96e832a5fd (sequencer (rebase -i): refactor setting the reflog
message, 2017-01-02), it gained another user in
9055e401dd (sequencer: introduce new commands to reset the revision,

9cf6d3357a (Add git-index-pack utility, 2005-10-12) and
466dbc42f5 (receive-pack: Send internal errors over side-band #2,
2010-02-10) we added these static functions and forward-declared their
__attribute__((printf)).
I think this may have been to work around some compiler limitation at
the time, but in any case we have a lot of code that uses the briefer
way of declaring these that I'm using here, so if we had any such
issues with compilers we'd have seen them already.

Let's add a new "add-clone" subcommand to `git submodule--helper` with
the goal of converting part of the shell code in git-submodule.sh
related to `git submodule add` into C code. This new subcommand clones
the repository that is to be added, and checks out to the appropriate
branch.
This is meant to be a faithful conversion that leaves the behaviour of
'cmd_add()' script unchanged.

Separate out the core logic of module_clone() from the flag
parsing---this way we can call the equivalent of the `submodule--helper
clone` subcommand directly within C, without needing to push arguments
in a strvec.

The standard `die()` function that is used in C code prefixes all the
messages passed to it with 'fatal: '. This does not happen with the
`die` used in 'git-submodule.sh'.
Let's prefix each of the shell die messages with 'fatal: ' so that when
they are converted to C code, the error messages stay the same as before
the conversion.
Note that the shell version of `die` exits with error code 1, while the
C version exits with error code 128. In practice, this does not change
any behaviour, as no functionality in 'submodule add' and 'submodule
update' relies on the value of the exit code.

In general, we encourage users to use plumbing commands, like git
rev-list, over porcelain commands, like git log, when scripting.
However, git rev-list has one glaring problem that prevents it from
being used in certain cases: when --pretty is used with a custom format,
it always prints out a line containing "commit" and the object ID. This
makes it unsuitable for many scripting needs, and forces users to use
git log instead.
While we can't change this behavior for backwards compatibility, we can
add an option to suppress this behavior, so let's do so, and call it
"--no-commit-header". Additionally, add the corresponding positive
option to switch it back on.
Note that this option doesn't affect the built-in formats, only custom
formats. This is exactly the same behavior as users already have from
git log and is what most users will be used to.

Even when the `--allow-empty-message` option is given, "git commit"
offers an interactive editor session with prefilled message that says
the commit will be aborted if the buffer is emptied, which is wrong.
Remove the "an empty message aborts" part from the message when the
option is given to fix it.

In 0181b600a6 (pkt-line: define PACKET_READ_RESPONSE_END, 2020-05-19),
the Response End packet was defined for Git's network protocol. When the
patch was sent, it included an oversight where the error messages
referenced "stateless separator", the work-in-progress name, over
"response end", the final name chosen.
Correct these error messages by having them correctly reference
a "response end" packet.

When we cannot figure out how wide the terminal is, we use a
fallback value of 80 ourselves (which cannot be avoided), but when
we run the pager, we export it in COLUMNS, which forces the pager
to use the hardcoded value, even when the pager is perfectly
capable to figure it out itself. Stop exporting COLUMNS when we
fall back on the hardcoded default value for our own use.

This saves 8K per `struct object_directory', meaning it saves
around 800MB in my case involving 100K alternates (half or more
of those alternates are unlikely to hold loose objects).
This is implemented in two parts: a generic, allocation-free
`cbtree' and the `oidtree' wrapper on top of it. The latter
provides allocation using alloc_state as a memory pool to
improve locality and reduce free(3) overhead.
Unlike oid-array, the crit-bit tree does not require sorting.
Performance is bound by the key length, for oidtree that is
fixed at sizeof(struct object_id). There's no need to have
256 oidtrees to mitigate the O(n log n) overhead like we did
with oid-array.
Being a prefix trie, it is natively suited for expanding short
object IDs via prefix-limited iteration in
`find_short_object_filename'.
On my busy workstation, p4205 performance seems to be roughly
unchanged (+/-8%). Startup with 100K total alternates with no
loose objects seems around 10-20% faster on a hot cache.
(800MB in memory savings means more memory for the kernel FS
cache).
The generic cbtree implementation does impose some extra
overhead for oidtree in that it uses memcmp(3) on
"struct object_id" so it wastes cycles comparing 12 extra bytes
on SHA-1 repositories. I've not yet explored reducing this
overhead, but I expect there are many places in our code base
where we'd want to investigate this.
