To give ample warning for users wishing to override Git's the fall-back
for an unconfigured `init.defaultBranch` (in case we decide to change it
in a future Git version), let's introduce some advice that is shown upon
`git init` when that value is not set.
Note: two test cases in Git's test suite want to verify that the
`stderr` output of `git init` is empty. It is now necessary to suppress
the advice, we now do that via the `init.defaultBranch` setting. While
not strictly necessary, we also set this to `false` in
`test_create_repo()`.

We are about to introduce a message giving users running `git init` some
advice about `init.defaultBranch`. This will necessarily be done in
`repo_default_branch_name()`.
Not all code paths want to show that advice, though. In particular, the
`git clone` codepath _specifically_ asks for `init_db()` to be quiet,
via the `INIT_DB_QUIET` flag.
In preparation for showing users above-mentioned advice, let's change
the function signature of `get_default_branch_name()` to accept the
parameter `quiet`.

The 'dist' target uses a versioned temp directory, $(GIT_TARNAME), into
which it copies various files added to the distribution tarball. Should
it be necessary to remove this directory in the 'clean' target, since
the name depends on $(GIT_VERSION), the current HEAD must be positioned
on the same commit as when 'make dist' was issued. Otherwise, the target
will fail to remove that directory.
Create an '.dist-tmp-dir' directory and copy the various files into this
now un-versioned directory while creating the distribution tarball. Change
the 'clean' target to remove the '.dist-tmp-dir' directory, instead of the
version dependent $(GIT_TARNAME) directory.

To that end, we set a specific name for the initial branch. Ideally, we
would simply start out by calling `git branch -M initial-branch`, but
there is a bug in `git branch -M` that does not allow renaming branches
unless they already have commits. This will be fixed in the
`js/init-defaultbranch-advice` topic, and until that time, we use the
equivalent (but less intuitive) `git checkout -f --orphan`.

Long time ago when the _git_complete helper was introduced, _gitk was
replaced with __gitk_main, and a placeholder for backwards compatibility
pointing to __git_wrap_main_gitk was left in place.
When "__git_complete gitk __gitk_main" was called, that created the
__git_wrap__gitk_main helper, which is just basically "__git_func_wrap
__gitk_main" plus `complete` options.
Unfortunately the commit b0a4b2d257 (completion: add support for
backwards compatibility, 2012-05-19) missed a previous instance of a
call to _gitk in _git_gitk
So, basically we had __git_wrap__git_main -> __git_func_wrap __git_main ->
__git_complete_command gitk -> _git_gitk -> _gitk ->
__git_wrap__gitk_main -> __git_func_wrap __gitk_main -> __gitk_main.
There was never any need to call __git_func_wrap twice. Since _git_gitk
is always called inside the wrapper, it can call __gitk_main directly.
And then, in commit 441ecdab37 (completion: bash: remove old compat
wrappers, 2020-10-27) _gitk was removed, which triggers the following
error:
_git_gitk:9: command not found: _gitk
Let's call the correct function: __gitk_main.

Our custom packed_oid_list data structure is really just an oid_array in
disguise. Let's switch to using the generic structure, which shortens
and simplifies the code slightly.
There's one slightly awkward part: in the old code we copied a hash
straight from the mmap'd on-disk data into the final object_id. And now
we'll copy to a temporary oid, which we'll then pass to
oid_array_append(). But this is an operation we have to do all over the
commit-graph code already, since it mostly uses object_id structs
internally. I also measured "git commit-graph --append", which triggers
this code path, and it showed no difference.

When writing a commit graph, we collect a list of object ids in an
array, which we'll eventually copy into an array of "struct commit"
pointers. Before we do that, though, we count the number of distinct
commit entries. There's a subtle bug in this step, though.
We eliminate not only duplicate oids, but also in split mode, any oids
which are not commits or which are already in a graph file. However, the
loop starts at index 1, always counting index 0 as distinct. And indeed
it can't be a duplicate, since we check for those by comparing against
the previous entry, and there isn't one for index 0. But it could be a
commit that's already in a graph file, and we'd overcount the number of
commits by 1 in that case.
That turns out not to be a problem, though. The only things we do with
the count are:
- check if our count will overflow our data structures. But the limit
there is 2^31 commits, so while this is a useful check, the
off-by-one is not likely to matter.
- pre-allocate the array of commit pointers. But over-allocating by
one isn't a problem; we'll just waste a few extra bytes.
The bug would be easy enough to fix, but we can observe that neither of
those steps is necessary.
After building the actual commit array, we'll likewise check its count
for overflow. So the extra check of the distinct commit count here is
redundant.
And likewise we use ALLOC_GROW() when building the commit array, so
there's no need to preallocate it (it's possible that doing so is
slightly more efficient, but if we care we can just optimistically
allocate one slot for each oid; I didn't bother here).
So count_distinct_commits() isn't doing anything useful. Let's just get
rid of that step.
Note that a side effect of the function was that we sorted the list of
oids, which we do rely on in copy_oids_to_commits(), since it must also
skip the duplicates. So we'll move the qsort there. I didn't copy the
"TODO" about adding more progress meters. It's actually quite hard to
make a repository large enough for this qsort would take an appreciable
amount of time, so this doesn't seem like a useful note.

We provide oid_array_for_each_unique() for iterating over the
de-duplicated items in an array. But it's awkward to use for two
reasons:
1. It uses a callback, which means marshaling arguments into a struct
and passing it to the callback with a void parameter.
2. The callback doesn't know the numeric index of the oid we're
looking at. This is useful for things like progress meters.
Iterating with a for-loop is much more natural for some cases, but the
caller has to do the de-duping itself. However, we can provide a small
helper to make this easier (see the docstring in the header for an
example use).
The caller does have to remember to sort the array first. We could add
an assertion into the helper that array->sorted is set, but I didn't
want to complicate what is otherwise a pretty fast code path.
I also considered adding a full iterator type with init/next/end
functions (similar to what we have for hashmaps). But it ended up making
the callers much harder to read. This version keeps us close to a basic
for-loop.
Yet another option would be adding an option to sort the array and
compact out the duplicates. This would mean iterating over the array an
extra time, though that's probably not a big deal (we did just do an
O(n log n) sort). But we'd still have to write a for-loop to iterate, so
it doesn't really make anything easier for the caller.
No new test, since we'll convert the callback iterator (which is covered
by t0064, among other callers) to use the new code.

We define git_hash_algo and object_id in hash.h, but most of the utility
functions are declared in the main cache.h. Let's move them to hash.h
along with their struct definitions. This cleans up cache.h a bit, but
also avoids circular dependencies when other headers need to know about
these functions (e.g., if oid-array.h were to have an inline that used
oideq(), it couldn't include cache.h because it is itself included by
cache.h).
No including C files should be affected, because hash.h is always
included in cache.h already.
We do have to mention repository.h at the top of hash.h, though, since
we depend on the_repository in some of our inline functions.

Our tests for handling duplicates in oid-array provide only a single
duplicate for each number, so our sorted array looks like:
44 44 55 55 88 88 aa aa
A slightly more interesting test is to have multiple duplicates, which
makes sure that we not only skip the duplicate, but keep skipping until
we are out of the set of matching duplicates.
Unsurprisingly this works just fine, but it's worth beefing up this test
since we're about to change the duplicate-detection code.
Note that we do need to adjust the results on the lookup test, since it
is returning the index of the found item (and now we have more items
before our range, and the range itself is slightly larger, since we'll

Initially, we started converting this test script in anticipation for
renaming the default branch name to `main`. To that end, we partially
converted it to accommodate for that default branch name, marking the
now-failing test cases with a prereq that was designed to be fulfilled
once the rename was complete.
However, the effort to move to the branch name `main` needs quite a bit
longer, as it was decided that we need a deprecation phase first.
To avoid keeping t5526 in limbo for such a long time, we just made it
independent of the actual default branch name used by Git. Therefore,
that prereq is no longer necessary, and we can drop it.

To keep track of which object filters are allowed or not, 'git
upload-pack' stores the name of each filter in a string_list, and sets
it ->util pointer to be either 0 or 1, indicating whether it is banned
or allowed.
Later on, we attempt to clear that list, but we incorrectly ask for the
util pointers to be free()'d, too. This behavior (introduced back in
6dd3456a8c (upload-pack.c: allow banning certain object filter(s),
2020-08-03)) leads to an invalid free, and causes us to crash.
In order to trigger this, one needs to fetch from a server that (a) has
at least one object filter allowed, and (b) issue a fetch that contains
a subset of the allowed filters (i.e., we cannot ask for a banned
filter, since this causes us to die() before we hit the bogus
string_list_clear()).
In that case, whatever banned filters exist will cause a noop free()
(since those ->util pointers are set to 0), but the first allowed filter
we try to free will crash us.
We never noticed this in the tests because we didn't have an example of
setting 'uploadPackFilter' configuration variables and then following up
with a valid fetch. The first new 'git clone' prevents further
regression here. For good measure on top, add a test which checks the
same behavior at a tree depth greater than 0.

If 'git clone' couldn't execute 'transport_fetch_refs()' (e.g., because
of an error on the remote's side in 'git upload-pack'), then it will
silently ignore it.
Even though this has been the case at least since clone was ported to C
(way back in 8434c2f1af (Build in clone, 2008-04-27)), 'git fetch'
doesn't ignore these and reports any failures it sees.
That suggests that ignoring the return value in 'git clone' is simply an
oversight that should be corrected. That's exactly what this patch does.
(Noticing and fixing this is no coincidence, we'll want it in the next
patch in order to demonstrate a regression in 'git upload-pack' via a
'git clone'.)
There's no additional logging here, but that matches how 'git fetch'
handles the same case. An assumption there is that whichever part of
transport_fetch_refs() fails will complain loudly, so any additional
logging here is redundant.
