When starting a reftable transaction we lock all stacks we are about to
modify. While it may happen that the stack is out-of-date at this point
in time we don't really care: transactional updates encode the expected
state of a certain reference, so all that we really want to verify is
that the _current_ value matches that expected state.
Pass `REFTABLE_STACK_NEW_ADDITION_RELOAD` when locking the stack such
that an out-of-date stack will be reloaded after having been locked.
This change is safe because all verifications of the expected state
happen after this step anyway.
Add a testcase that verifies that many writers are now able to write to
the stack concurrently without failures and with a deterministic end
result.

In `reftable_stack_new_addition()` we first lock the stack and then
check whether it is still up-to-date. If it is not we return an error to
the caller indicating that the stack is outdated.
This is overly restrictive in our ref transaction interface though: we
lock the stack right before we start to verify the transaction, so we do
not really care whether it is outdated or not. What we really want is
that the stack is up-to-date after it has been locked so that we can
verify queued updates against its current state while we know that it is
locked for concurrent modification.
Introduce a new flag `REFTABLE_STACK_NEW_ADDITION_RELOAD` that alters
the behaviour of `reftable_stack_init_addition()` in this case: when we
notice that it is out-of-date we reload it instead of returning an error
to the caller.
This logic will be wired up in the reftable backend in the next commit.

When multiple concurrent processes try to update references in a
repository they may try to lock the same lockfiles. This can happen even
when the updates are non-conflicting and can both be applied, so it
doesn't always make sense to abort the transaction immediately. Both the
"loose" and "packed" backends thus have a grace period that they wait
for the lock to be released that can be controlled via the config values
"core.filesRefLockTimeout" and "core.packedRefsTimeout", respectively.
The reftable backend doesn't have such a setting yet and instead fails
immediately when it sees such a lock. But the exact same concepts apply
here as they do apply to the other backends.
Introduce a new "reftable.lockTimeout" config that controls how long we
may wait for a "tables.list" lock to be released. The default value of
this config is 100ms, which is the same default as we have it for the
"loose" backend.
Note that even though we also lock individual tables, this config really
only applies to the "tables.list" file. This is because individual
tables are only ever locked when we already hold the "tables.list" lock
during compaction. When we observe such a lock we in fact do not want to
compact the table at all because it is already in the process of being
compacted by a concurrent process. So applying the same timeout here
would not make any sense and only delay progress.

When f4dbdfc4d5 (commit-graph: clean up leaked memory during write,

e103f7276f (commit-graph: return with errors during write, 2019-06-12)
made it unnecessary, as it was then followed by a free() call for the
allocated string.
The code moved to write_commit_graph_file() in the meantime and the
string pointer is now part of a struct, but the function's only caller
still cleans up the allocation. Drop the superfluous UNLEAK.

git archive checks whether pathspec arguments match anything to avoid
surprises due to typos and later loads the index to get attributes.
This order was OK when these features were introduced by ba053ea96c
(archive: do not read .gitattributes in working directory, 2009-04-18)
and d5f53d6d6f (archive: complain about path specs that don't match
anything, 2009-12-12).
But when attribute matching was added to pathspec in b0db704652
(pathspec: allow querying for attributes, 2017-03-13), the pathspec
checker in git archive did not support it fully, because it lacks the
attributes from the index.
Load the index earlier, before the pathspec check, to support attr
pathspecs.

The diff machinery has two ways to detect changes to set the exit code:
Just comparing hashes and comparing blob contents. The latter is needed
if certain changes have to be ignored, e.g. with --ignore-space-change
or --ignore-matching-lines. It's enabled by the diff_options flag
diff_from_contents.
The code for handling binary files added by 1aaf69e669 (diff: shortcut
for diff'ing two binary SHA-1 objects, 2014-08-16) always uses a quick
hash-only comparison, even if the slow way is taken. We need it to
report a hash difference as a change for the purpose of setting the
exit code, though, but it never did. Fix that.
d7b97b7185 (diff: let external diffs report that changes are
uninteresting, 2024-06-09) set diff_from_contents if external diff
programs are allowed. This is the default e.g. for git diff, and so
that change exposed the inconsistency much more widely.

It has been reported than running
git submodule status --recurse | grep -q ^+
results in an unexpected error message
fatal: failed to recurse into submodule $submodule
When "git submodule--helper" recurses into a submodule it creates a
child process. If that process fails then the error message above is
displayed by the parent. In the case above the child is killed by
SIGPIPE as "grep -q" exits as soon as it sees the first match. Fix this
by propagating SIGPIPE so that it is visible to the process running
git. We could propagate other signals but I'm not sure there is much
value in doing that. In the common case of the user pressing Ctrl-C or
Ctrl-\ then SIGINT or SIGQUIT will be sent to the foreground process
group and so the parent process will receive the same signal as the
child.
