Now that multi-pack reuse is supported, enable it via the
feature.experimental configuration in addition to the classic
`pack.allowPackReuse`.
This will allow more users to experiment with the new behavior who might
not otherwise be aware of the existing `pack.allowPackReuse`
configuration option.
The enum with values NO_PACK_REUSE, SINGLE_PACK_REUSE, and
MULTI_PACK_REUSE is defined statically in builtin/pack-objects.c's
compilation unit. We could hoist that enum into a scope visible from the
repository_settings struct, and then use that enum value in
pack-objects. Instead, define a single int that indicates what
pack-objects's default value should be to avoid additional unnecessary
code movement.
Though `feature.experimental` implies `pack.allowPackReuse=multi`, this
can still be overridden by explicitly setting the latter configuration
to either "single" or "false". Tests covering all of these cases are
showin t5332.

In 70c70de616 (refs: complete list of special refs, 2023-12-14) we have
inrtoduced a new `is_special_ref()` function that classifies some refs
as being special. The rule is that special refs are exclusively read and
written via the filesystem directly, whereas normal refs exclucsively go
via the refs API.
The intent of that commit was to record the status quo so that we know
to route reads of such special refs consistently. Eventually, the list
should be reduced to its bare minimum of refs which really are special,
namely FETCH_HEAD and MERGE_HEAD.
Follow up on this promise and convert the AUTO_MERGE ref to become a
normal pseudo-ref by using the refs API to both read and write it
instead of accessing the filesystem directly.

When creating a worktree we create the worktree's ref database manually
by first writing a "HEAD" file so that the directory is recognized as a
Git repository by other commands, and then running git-update-ref(1) or
git-symbolic-ref(1) to write the actual value. But while this is fine
for the files backend, this logic simply assumes too much about how the
ref backend works and will leave behind an invalid ref database once any
other ref backend lands.
Refactor the code to instead use `refs_init_db()` to initialize the ref
database so that git-worktree(1) itself does not need to know about how
to initialize it. This will allow future ref backends to customize how
the per-worktree ref database is set up. Furthermore, as we now already
have a worktree ref store around, we can also avoid spawning external
commands to write the HEAD reference and instead use the refs API to do
so.
Note that we do not have an equivalent to passing the `--quiet` flag to
git-symbolic-ref(1) as we did before. This flag does not have an effect
anyway though, as git-symbolic-ref(1) only honors it when reading a
symref, but never when writing one.

SUMMARY: LeakSanitizer: 32 byte(s) leaked in 1 allocation(s).
Aborted
What happens is this:
0. We construct a bogus pack with a duplicate object in it and trigger
index-pack.
1. We spawn a bunch of worker threads to resolve deltas (on my system
it is 16 threads).
2. One of the threads sees the duplicate object and bails by calling
exit(), taking down all of the threads. This is expected and is the
point of the test.
3. At the time exit() is called, we may still be spawning threads from
the main process via pthread_create(). LSan hooks thread creation
to update its book-keeping; it has to know where each thread's
stack is (so it can find entry points for reachable memory). So it
calls pthread_getattr_np() to get information about the new thread.
That may allocate memory that must be freed with a matching call to
pthread_attr_destroy(). Probably LSan does that immediately, but
if you're unlucky enough, the exit() will happen while it's between
those two calls, and the allocated pthread_attr_t appears as a
leak.
This isn't a real leak. It's not even in our code, but rather in the
LSan instrumentation code. So we could just ignore it. But the false
positive can cause people to waste time tracking it down.
It's possibly something that LSan could protect against (e.g., cover the
getattr/destroy pair with a mutex, and then in the final post-exit()
check for leaks try to take the same mutex). But I don't know enough
about LSan to say if that's a reasonable approach or not (or if my
analysis is even completely correct).
In the meantime, it's pretty easy to avoid the race by making creation
of the worker threads "atomic". That is, we'll spawn all of them before
letting any of them start to work. That's easy to do because we already
have a work_lock() mutex for handing out that work. If the main process
takes it, then all of the threads will immediately block until we've
finished spawning and released it.
This shouldn't make any practical difference for non-LSan runs. The
thread spawning is quick, and could happen before any worker thread gets
scheduled anyway.
Probably other spots that use threads are subject to the same issues.
But since we have to manually insert locking (and since this really is
kind of a hack), let's not bother with them unless somebody experiences
a similar racy false-positive in practice.

Introduce a new "extensions.refStorage" extension that allows us to
specify the ref storage format used by a repository. For now, the only
supported format is the "files" format, but this list will likely soon
be extended to also support the upcoming "reftable" format.
There have been discussions on the Git mailing list in the past around
how exactly this extension should look like. One alternative [1] that
was discussed was whether it would make sense to model the extension in
such a way that backends are arbitrarily stackable. This would allow for
a combined value of e.g. "loose,packed-refs" or "loose,reftable", which
indicates that new refs would be written via "loose" files backend and
compressed into "packed-refs" or "reftable" backends, respectively.
It is arguable though whether this flexibility and the complexity that
it brings with it is really required for now. It is not foreseeable that
there will be a proliferation of backends in the near-term future, and
the current set of existing formats and formats which are on the horizon
can easily be configured with the much simpler proposal where we have a
single value, only.
Furthermore, if we ever see that we indeed want to gain the ability to
arbitrarily stack the ref formats, then we can adapt the current
extension rather easily. Given that Git clients will refuse any unknown
value for the "extensions.refStorage" extension they would also know to
ignore a stacked "loose,packed-refs" in the future.
So let's stick with the easy proposal for the time being and wire up the
extension.

In order to discern which ref storage format a repository is supposed to
use we need to start setting up and/or discovering the format. This
needs to happen in two separate code paths.
- The first path is when we create a repository via `init_db()`. When
we are re-initializing a preexisting repository we need to retain
the previously used ref storage format -- if the user asked for a
different format then this indicates an error and we error out.
Otherwise we either initialize the repository with the format asked
for by the user or the default format, which currently is the
"files" backend.
- The second path is when discovering repositories, where we need to
read the config of that repository. There is not yet any way to
configure something other than the "files" backend, so we can just
blindly set the ref storage format to this backend.
Wire up this logic so that we have the ref storage format always readily
available when needed. As there is only a single backend and because it
is not configurable we cannot yet verify that this tracking works as
expected via tests, but tests will be added in subsequent commits. To
countermand this ommission now though, raise a BUG() in case the ref
storage format is not set up properly in `ref_store_init()`.

93851746 (parse-options: decouple "--end-of-options" and "--",
2023-12-06) updated the world order to make callers of parse-options
that set PARSE_OPT_KEEP_UNKNOWN_OPT responsible for deciding what to
do with "--end-of-options" they may see after parse_options() returns.
This made a previous bug in sparse-checkout more visible; namely,
that
git sparse-checkout [add|set] --[no-]cone --end-of-options ...
would simply treat "--end-of-options" as one of the paths to include in
the sparse-checkout. But this was already problematic before; namely,
git sparse-checkout [add|set| --[no-]cone --sikp-checks ...
would not give an error on the mis-typed "--skip-checks" but instead
simply treat "--sikp-checks" as a path or pattern to include in the
sparse-checkout, which is highly unfriendly.
This behavior began when the command was converted to parse-options in
7bffca95ea (sparse-checkout: add '--stdin' option to set subcommand,
2019-11-21). Back then it was just called KEEP_UNKNOWN. Later it was
renamed to KEEP_UNKNOWN_OPT in 99d86d60e5 (parse-options:
PARSE_OPT_KEEP_UNKNOWN only applies to --options, 2022-08-19) to clarify
that it was only about dashed options; we always keep non-option
arguments. Looking at that original patch, both Peff and I think that
the author was simply confused about the mis-named option, and really
just wanted to keep the non-option arguments. We never should have used
the flag all along (and the other cases were cargo-culted within the
file).
Remove the erroneous PARSE_OPT_KEEP_UNKNOWN_OPT flag now to fix this
bug. Note that this does mean that anyone who might have been using
git sparse-checkout [add|set] [--[no-]cone] --foo --bar
to request paths or patterns '--foo' and '--bar' will now have to use
git sparse-checkout [add|set] [--[no-]cone] -- --foo --bar
That makes sparse-checkout more consistent with other git commands,
provides users much friendlier error messages and behavior, and is
consistent with the all-caps warning in git-sparse-checkout.txt that
this command "is experimental...its behavior...will likely change". :-)
