a front-end for
	   "git for-each-ref".
	 * "git cmd --help-all" now works outside repositories.
	 * "git diff-tree" learned "--max-depth" option.
	 * A new subcommand "git repo" gives users a way to grab various
	   repository characteristics.
	 * A new command "git last-modified" has been added to show the closest
	   ancestor commit that touched each path.
	 * The "git refs exists" command that works like "git show-ref --exists"
	   has been added.
	 * "git repo info" learns the short-hand option "-z" that is the same as
	   "--format=nul", and learns to report the objects format used in the
	   repository.
	 * "core.commentChar=auto" that attempts to dynamically pick a
	   suitable comment character is non-workable, as it is too much
	   trouble to support for little benefit, and is marked as deprecated.
	 * "git send-email" learned to drive "git imap-send" to store already
	   sent e-mails in an IMAP folder.
	 * The "promisor-remote" capability mechanism has been updated to
	   allow the "partialCloneFilter" settings and the "token" value to be
	   communicated from the server side.
	 * Declare that "git init" that is not otherwise configured uses
	   'main' as the initial branch, not 'master', starting Git 3.0.
	 * Keep giving hint about the default initial branch name for users
	   who may be surprised after Git 3.0 switch-over.
	 * The stash.index configuration variable can be set to make "git stash
	   pop/apply" pretend that it was invoked with "--index".
	 * "git fast-import" learned that "--signed-commits=<how>" option that
	   corresponds to that of "git fast-export".
	 * Marking a hunk 'selected' in "git add -p" and then splitting made
	   all the split pieces 'selected'; this has been changed to make them
	   all 'undecided', which gives better end-user experience.
	 * Configuration variables that take a pathname as a value
	   (e.g. blame.ignorerevsfile) can be marked as optional by prefixing
	   ":(optional)" before its value.
	 * Show 'P'ipe command in "git add -p".
	 * "git sparse-checkout" subcommand learned a new "clean" action to
	   prune otherwise unused working-tree files that are outside the
	   areas of interest.
	 * "git fast-import" is taught to handle signed tags, just like it
	   recently learned to handle signed commits, in different ways.
	 * A new configuration variable commitGraph.changedPaths allows to
	   turn "--changed-paths" on by default for "git commit-graph".
	 * "Symlink symref" has been added to the list of things that will
	   disappear at Git 3.0 boundary.
	 * "git maintenance" command learns the "geometric" strategy where it
	   avoids doing maintenance tasks that rebuilds everything from
	   scratch.
	 * "git repo structure", a new command.
	 * The help text and manual page of "git bisect" command have been
	   made consistent with each other.
	Performance, Internal Implementation, Development Support etc.
	 * string_list_split*() family of functions have been extended to
	   simplify common use cases.
	 * Arrays of strbuf is often a wrong data structure to use, and
	   strbuf_split*() family of functions that create them often have
	   better alternatives.  Update several code paths and replace
	   strbuf_split*().
	 * Revision traversal limited with pathspec, like "git log dir/*",
	   used to ignore changed-paths Bloom filter when the pathspec
	   contained wildcards; now they take advantage of the filter when
	   they can.
	 * Doc lint updates to encourage the newer and easier-to-use
	   `synopsis` format, with fixes to a handful of existing uses.
	 * Remove dependency on the_repository and other globals from the
	   commit-graph code, and other changes unrelated to de-globaling.
	 * Discord has been added to the first contribution documentation as
	   another way to ask for help.
	 * Inspired by Ezekiel's recent effort to showcase Rust interface, the
	   hash function implementation used to hash lines have been updated
	   to the one used for ELF symbol lookup by Glibc.
	 * Instead of scanning for the remaining items to see if there are
	   still commits to be explored in the queue, use khash to remember
	   which items are still on the queue (an unacceptable alternative is
	   to reserve one object flag bits).
	 * The bulk-checkin code used to depend on a file-scope static
	   singleton variable, which has been updated to pass an instance
	   throughout the callchain.
	 * The work to build on the bulk-checkin infrastructure to create many
	   objects at once in a transaction and to abstract it into the
	   generic object layer continues.
	 * CodingGuidelines now spells out how bitfields are to be written.
	 * Adjust to the way newer versions of cURL selectively enable tracing
	   options, so that our tests can continue to work.
	 * The clear_alloc_state() API function was not fully clearing the
	   structure for reuse, but since nobody reuses it, replace it with a
	   variant that frees the structure as well, making the callers simpler.
	 * "git range-diff" learned a way to limit the memory consumed by
	   O(N*N) cost matrix.
	 * Some places in the code confused a variable that is *not* a boolean
	   to enable color but is an enum that records what the user requested
	   to do about color.  A couple of bugs of this sort have been fixed,
	   while the code has been cleaned up to prevent similar bugs in the
	   future.
	 * The build procedure based on meson learned a target to only build
	   documentation, similar to "make doc".
	   (merge ff4ec8ded0 ps/meson-build-docs later to maint).
	 * Dip our toes a bit to (optionally) use Rust implemented helper
	   called from our C code.
	 * Documentation for "git log --pretty" options has been updated
	   to make it easier to translate.
	 * Instead of three library archives (one for git, one for reftable,
	   and one for xdiff), roll everything into a single libgit.a archive.
	   This would help later effort to FFI into Rust.
	 * The beginning of SHA1-SHA256 interoperability work.
	 * Build procedure for a few credential helpers (in contrib/) have
	   been updated.
	 * CI improvements to handle the recent Rust integration better.
	 * The code in "git repack" machinery has been cleaned up to prepare
	   for incremental update of midx files.
	 * Two slightly different ways to get at "all the packfiles" in API
	   has been cleaned up.
	 * The code to walk revision graph to compute merge base has been
	   optimized.
	 * AI guidelines has been added to our documentation set.
	 * Contributed credential helpers (obviously in contrib/) now have "cd
	   $there && make install" target.
	 * The "MyFirstContribution" tutorial tells the reader how to send out
	   their patches; the section gained a hint to verify the message
	   reached the mailing list.
	 * The "debug" ref-backend was missing a method implementation, which
	   has been corrected.
	 * Build procedure for Wincred credential helper has been updated.
	 * The build procedure based on meson learned to allow builders to
	   specify the directory to install HTML documents.
	 * Building "git contacts" script (in contrib/) left the resulting
	   file unexecutable, which has been corrected.
	Bug Fixes
	 * During interactive rebase, using 'drop' on a merge commit lead to
	   an error, which was incorrect.
	 * "git refs migrate" to migrate the reflog entries from a refs
	   backend to another had a handful of bugs squashed.
	 * "git remote rename origin upstream" failed to move origin/HEAD to
	   upstream/HEAD when origin/HEAD is unborn and performed other
	   renames extremely inefficiently, which has been corrected.
	   (merge 16c4fa26b9 ps/remote-rename-fix later to maint).
	 * "git describe" has been optimized by using better data structure.
	   (merge 08bb69d70f rs/describe-with-prio-queue later to maint).
	 * "git push" had a code path that led to BUG() but it should have
	   been a die(), as it is a response to a usual but invalid end-user
	   action to attempt pushing an object that does not exist.
	 * Various bugs about rename handling in "ort" merge strategy have
	   been fixed.
	 * "git jump" (in contrib/) fails to parse the diff header correctly
	   when a file has a space in its name, which has been corrected.
	   (merge 621ce9c1c6 gh/git-jump-pathname-with-sp later to maint).
	 * "git diff --no-index" run inside a subdirectory under control of a
	   Git repository operated at the top of the working tree and stripped
	   the prefix from the output, and oddballs like "-" (stdin) did not
	   work correctly because of it.  Correct the set-up by undoing what
	   the set-up sequence did to cwd and prefix.
	 * Various options to "git diff" that makes comparison ignore certain
	   aspects of the differences (like "space changes are ignored",
	   "differences in lines that match these regular expressions are
	   ignored") did not work well with "--name-only" and friends.
	   (merge b55e6d36eb ly/diff-name-only-with-diff-from-content later to maint).
	 * The above caused regressions, which has been corrected.
	 * Documentation for "git rebase" has been updated.
	   (merge 3f7f2b0359 je/doc-rebase later to maint).
	 * The start_delayed_progress() function in the progress eye-candy API
	   did not clear its internal state, making an initial delay value
	   larger than 1 second ineffective, which has been corrected.
	 * The compatObjectFormat extension is used to hide an incomplete
	   feature that is not yet usable for any purpose other than
	   developing the feature further.  Document it as such to discourage
	   its use by mere mortals.
	 * "git log -L..." compared trees of multiple parents with the tree of the
	   merge result in an unnecessarily inefficient way.
	   (merge 0a15bb634c sg/line-log-merge-optim later to maint).
	 * Under a race against another process that is repacking the
	   repository, especially a partially cloned one, "git fetch" may
	   mistakenly think some objects we do have are missing, which has
	   been corrected.
	 * "git fetch" can clobber a symref that is dangling when the
	   remote-tracking HEAD is set to auto update, which has been
	   corrected.
	 * "git describe <blob>" misbehaves and/or crashes in some corner
	   cases, which has been taught to exit with failure gracefully.
	   (merge 7c10e48e81 jk/describe-blob later to maint).
	 * Manual page for "gitk" is updated with the current maintainer's
	   name.
	 * Update the instructions for using GGG in the MyFirstContribution
	   document to say that a GitHub PR could be made against `git/git`
	   instead of `gitgitgadget/git`.
	 * Makefile tried to run multiple "cargo build" which would not work
	   very well; serialize their execution to work around this problem.
	 * "git repack --path-walk" lost objects in some corner cases, which
	   has been corrected.
	 * "git ls-files <pathspec>..." should not necessarily have to expand
	   the index fully if a sparsified directory is excluded by the
	   pathspec; the code is taught to expand the index on demand to avoid
	   this.
	   (merge 681f26bccc ds/ls-files-lazy-unsparse later to maint).
	 * Windows "real-time monitoring" interferes with the execution of
	   tests and affects negatively in both correctness and performance,
	   which has been disabled in Gitlab CI.
	 * A broken or malicious "git fetch" can say that it has the same
	   object for many many times, and the upload-pack serving it can
	   exhaust memory storing them redundantly, which has been corrected.
	 * A corner case bug in "git log -L..." has been corrected.
	 * "git rev-parse --short" and friends failed to disambiguate two
	   objects with object names that share common prefix longer than 32
	   characters, which has been fixed.
	   (merge 8655908b9e jc/longer-disambiguation-fix later to maint).
	 * Some among "git add -p" and friends ignored color.diff and/or
	   color.ui configuration variables, which is an old regression, which
	   has been corrected.
	 * "git subtree" (in contrib/) did not work correctly when splitting
	   squashed subtrees, which has been improved.
	 * Import a newer version of the clar unit testing framework.
	   (merge 93dbb6b3c5 ps/clar-updates later to maint).
	 * "git send-email --compose --reply-to=<address>" used to add
	   duplicated Reply-To: header, which made mailservers unhappy.  This
	   has been corrected.
	   (merge f448f65719 nb/send-email-no-dup-reply-to later to maint).
	 * "git rebase -i" failed to clean-up the commit log message when the
	   command commits the final one in a chain of "fixup" commands, which
	   has been corrected.
	 * There are double frees and leaks around setup_revisions() API used
	   in "git stash show", which has been fixed, and setup_revisions()
	   API gained a wrapper to make it more ergonomic when using it with
	   strvec-manged argc/argv pairs.
	   (merge a04bc71725 jk/setup-revisions-freefix later to maint).
	 * Deal more gracefully with directory / file conflicts when the files
	   backend is used for ref storage, by failing only the ones that are
	   involved in the conflict while allowing others.
	 * "git last-modified" operating in non-recursive mode used to trigger
	   a BUG(), which has been corrected.
	 * The use of "git config get" command to learn how ANSI color
	   sequence is for a particular type, e.g., "git config get
	   --type=color --default=reset no.such.thing", isn't very ergonomic.
	   (merge e4dabf4fd6 ps/config-get-color-fixes later to maint).
	 * The "do you still use it?" message given by a command that is
	   deeply deprecated and allow us to suggest alternatives has been
	   updated.
	 * Clang-format update to let our control macros be formatted the way we
	   had them traditionally, e.g., "for_each_string_list_item()" without
	   space before the parentheses.
	 * A few places where a size_t value was cast to curl_off_t without
	   checking has been updated to use the existing helper function.
	 * "git reflog write" did not honor the configured user.name/email
	   which has been corrected.
	 * Handling of an empty subdirectory of .git/refs/ in the ref-files
	   backend has been corrected.
	 * Our CI script requires "sudo" that can be told to preserve
	   environment, but Ubuntu replaced with "sudo" with an implementation
	   that lacks the feature.  Work this around by reinstalling the
	   original version.
	 * The reftable backend learned to sanity check its on-disk data more
	   carefully.
	   (merge 466a3a1afd kn/reftable-consistency-checks later to maint).
	 * A lot of code clean-up of xdiff.
	   Split out of a larger topic.
	   (merge 8b9c5d2e3a en/xdiff-cleanup later to maint).
	 * "git format-patch --range-diff=... --notes=..." did not drive the
	   underlying range-diff with correct --notes parameter, ending up
	   comparing with different set of notes from its main patch output
	   you would get from "git format-patch --notes=..." for a singleton
	   patch.
	 * The code in "git add -p" and friends to iterate over hunks was
	   riddled with bugs, which has been corrected.
	 * A few more things that patch authors can do to help maintainer to
	   keep track of their topics better.
	   (merge 1a41698841 tb/doc-submitting-patches later to maint).
	 * An earlier addition to "git diff --no-index A B" to limit the
	   output with pathspec after the two directories misbehaved when
	   these directories were given with a trailing slash, which has been
	   corrected.
	 * The "--short" option of "git status" that meant output for humans
	   and "-z" option to show NUL delimited output format did not mix
	   well, and colored some but not all things.  The command has been
	   updated to color all elements consistently in such a case.
	 * Unicode width table update.
	 * GPG signing test set-up has been broken for a year, which has been
	   corrected.
	   (merge 516bf45749 jc/t1016-setup-fix later to maint).
	 * Recent OpenSSH creates the Unix domain socket to communicate with
	   ssh-agent under $HOME instead of /tmp, which causes our test to
	   fail doe to overly long pathname in our test environment, which has
	   been worked around by using "ssh-agent -T".
	 * strbuf_split*() to split a string into multiple strbufs is often a
	   wrong API to use.  A few uses of it have been removed by
	   simplifying the code.
	   (merge 2ab72a16d9 ob/gpg-interface-cleanup later to maint).
	 * "git shortlog" knows "--committer" and "--author" options, which
	   the command line completion (in contrib/) did not handle well,
	   which has been corrected.
	   (merge c568fa8e1c kf/log-shortlog-completion-fix later to maint).
	 * "git bisect" command did not react correctly to "git bisect help"
	   and "git bisect unknown", which has been corrected.
	   (merge 2bb3a012f3 rz/bisect-help-unknown later to maint).
	 * The 'q'(uit) command in "git add -p" has been improved to quit
	   without doing any meaningless work before leaving, and giving EOF
	   (typically control-D) to the prompt is made to behave the same way.
	 * The wildmatch code had a corner case bug that mistakenly makes
	   "foo**/bar" match with "foobar", which has been corrected.
	   (merge 1940a02dc1 jk/match-pathname-fix later to maint).
	 * Tests did not set up GNUPGHOME correctly, which is fixed but some
	   flaky tests are exposed in t1016, which needs to be addressed
	   before this topic can move forward.
	   (merge 6cd8369ef3 tz/test-prepare-gnupghome later to maint).
	 * The patterns used in the .gitignore files use backslash in the way
	   documented for fnmatch(3); document as such to reduce confusion.
	   (merge 8a6d158a1d jk/doc-backslash-in-exclude later to maint).
	 * The version of macos image used in GitHub CI has been updated to
	   macos-14, as the macos-13 that we have been using got deprecated.
	   Perforce binary used there has been changed to arm64 version to
	   match.
	   (merge 73b9cdb7c4 jc/ci-use-macos-14 later to maint).
	   (merge ffff0bb0da jc/ci-use-arm64-p4-on-macos later to maint).
	 * Other code cleanup, docfix, build fix, etc.
	   (merge 529a60a885 ua/t1517-short-help-tests later to maint).
	   (merge 22d421fed9 ac/deglobal-fmt-merge-log-config later to maint).
	   (merge a60203a015 dk/t7005-editor-updates later to maint).
	   (merge 16684b6fae ps/reftable-libgit2-cleanup later to maint).
	   (merge e5c27bd3d8 je/doc-add later to maint).
	   (merge 13296ac909 ps/object-store-midx-dedup-info later to maint).
	   (merge f9a6705d9a tc/t0450-harden later to maint).
	   (merge a66fc22bf9 rs/get-oid-with-flags-cleanup later to maint).
	   (merge 15b8abde07 js/mingw-includes-cleanup later to maint).
	   (merge 2cebca0582 tb/cat-file-objectmode-update later to maint).
	   (merge 8f487db07a kh/doc-patch-id-1 later to maint).

	   (merge 85333aa1af jk/test-delete-gpgsig-leakfix later to maint).
    2.51.2
	Bug Fixes
	 * Recently we attempted to improve "git diff -w --quiet" and friends
	   to handle cases where patch output would be suppressed, but it
	   introduced a bug that emits unnecessary output, which has been
	   corrected.
	 * The code to squelch output from "git diff -w --name-status"
	   etc. for paths that "git diff -w -p" would have stayed silent
	   leaked output from dry-run patch generation, which has been
	   corrected.
	 * Windows "real-time monitoring" interferes with the execution of
	   tests and affects negatively in both correctness and performance,
	   which has been disabled in Gitlab CI.
	 * An earlier addition to "git diff --no-index A B" to limit the
	   output with pathspec after the two directories misbehaved when
	   these directories were given with a trailing slash, which has been

	Also contains various documentation updates, code cleanups and minor fixups.

	   cf. <CABPp-BHFxxGrqKc0m==TjQNjDGdO=H5Rf6EFsf2nfE1=TuraOQ@mail.gmail.com>
	 * Fixes multiple crashes around midx write-out codepaths.
