tests(scalar): tighten the stale `scalar.repo` test some
As pointed out by Stolee, the previous incarnation of this test case was
not stringent enough: we want to verify that _only_ the stale entries
are removed (previously, the test case would have succeeded even if all
entries had been removed).
Let's rectify this and verify that the other entries are left intact.

scalar reconfigure -a: remove stale `scalar.repo` entries
Every once in a while, a Git for Windows installation fails because the
attempt to reconfigure a Scalar enlistment failed because it was deleted
manually without removing the corresponding entries in the global Git
config.
In f5f0842d0b5 (scalar: let 'unregister' handle a deleted enlistment
directory gracefully, 2021-12-03), we already taught `scalar delete` to
handle the case of a manually deleted enlistment gracefully. This patch
adds the same graceful handling to `scalar reconfigure --all`.
This patch is best viewed with `--color-moved`.

It is unclear as to _why_, but under certain circumstances the warning
about credentials being passed as part of the URL seems to be swallowed
by the `git remote-https` helper in the Windows jobs of Git's CI builds.
Since it is not actually important how many times Git prints the
warning/error message, as long as it prints it at least once, let's just
make the test a bit more lenient and test for the latter instead of the
former, which works around these CI issues.

t5516: move plaintext-password tests from t5601 and t5516
Commit 6dcbdc0d66 (remote: create fetch.credentialsInUrl config,
2022-06-06) added tests for our handling of passwords in URLs. Since the
obvious URL to be affected is git-over-http, the tests use http. However
they don't set up a test server; they just try to access
https://localhost, assuming it will fail (because the nothing is
listening there).
This causes some possible problems:
- There might be a web server running on localhost, and we do not
actually want to connect to that.
- The DNS resolver, or the local firewall, might take a substantial
amount of time (or forever, whichever comes first) to fail to
connect, slowing down the tests cases unnecessarily.
- Since there's no server, our tests for "allow" and "warn" still
expect the clone/fetch/push operations to fail, even though in the
real world we'd expect these to succeed. We scrape stderr to see
what happened, but it's not as robust as a more realistic test.
Let's instead move these to t5551, which is all about testing http and
where we have a real server. That eliminates any issues with contacting
a strange URL, and lets the "allow" and "warn" tests confirm that the
operation actually succeeds.
It's not quite a verbatim move for a few reasons:
- we can drop the LIBCURL dependency; it's already part of
lib-httpd.sh
- we'll use HTTPD_URL_USER_PASS, etc, instead of our fake URL. To
avoid repetition, we'll add a few extra variables.
- the "https://username:@localhost" test uses a funny URL that
lib-httpd.sh doesn't provide. We'll similarly construct it in a
variable. Note that we're hard-coding the lib-httpd username here,
but t5551 already does that everywhere.
- for the "domain:port" test, the URL provided by lib-httpd is fine,
since our test server will always be on an exotic port. But we'll
confirm in the test that this is so.
- since our message-matching is done via grep, I simplified it to use
a regex, rather than trying to massage lib-httpd's variables.
Arguably this makes it more readable, too, while retaining the bits
we care about: the fatal/warning distinction, the "uses plaintext"
message, and the fact that the password was redacted.
- we'll use the /auth/ path for the repo, which shows that we are
indeed making use of the auth information when needed.
- we'll also use /smart/; most of these tests could be done via /dumb/
in t5550, but setting up pushes there requires extra effort and
dependencies. The smart protocol is what most everyone is using
these days anyway.
This patch is my own, but I stole the analysis and a few bits of the
commit message from a patch by Johannes Schindelin.

apply: reject patches larger than ~1 GiB
The apply code is not prepared to handle extremely large files. It uses
"int" in some places, and "unsigned long" in others.
This combination leads to unfortunate problems when switching between
the two types. Using "int" prevents us from handling large files, since
large offsets will wrap around and spill into small negative values,
which can result in wrong behavior (like accessing the patch buffer with
a negative offset).
Converting from "unsigned long" to "int" also has truncation problems
even on LLP64 platforms where "long" is the same size as "int", since
the former is unsigned but the latter is not.
To avoid potential overflow and truncation issues in `git apply`, apply
similar treatment as in dcd1742e56 (xdiff: reject files larger than
~1GB, 2015-09-24), where the xdiff code was taught to reject large
files for similar reasons.
The maximum size was chosen somewhat arbitrarily, but picking a value
just shy of a gigabyte allows us to double it without overflowing 2^31-1
(after which point our value would wrap around to a negative number).
To give ourselves a bit of extra margin, the maximum patch size is a MiB
smaller than a full GiB, which gives us some slop in case we allocate
"(records + 1) * sizeof(int)" or similar.
Luckily, the security implications of these conversion issues are
relatively uninteresting, because a victim needs to be convinced to
apply a malicious patch.

builtin: patch-id: fix patch-id with binary diffs
"git patch-id" currently doesn't produce correct output if the
incoming diff has any binary files. Add logic to get_one_patchid
to handle the different possible styles of binary diff. This
attempts to keep resulting patch-ids identical to what would be
produced by the counterpart logic in diff.c, that is it produces
the id by hashing the a and b oids in succession.
In general we handle binary diffs by first caching the object ids from
the "index" line and using those if we then find an indication
that the diff is binary.
The input could contain patches generated with "git diff --binary". This
currently breaks the parse logic and results in multiple patch-ids
output for a single commit. Here we have to skip the contents of the
patch itself since those do not go into the patch id. --binary
implies --full-index so the object ids are always available.
When the diff is generated with --full-index there is no patch content
to skip over.
When a diff is generated without --full-index or --binary, it will

unique patch-id when hashed, but does not match internal patch id
output. We'll call this ok for now as we already need specialized
arguments to diff in order to match internal patch id (namely -U3).

patch-id: use stable patch-id for rebases
Git doesn't persist patch-ids during the rebase process, so there is
no need to specifically invoke the unstable variant. Use the stable
logic for all internal patch-id calculations to minimize the number of
code paths and improve test coverage.

patch-id: fix stable patch id for binary / header-only
Patch-ids for binary patches are found by hashing the object
ids of the before and after objects in succession. However in
the --stable case, there is a bug where hunks are not flushed
for binary and header-only patch ids, which would always result
in a patch-id of 0000. The --unstable case is currently correct.
Reorder the logic to branch into 3 cases for populating the
patch body: header-only which populates nothing, binary which
populates the object ids, and normal which populates the text
diff. All branches will end up flushing the hunk.
Don't populate the ---a/ and +++b/ lines for binary diffs, to correspond
to those lines not being present in the "git diff" text output.
This is necessary because we advertise that the patch-id calculated
internally and used in format-patch is the same that what the
builtin "git patch-id" would produce when piped from a diff.
Update the test to run on both binary and normal files.

shortlog: implement `--group=author` in terms of `--group=<format>`
Instead of handling SHORTLOG_GROUP_AUTHOR separately, reimplement it as
a special case of the new `--group=<format>` mode, where the author mode
is a shorthand for `--group='%aN <%aE>'.
Note that we still need to keep the SHORTLOG_GROUP_AUTHOR enum since it
has a different meaning in `read_from_stdin()`, where it is still used
for a different purpose.

shortlog: extract `shortlog_finish_setup()`
Extract a function which finishes setting up the shortlog struct for
use. The caller in `make_cover_letter()` does not care about trailer
sorting, so it isn't strictly necessary to add a call there in this
patch.
But the next patch will add additional functionality to the new
`shortlog_finish_setup()` function, which the caller in
`make_cover_letter()` will care about.

shortlog: support arbitrary commit format `--group`s
In addition to generating a shortlog based on committer, author, or the
identity in one or more specified trailers, it can be useful to generate
a shortlog based on an arbitrary commit format.
This can be used, for example, to generate a distribution of commit
activity over time, like so:
Arbitrary commit formats can be used. In fact, `git shortlog`'s default
behavior (to count by commit authors) can be emulated as follows:
$ git shortlog --group='%aN <%aE>' ...
and future patches will make the default behavior (as well as
`--committer`, and `--group=trailer:<trailer>`) special cases of the
more flexible `--group` option.
Note also that the SHORTLOG_GROUP_FORMAT enum value is used only to
designate that `--group:<format>` is in use when in stdin mode to
declare that the combination is invalid.
