When generating the list of packs to store in a MIDX (when given the
`--write-midx` option), we include any cruft packs both during
--geometric and non-geometric repacks.
But the rules for when we do and don't have to check whether any of
those cruft packs were queued for deletion differ slightly between the
two cases.
But the two can be unified, provided there is a little bit of extra
detail added in the comment to clarify when it is safe to avoid checking
for any pending deletions (and why it is OK to do so even when not
required).

The `->util` field corresponding to each string_list_item is used to
track the existence of some pack at the beginning of a repack operation
was originally intended to be used as a bitfield.
This bitfield tracked:
- (1 << 0): whether or not the pack should be deleted
- (1 << 1): whether or not the pack is cruft
The previous commit removed the use of the second bit, but a future
patch (from a different series than this one) will introduce a new use
of it.
So we could stop treating the util pointer as a bitfield and instead
start treating it as if it were a boolean. But this would require some
backtracking when that later patch is applied.
Instead, let's avoid touching the ->util field directly, and instead
introduce convenience functions like:
- pack_mark_for_deletion()
- pack_is_marked_for_deletion()

When repacking with the `--write-midx` option, we invoke the function
`midx_included_packs()` in order to produce the list of packs we want to
include in the resulting MIDX.
This list is comprised of:
- existing .keep packs
- any pack(s) which were written earlier in the same process
- any unchanged packs when doing a `--geometric` repack
- any cruft packs
Prior to this patch, we stored pre-existing cruft and non-cruft packs
together (provided those packs are non-kept). This meant we needed an
additional bit to indicate which non-kept pack(s) were cruft versus
those that aren't.
But alternatively we can store cruft packs in a separate list, avoiding
the need for this extra bit, and simplifying the code below.

When there is:
- at least one pre-existing packfile (which is not marked as kept),
- repacking with the `-d` flag, and
- not doing a cruft repack
, then we pass a handful of additional options to the inner
`pack-objects` process, like `--unpack-unreachable`,
`--keep-unreachable`, and `--pack-loose-unreachable`, in addition to
marking any packs we just wrote for promisor remotes as kept in-core
(with `--keep-pack`, as opposed to the presence of a ".keep" file on
disk).
Because we store both cruft and non-cruft packs together in the same
`existing.non_kept_packs` list, it suffices to check its `nr` member to
see if it is zero or not.
But a following change will store cruft- and non-cruft packs separately,
meaning this check would break as a result. Prepare for this by
extracting this part of the check into a new helper function called
`has_existing_non_kept_packs()`.
This patch does not introduce any functional changes, but prepares us to
make a more isolated change in a subsequent patch.

To remove redundant packs at the end of a repacking operation, Git uses
its `remove_redundant_pack()` function in a loop over the set of
pre-existing, non-kept packs.
In a later commit, we will split this list into two, one for
pre-existing cruft pack(s), and another for non-cruft pack(s). Prepare
for this by factoring out the routine to loop over and delete redundant
packs into its own function.
Instead of calling `remove_redundant_pack()` directly, we now will call
`remove_redundant_existing_packs()`, which itself dispatches a call to
`remove_redundant_packs_1()`. Note that the geometric repacking code
will still call `remove_redundant_pack()` directly, but see the previous
commit for more details.
Having `remove_redundant_packs_1()` exist as a separate function may
seem like overkill in this patch. However, a later patch will call
`remove_redundant_packs_1()` once over two separate lists, so this
refactoring sets us up for that.

At the end of a repack (when given `-d`), Git attempts to remove any
packs which have been made "redundant" as a result of the repacking
operation. For example, an all-into-one (`-A` or `-a`) repack makes
every pre-existing pack which is not marked as kept redundant. Geometric
repacks (with `--geometric=<n>`) make any packs which were rolled up
redundant, and so on.
But before deleting the set of packs we think are redundant, we first
check to see whether or not we just wrote a pack which is identical to
any one of the packs we were going to delete. When this is the case, Git
must avoid deleting that pack, since it matches a pack we just wrote
(so deleting it may cause the repository to become corrupt).
Right now we only process the list of non-kept packs in a single pass.
But a future change will split the existing non-kept packs further into
two lists: one for cruft packs, and another for non-cruft packs.
Factor out this routine to prepare for calling it twice on two separate
lists in a future patch.

The repack machinery needs to keep track of which packfiles were present
in the repository at the beginning of a repack, segmented by whether or
not each pack is marked as kept.
The names of these packs are stored in two `string_list`s, corresponding
to kept- and non-kept packs, respectively. As a consequence, many
functions within the repack code need to take both `string_list`s as
arguments, leading to code like this:
ret = write_cruft_pack(&cruft_po_args, packtmp, pack_prefix,
cruft_expiration, &names,
&existing_nonkept_packs, /* <- */
&existing_kept_packs); /* <- */
Wrap up this pair of `string_list`s into a single structure that stores
both. This saves us from having to pass both string lists separately,
and prepares for adding additional fields to this structure.

The completion code can be told to use a particular completion for
aliases that shell out by using ': git <cmd> ;' as the first command of
the alias. This only works if <cmd> and the semicolon are separated by a
space, since if the space is missing __git_aliased_command returns (for
example) 'checkout;' instead of just 'checkout', and then
__git_complete_command fails to find a completion for 'checkout;'.
The examples have that space but it's not clear if it's just for
style or if it's mandatory. Explicitly mention it.

Make the implementation more robust by:

- using a stricter pattern for --get-regexp to avoid false hits

This test was introduced by commit 0c164ae7a ("rebase -i: add another
reword test", 2021-08-20). I didn't quite get what it was meant to do,
so here's an explanation from Phillip:
The purpose of the test is to ensure that
(i) There are no uncommitted changes when the editor runs. i.e., we
commit without running the editor and then reword by amending
that commit. This ensures that we have the same user experience
whether or not the commit was fast-forwarded [1].
(ii) That the todo list is re-read after the commit has been reworded.
This is to allow the user to update the todo list while the rebase
is paused for editing the commit message.

`git diff-index` may return incorrect deleted entries when fsmonitor
is used in a repository with git submodules. This can be observed on
Mac machines, but it can affect all other supported platforms too.
If fsmonitor is used, `stat *st` is not initialized if cache_entry has
CE_FSMONITOR_VALID set. But, there are three call sites that rely on stat
afterwards, which can result in incorrect results.
This change partially reverts commit 4f3d6d02 (fsmonitor: skip lstat

When running in the Windows Subsystem for Linux (WSL), it is usually
necessary to use the Git Credential Manager for authentication when
performing the background fetches.
This requires interoperability between the Windows Subsystem for Linux
and the Windows host to work, which uses so-called vsocks, i.e. sockets
intended for communcations between virtual machines and the host they
are running on.
However, when Git is configured to run background maintenance via
`systemd`, the address families available to those maintenance processes
are restricted, and did not include `AF_VSOCK`. This leads to problems
e.g. when a background fetch tries to access github.com:
systemd[437]: Starting Optimize Git repositories data...
git[747387]: WSL (747387) ERROR: UtilBindVsockAnyPort:285: socket failed 97
git[747381]: fatal: could not read Username for 'https://github.com': No such device or address

systemd[437]: git-maintenance@hourly.service: Failed with result 'exit-code'.
systemd[437]: Failed to start Optimize Git repositories data.
Address this (pun intended) by adding the `AF_VSOCK` address family to
the allow list.

When `git switch --track ` is to be completed, only remote refs are
eligible because that is what the `--track` option targets.
And when the short-hand `-t` is used instead, the same _should_ happen.
Let's make it so.
Note that the bug exists both in the completions of `switch` and
`completion`, even if it manifests in slightly different ways: While
the completion of `git switch -t ` will not even look at remote refs,
the completion of `git checkout -t ` will look at both remote _and_
local refs. Both should look only at remote refs.

The `--trailer` option takes a "<token>=<value>" argument, for example
--trailer "Acked-by=Bob"
And in this exampple it is understood that "Acked-by" is the <token>.
However, the user can use a shorter "ack" string by defining
configuration like
git config trailer.ack.key "Acked-by"
However, in the docs we define the above configuration as
trailer.<token>.key
so the <token> can mean either the longer "Acked-by" or the shorter
"ack".
Separate the two meanings of <token> into <key> and <keyAlias>, and

The phrase "join whitespace-continued values" requires some additional
context. For example, "whitespace" means newlines (not just space
characters), and "join" means to join only the multiple lines together
for a single trailer (and not that we are joining multiple trailers
together). That is, "join" means to convert
token: This is a very long value, with spaces and
newlines in it.
to
token: This is a very long value, with spaces and newlines in it.
and does not mean to convert
token: value1
token: value2
to

By using "test_config" instead of "git config", we avoid leaking
configuration state across test cases. This in turn helps to make the
tests more self-contained, by explicitly capturing the configuration
setup. It then makes it easier to add tests anywhere in this 1500+ line
file, without worrying about what implicit state was set in some prior
test case defined earlier up in the script.
This commit was created mechanically as follows: we changed the first
occurrence of a particular "git config trailer.*" option, then ran the
tests repeatedly to see which ones broke, adding in the extra
"test_config" equivalents to make them pass again. In addition, in some
test cases we removed "git config --unset ..." lines because they were
no longer necessary (as the --unset was being used to clean up leaked
configuration state from earlier test cases).
The process described above was done repeatedly until there were no more
unbridled "git config" invocations. Some "git config" invocations still
do exist in the script, but they were already cleaned up properly with
test_when_finished "git config --remove-section ..."
so they were left alone.
Note that these cleanups result in generally longer test case setups
because the previously hidden state is now being exposed. Although we
could then clean up the test cases' "expected" values to be less
verbose (the verbosity arising from the use of implicit state), we
choose not to do so here, to make sure that this cleanup does not change
any meanings behind the test cases.
