Add a repository argument to allow callers of lookup_commit_reference
to be more specific about which repository to handle. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.

The code to try seeing if a fetch is necessary in a submodule
during a fetch with --recurse-submodules got confused when the path
to the submodule was changed in the range of commits in the
superproject, sometimes showing "(null)".  This has been corrected.

* sb/fix-fetching-moved-submodules:
  t5526: test recursive submodules when fetching moved submodules
  submodule: fix NULL correctness in renamed broken submodules

Build and test procedure for netrc credential helper (in contrib/)
has been updated.

* tz/cred-netrc-cleanup:
  git-credential-netrc: make "all" default target of Makefile
  git-credential-netrc: fix exit status when tests fail
  git-credential-netrc: use in-tree Git.pm for tests
  git-credential-netrc: minor whitespace cleanup in test script

test cleanup.

* jc/clean-after-sanity-tests:
  tests: clean after SANITY tests

Continuing with the idea to programmatically enumerate various
pieces of data required for command line completion, the codebase
has been taught to enumerate options prefixed with "--no-" to
negate them.

* nd/completion-negation:
  completion: collapse extra --no-.. options
  completion: suppress some -no- options
  parse-options: option to let --git-completion-helper show negative form

When user edits the patch in "git add -p" and the user's editor is
set to strip trailing whitespaces indiscriminately, an empty line
that is unchanged in the patch would become completely empty
(instead of a line with a sole SP on it).  The code introduced in
Git 2.17 timeframe failed to parse such a patch, but now it learned
to notice the situation and cope with it.

* pw/add-p-recount:
  add -p: fix counting empty context lines in edited patches

"git fetch-pack --all" used to unnecessarily fail upon seeing an
annotated tag that points at an object other than a commit.

* jk/fetch-all-peeled-fix:
  fetch-pack: test explicitly that --all can fetch tag references pointing to non-commits
  fetch-pack: don't try to fetch peel values with --all

"git send-pack --signed" (hence "git push --signed" over the http
transport) did not read user ident from the config mechanism to
determine whom to sign the push certificate as, which has been
corrected.

* ms/send-pack-honor-config:
  builtin/send-pack: populate the default configs

The recent addition of "partial clone" experimental feature kicked
in when it shouldn't, namely, when there is no partial-clone filter
defined even if extensions.partialclone is set.

* jh/partial-clone:
  list-objects: check if filter is NULL before using

Some flaky tests have been fixed.

* sg/gpg-tests-fix:
  tests: make forging GPG signed commits and tags more robust
  t7510-signed-commit: use 'test_must_fail'

Fix for 2.17-era regression around `core.safecrlf`.

* as/safecrlf-quiet-fix:
  config.c: fix regression for core.safecrlf false

Make refspec parsing codepath more robust.

* ab/refspec-init-fix:

Misc leak plugging.

* sb/plug-misc-leaks:
  sequencer.c: plug mem leak in git_sequencer_config
  sequencer.c: plug leaks in do_pick_commit
  submodule--helper: plug mem leak in print_default_remote
  refs/packed-backend.c: close fd of empty file

Instead of mucking with filesystem directly, use plumbing commands
update-ref etc. to manipulate the refs in the tests.

* cc/tests-without-assuming-ref-files-backend:
  t9104: kosherly remove remote refs

Code cleanup.

* sg/update-ref-stdin-cleanup:
  update-ref --stdin: use skip_prefix()

"git fetch --shallow-since=<cutoff>" that specifies the cut-off
point that is newer than the existing history used to end up
grabbing the entire history.  Such a request now errors out.

* nd/reject-empty-shallow-request:
  upload-pack: reject shallow requests that would return nothing

"git remote update" can take both a single remote nickname and a
nickname for remote groups, and the completion script (in contrib/)
has been taught about it.

* ls/complete-remote-update-names:
  completion: complete remote names too

Separate "rebase -p" codepath out of "rebase -i" implementation to
slim down the latter and make it easier to manage.

* ag/rebase-p:
  rebase: remove -p code from git-rebase--interactive.sh
  rebase: use the new git-rebase--preserve-merges.sh
  rebase: strip unused code in git-rebase--preserve-merges.sh
  rebase: introduce a dedicated backend for --preserve-merges

Continuing with the idea to programatically enumerate various
pieces of data required for command line completion, teach the
codebase to report the list of configuration variables
subcommands care about to help complete them.

* nd/complete-config-vars:
  completion: complete general config vars in two steps
  log-tree: allow to customize 'grafted' color
  completion: support case-insensitive config vars
  completion: keep other config var completion in camelCase
  completion: drop the hard coded list of config vars
  am: move advice.amWorkDir parsing back to advice.c
  advice: keep config name in camelCase in advice_config[]
  fsck: produce camelCase config key names
  help: add --config to list all available config
  fsck: factor out msg_id_info[] lazy initialization code
  grep: keep all colors in an array
  Add and use generic name->id mapping code for color slot parsing

The conversion to pass "the_repository" and then "a_repository"
throughout the object access API continues.

* sb/object-store-alloc:
  alloc: allow arbitrary repositories for alloc functions
  object: allow create_object to handle arbitrary repositories
  object: allow grow_object_hash to handle arbitrary repositories
  alloc: add repository argument to alloc_commit_index
  alloc: add repository argument to alloc_report

Modernize a less often used command.

* jk/show-index:
  show-index: update documentation for index v2
  make show-index a builtin

Clean up tests in t6xxx series about 'merge' command.

* en/merge-recursive-tests:
  t6036: prefer test_when_finished to manual cleanup in following test
  t6036, t6042: prefer test_cmp to sequences of test
  t6036, t6042: prefer test_path_is_file, test_path_is_missing
  t6036, t6042: use test_line_count instead of wc -l
  t6036, t6042: use test_create_repo to keep tests independent

"git diff" compares the index and the working tree.  For paths
added with intent-to-add bit, the command shows the full contents
of them as added, but the paths themselves were not marked as new
files.  They are now shown as new by default.

"git apply" learned the "--intent-to-add" option so that an
otherwise working-tree-only application of a patch will add new
paths to the index marked with the "intent-to-add" bit.

* nd/diff-apply-ita:
  apply: add --intent-to-add
  t2203: add a test about "diff HEAD" case
  diff: turn --ita-invisible-in-index on by default
  diff: ignore --ita-[in]visible-in-index when diffing worktree-to-tree

  commit: add short-circuit to paint_down_to_common()
  commit: use generation numbers for in_merge_bases()
  ref-filter: use generation number for --contains

  commit: use generations in paint_down_to_common()
  commit-graph: compute generation numbers
  commit: add generation number to struct commit
  ref-filter: fix outdated comment on in_commit_list

The in-core "commit" object had an all-purpose "void *util" field,
which was tricky to use especially in library-ish part of the
code.  All of the existing uses of the field has been migrated to a
more dedicated "commit-slab" mechanism and the field is eliminated.

* nd/commit-util-to-slab:
  commit.h: delete 'util' field in struct commit
  merge: use commit-slab in merge remote desc instead of commit->util
  log: use commit-slab in prepare_bases() instead of commit->util
  show-branch: note about its object flags usage

  blame: use commit-slab for blame suspects instead of commit->util
  commit-slab: support shared commit-slab
  commit-slab.h: code split

The bulk of "git submodule foreach" has been rewritten in C.
