There's not currently any way to free the resources associated with a
decoration struct. As a result, we have several memory leaks which
cannot easily be plugged.
Let's add a "clear" function and make use of it in the example code of
t9004. This removes the only leak from that script, so we can mark it as
passing the leak sanitizer.
Curiously this leak is found only when running SANITIZE=leak with clang,
but not with gcc. But it is a bog-standard leak: we allocate some
memory in a local variable struct, and then exit main() without
releasing it. I'm not sure why gcc doesn't find it. After this
patch, both compilers report it as leak-free.
Note that the clear function takes a callback to free the individual
entries. That's not needed for our example (which is just decorating
with ints), but will be for real callers.

When doing a `--geometric` repack, we make sure that the preferred pack
(if writing a MIDX) is the largest pack that we *didn't* repack. That
has the effect of keeping the preferred pack in sync with the pack
containing a majority of the repository's reachable objects.
But if the repository happens to double in size, we'll repack
everything. Here we don't specify any `--preferred-pack`, and instead
let the MIDX code choose.
In the past, that worked fine, since there would only be one pack to
choose from: the one we just wrote. But it's no longer necessarily the
case that there is one pack to choose from. It's possible that the
repository also has a cruft pack, too.
If the cruft pack happens to come earlier in lexical order (and has an
earlier mtime than any non-cruft pack), we'll pick that pack as
preferred. This makes it impossible to reuse chunks of the reachable
pack verbatim from pack-objects, so is sub-optimal.
Luckily, this is a somewhat rare circumstance to be in, since we would
have to repack the entire repository during a `--geometric` repack, and
the cruft pack would have to sort ahead of the pack we just created.

Cruft packs are an alternative mechanism for storing a collection of
unreachable objects whose mtimes are recent enough to avoid being
pruned out of the repository.
When cruft packs were first introduced back in b757353676
(builtin/pack-objects.c: --cruft without expiration, 2022-05-20) and
a7d493833f (builtin/pack-objects.c: --cruft with expiration,
2022-05-20), the recommended workflow consisted of:
- Repacking periodically, either by packing anything loose in the
repository (via `git repack -d`) or producing a geometric sequence
of packs (via `git repack --geometric=<d> -d`).
- Every so often, splitting the repository into two packs, one cruft
to store the unreachable objects, and another non-cruft pack to
store the reachable objects.
Repositories may (out of band with the above) choose periodically to
prune out some unreachable objects which have aged out of the grace
period by generating a pack with `--cruft-expiration=<approxidate>`.
This allowed repositories to maintain relatively few packs on average,
and quarantine unreachable objects together in a cruft pack, avoiding
the pitfalls of holding unreachable objects as loose while they age out
(for more, see some of the details in 3d89a8c118
(Documentation/technical: add cruft-packs.txt, 2022-05-20)).
This all works, but can be costly from an I/O-perspective when
frequently repacking a repository that has many unreachable objects.
This problem is exacerbated when those unreachable objects are rarely
(if every) pruned.
Since there is at most one cruft pack in the above scheme, each time we
update the cruft pack it must be rewritten from scratch. Because much of
the pack is reused, this is a relatively inexpensive operation from a
CPU-perspective, but is very costly in terms of I/O since we end up
rewriting basically the same pack (plus any new unreachable objects that
have entered the repository since the last time a cruft pack was
generated).
At the time, we decided against implementing more robust support for
multiple cruft packs. This patch implements that support which we were
lacking.
Introduce a new option `--max-cruft-size` which allows repositories to
accumulate cruft packs up to a given size, after which point a new
generation of cruft packs can accumulate until it reaches the maximum
size, and so on. To generate a new cruft pack, the process works like
so:
- Sort a list of any existing cruft packs in ascending order of pack
size.
- Starting from the beginning of the list, group cruft packs together
while the accumulated size is smaller than the maximum specified
pack size.
- Combine the objects in these cruft packs together into a new cruft
pack, along with any other unreachable objects which have since
entered the repository.
Once a cruft pack grows beyond the size specified via `--max-cruft-size`
the pack is effectively frozen. This limits the I/O churn up to a
quadratic function of the value specified by the `--max-cruft-size`
option, instead of behaving quadratically in the number of total
unreachable objects.
When pruning unreachable objects, we bypass the new code paths which
combine small cruft packs together, and instead start from scratch,
passing in the appropriate `--max-pack-size` down to `pack-objects`,
putting it in charge of keeping the resulting set of cruft packs sized
correctly.
This may seem like further I/O churn, but in practice it isn't so bad.
We could prune old cruft packs for whom all or most objects are removed,
and then generate a new cruft pack with just the remaining set of
objects. But this additional complexity buys us relatively little,
because most objects end up being pruned anyway, so the I/O churn is
well contained.

The repack builtin takes a `--max-pack-size` command-line argument which
it uses to feed into any of the pack-objects children that it may spawn
when generating a new pack.
This option is parsed with OPT_STRING, meaning that we'll accept
anything as input, punting on more fine-grained validation until we get
down into pack-objects.
This is fine, but it's wasteful to spend an entire sub-process just to
figure out that one of its option is bogus. Instead, parse the value of
`--max-pack-size` with OPT_MAGNITUDE in 'git repack', and then pass the
known-good result down to pack-objects.

When running "commit-graph verify", we call free_commit_graph(). That's
sufficient for the case of a single graph file, but if we loaded a chain
of split graph files, they form a linked list via the base_graph
pointers. We need to free all of them, or we leak all but the first
struct.
We can make this work by teaching free_commit_graph() to walk the
base_graph pointers and free each element. This in turn lets us simplify
close_commit_graph(), which does the same thing by recursion (we cannot
just use close_commit_graph() in "commit-graph verify", as the function
takes a pointer to an object store, and the verify command creates a
single one-off graph struct).
While indenting the code in free_commit_graph() for the loop, I noticed
that setting g->data to NULL is rather pointless, as we free the struct
a few lines later. So I cleaned that up while we're here.

The obvious solution is to free it, but we need to look at the contents

free it in both code paths. But since the commit that the list points to
is longer-lived than the list itself, we can just dereference it
immediately, free the list, and then continue with the existing logic.

A previous commit has implemented `git repack --filter=<filter-spec>` to
allow users to filter out some objects from the main pack and move them
into a new different pack.
It would be nice if this new different pack could be created in a
different directory than the regular pack. This would make it possible
to move large blobs into a pack on a different kind of storage, for
example cheaper storage.
Even in a different directory, this pack can be accessible if, for
example, the Git alternates mechanism is used to point to it. In fact
not using the Git alternates mechanism can corrupt a repo as the
generated pack containing the filtered objects might not be accessible
from the repo any more. So setting up the Git alternates mechanism
should be done before using this feature if the user wants the repo to
be fully usable while this feature is used.
In some cases, like when a repo has just been cloned or when there is no
other activity in the repo, it's Ok to setup the Git alternates
mechanism afterwards though. It's also Ok to just inspect the generated
packfile containing the filtered objects and then just move it into the
'.git/objects/pack/' directory manually. That's why it's not necessary
for this command to check that the Git alternates mechanism has been
already setup.

options work well with `--max-pack-size`.

This new option puts the objects specified by `<filter-spec>` into a
separate packfile.
This could be useful if, for example, some blobs take up a lot of
precious space on fast storage while they are rarely accessed. It could
make sense to move them into a separate cheaper, though slower, storage.
It's possible to find which new packfile contains the filtered out
objects using one of the following:
- `git verify-pack -v ...`,
- `test-tool find-pack ...`, which a previous commit added,
- `--filter-to=<dir>`, which a following commit will add to specify
where the pack containing the filtered out objects will be.
This feature is implemented by running `git pack-objects` twice in a
row. The first command is run with `--filter=<filter-spec>`, using the
specified filter. It packs objects while omitting the objects specified
by the filter. Then another `git pack-objects` command is launched using
`--stdin-packs`. We pass it all the previously existing packs into its
stdin, so that it will pack all the objects in the previously existing
packs. But we also pass into its stdin, the pack created by the previous
`git pack-objects --filter=<filter-spec>` command as well as the kept
packs, all prefixed with '^', so that the objects in these packs will be
omitted from the resulting pack. The result is that only the objects
filtered out by the first `git pack-objects` command are in the pack
resulting from the second `git pack-objects` command.
As the interactions with kept packs are a bit tricky, a few related
tests are added.
