When a supposedly no-op "git repack" runs across a second boundary,
because the command always touches the MIDX file and updates its
timestamp, "ls -l $GIT_DIR/objects/pack/" before and after the
operation can change, which causes such a test to fail. Only
compare the *.pack files in the directory before and after the
operation to work around this flakyness.
Arguably, git-repack(1) should learn to not rewrite the MIDX in case
we know it is already up-to-date. But this is not a new problem
introduced via the new geometric maintenance task, so for now it
should be good enough to paper over the issue.

In match_pathname(), which we use for matching .gitignore and
.gitattribute patterns, we are comparing paths with fnmatch patterns
(actually our extended wildmatch, which will be important). There's an
extra optimization there: we pre-compute the number of non-wildcard
characters at the beginning of the pattern and do an fspathncmp() on
that prefix.
That lets us avoid fnmatch entirely on patterns without wildcards, and
shrinks the amount of work we hand off to fnmatch. For a pattern like
"foo*.txt" and a path "foobar.txt", we'd cut away the matching "foo"
prefix and just pass "*.txt" and "bar.txt" to fnmatch().
But this misses a subtle corner case. In fnmatch(), we'll think
"bar.txt" is the start of the path, but it's not. This doesn't matter
for the pattern above, but consider the wildmatch pattern "foo**/bar"
and the path "foobar". These two should not match, because there is no
file named "bar", and the "**" applies only to the containing directory
name. But after removing the "foo" prefix, fnmatch will get "**/bar" and
"bar", which it does consider a match, because "**/" can match zero
directories.
We can solve this by giving fnmatch a bit more context. As long as it
has one byte of the matched prefix, then it will know that "bar" is not
the start of the path. In this example it would get "o**/bar" and
"obar", and realize that they cannot match.

As an optimization, we use fspathncmp() to match a prefix of the pattern
that does not contain any wildcards, and then pass the remainder to
fnmatch(). If it has matched the whole thing, we can return early.
Let's shift this early-return check to before we tweak the pattern and
name strings. That will gives us more flexibility with that tweaking.
It might also save a few instructions, but I couldn't measure any
improvement in doing so (and I wouldn't be surprised if an optimizing
compiler could figure that out itself).

Option q implies d, i.e., it marks any undecided hunks towards the
bottom of the hunk array as skipped. This is unnecessary; later code
treats undecided and skipped hunks the same: The only functions that
use UNDECIDED_HUNK and SKIP_HUNK are patch_update_file() itself (but
not after its big for loop) and its helpers get_first_undecided() and
display_hunks().
Streamline the handling of option q by quitting immediately.

We have two different repacking strategies in Git:
- The "gc" strategy uses git-gc(1).
- The "incremental" strategy uses multi-pack indices and `git
multi-pack-index repack` to merge together smaller packfiles as
determined by a specific batch size.
The former strategy is our old and trusted default, whereas the latter
has historically been used for our scheduled maintenance. But both
strategies have their shortcomings:
- The "gc" strategy performs regular all-into-one repacks. Furthermore
it is rather inflexible, as it is not easily possible for a user to
enable or disable specific subtasks.
- The "incremental" strategy is not a full replacement for the "gc"
strategy as it doesn't know to prune stale data.
So today, we don't have a strategy that is well-suited for large repos
while being a full replacement for the "gc" strategy.
Introduce a new "geometric" strategy that aims to fill this gap. This
strategy invokes all the usual cleanup tasks that git-gc(1) does like
pruning reflogs and rerere caches as well as stale worktrees. But where
it differs from both the "gc" and "incremental" strategy is that it uses
our geometric repacking infrastructure exposed by git-repack(1) to
repack packfiles. The advantage of geometric repacking is that we only
need to perform an all-into-one repack when the object count in a repo
has grown significantly.
One downside of this strategy is that pruning of unreferenced objects is
not going to happen regularly anymore. Every geometric repack knows to
soak up all loose objects regardless of their reachability, and merging
two or more packs doesn't consider reachability, either. Consequently,
the number of unreachable objects will grow over time.
This is remedied by doing an all-into-one repack instead of a geometric
repack whenever we determine that the geometric repack would end up
merging all packfiles anyway. This all-into-one repack then performs our
usual reachability checks and writes unreachable objects into a cruft
pack. As cruft packs won't ever be merged during geometric repacks we
can thus phase out these objects over time.
Of course, this still means that we retain unreachable objects for far
longer than with the "gc" strategy. But the maintenance strategy is
intended especially for large repositories, where the basic assumption
is that the set of unreachable objects will be significantly dwarfed by
the number of reachable objects.
If this assumption is ever proven to be too disadvantageous we could for
example introduce a time-based strategy: if the largest packfile has not
been touched for longer than $T, we perform an all-into-one repack. But
for now, such a mechanism is deferred into the future as it is not clear
yet whether it is needed in the first place.

While the user can pick the "incremental" maintenance strategy, it is
not possible to explicitly use the "gc" strategy. This has two
downsides:
- It is impossible to use the default "gc" strategy for a specific
repository when the strategy was globally set to a different strategy.
- It is not possible to use git-gc(1) for scheduled maintenance.
Address these issues by making making the "gc" strategy configurable.
Furthermore, extend the strategy so that git-gc(1) runs for both manual
and scheduled maintenance.
