While both git-rev-list(1) and git-log(1) support `--stdin`, it only
accepts commits and files. Most notably, it is impossible to pass any of
the pseudo-opts like `--all`, `--glob=` or others via stdin.
This makes it hard to use this function in certain scripted scenarios,
like when one wants to support queries against specific revisions, but
also against reference patterns. While this is theoretically possible by
using arguments, this may run into issues once we hit platform limits
with sufficiently large queries. And because `--stdin` cannot handle
pseudo-opts, the only alternative would be to use a mixture of arguments
and standard input, which is cumbersome.
Implement support for handling pseudo-opts in both commands to support
this usecase better. One notable restriction here is that `--stdin` only
supports "stuck" arguments in the form of `--glob=foo`. This is because
"unstuck" arguments would also require us to read the next line, which
would add quite some complexity to the code. This restriction should be
fine for scripted usage though.

revision: small readability improvement for reading from stdin
The code that reads lines from standard input manually compares whether
the read line matches "--", which is a bit awkward to read. Furthermore,
we're about to extend the code to also support reading pseudo-options
via standard input, requiring more elaborate handling of lines with a
leading dash.
Refactor the code by hoisting out the check for "--" outside of the
block that checks for a leading dash.

format-patch: free elements of rev.ref_message_ids list
When we are showing multiple patches with format-patch, we have to
repeatedly overwrite the rev.message_id field. We take care to avoid
leaking the old value by either freeing it, or adding it to
ref_message_ids, a string list of ids to reference in subsequent
messages.
But unfortunately we do leak the value via that string list. We try
to clear the string list, courtesy of 89f45cf4eb (format-patch: don't
leak "extra_headers" or "ref_message_ids", 2022-04-13). But since it was
initialized as "nodup", the string list doesn't realize it owns the
strings, and it leaks them.
We have two options here:
1. Continue to init with "nodup", but then tweak the value of
ref_message_ids.strdup_strings just before clearing.
2. Init with "dup", but use "append_nodup" when transferring ownership
of strings to the list. Clearing just works.
I picked the second here, as I think it calls attention to the tricky
part (transferring ownership via the nodup call).
There's one other related fix we have to do, though. We also insert the
result of clean_message_id() into the list. This _sometimes_ allocates
and sometimes does not, depending on whether we have to remove cruft
from the end of the string. Let's teach it to consistently return an
allocated string, so that the caller knows it must be freed.
There's no new test here, as the leak can already be seen in t4014.44 (as
well as others in that script). We can't mark all of t4014 as leak-free,
though, as there are other unrelated leaks that it triggers.

t/lib-httpd: make CGIPassAuth support conditional
Commit 988aad99b4 (t5563: add tests for basic and anoymous HTTP access,
2023-02-27) added tests that require Apache to support the CGIPassAuth
directive, which was added in Apache 2.4.13. This is fairly old (~8
years), but recent enough that we still encounter it in the wild (e.g.,
RHEL/CentOS 7, which is not EOL until June 2024).
We can live with skipping the new tests on such a platform. But
unfortunately, since the directive is used unconditionally in our
apache.conf, it means the web server fails to start entirely, and we
cannot run other HTTP tests at all (e.g., the basic ones in t5551).
We can fix that by making the config conditional, and only triggering it
for t5563. That solves the problem for t5551 (which then ignores the
directive entirely). For t5563, we'd see apache complain in start_httpd;
with the default setting of GIT_TEST_HTTPD, we'd then skip the whole
script.
But that leaves one small problem: people may set GIT_TEST_HTTPD=1
explicitly, which instructs the tests to fail (rather than skip) when we
can't start the webserver (to avoid accidentally missing some tests).
This could be worked around by having the user manually set
GIT_SKIP_TESTS on a platform with an older Apache. But we can be a bit
friendlier by doing the version check ourselves and setting an
appropriate prereq. We'll use the (lack of) prereq to then skip the rest
of t5563. In theory we could use the prereq to skip individual tests, but
in practice this whole script depends on it.

2. The second index access point is involved in rename detection,

upload-pack: advertise capabilities when cloning empty repos
When cloning an empty repository, protocol versions 0 and 1 currently
offer nothing but the header and flush packets for the /info/refs
endpoint. This means that no capabilities are provided, so the client
side doesn't know what capabilities are present.
However, this does pose a problem when working with SHA-256
repositories, since we use the capabilities to know the remote side's
object format (hash algorithm). As of 8b214c2e9d ("clone: propagate
object-format when cloning from void", 2023-04-05), this has been fixed
for protocol v2, since there we always read the hash algorithm from the
remote.
Fortunately, the push version of the protocol already indicates a clue
for how to solve this. When the /info/refs endpoint is accessed for a
push and the remote is empty, we include a dummy "capabilities^{}" ref
pointing to the all-zeros object ID. The protocol documentation already
indicates this should _always_ be sent, even for fetches and clones, so
let's just do that, which means we'll properly announce the hash
algorithm as part of the capabilities. This just works with the
existing code because we share the same ref code for fetches and clones,
and libgit2, JGit, and dulwich do as well.
There is one minor issue to fix, though. If we called send_ref with
namespaces, we would return NULL with the capabilities entry, which
would cause a crash. Instead, let's refactor out a function to print
just the ref itself without stripping the namespace and use it for our
special capabilities entry.
Add several sets of tests for HTTP as well as for local clones. The
behavior can be slightly different for HTTP versus a local or SSH clone
because of the stateless-rpc functionality, so it's worth testing both.

Use test_path_is_missing instead, which is a more appropriate helper.

rebase -r: fix the total number shown in the progress
For regular, non-`--rebase-merges` runs, there is very little work to do
for the parser when determining the total number of commands in a rebase
script: it is simply the number of lines after stripping the commented
lines and then trimming the trailing empty line, if any.
The `--rebase-merges` mode complicates things by introducing empty lines
and comments in the middle of the script. These should _not_ be counted
as commands, and indeed, when an interactive rebase is interrupted and
subsequently resumed, the total number of commands can magically shrink,
sometimes dramatically.
The reason for this strange behavior is that empty lines _are_ counted
in `edit_todo_list()` (but not the comments, as they are stripped via
`strbuf_stripspace(..., 1)`, which is a bug.
Let's fix this so that the correct total number is shown from the
get-go, by carefully adjusting it according to what's in the rebase
script. Extra care needs to be taken in case the user edits the script:
the number of commands might be different after the user edited than
beforehand.
Note: Even though commented lines are skipped in `edit_todo_list()`, we
still need to handle `TODO_COMMENT` items by decrementing the
already-incremented `total_nr` again: empty lines are also marked as
`TODO_COMMENT`.

The `total_nr` field in the `todo_list` structure merely serves display
purposes, and should only be used when generating the progress message.
In these two instances, however, we want to loop over all of the
commands in the parsed rebase script. The loop limit therefore needs to
be `nr`, which refers to the count of commands in the current
`todo_list`.
This is important because the two numbers, `nr` and `total_nr` can
differ wildly, e.g. due to `total_nr` _not_ counting comments or empty
lines, while `nr` skips any commands that already moved from the
`git-rebase-todo` file to the `done` file.

pack-refs: teach pack-refs --include option
Allow users to be more selective over which refs to pack by adding an
--include option to git-pack-refs.
The existing options allow some measure of selectivity. By default
git-pack-refs packs all tags. --all can be used to include all refs,
and the previous commit added the ability to exclude certain refs with
--exclude.
While these knobs give the user some selection over which refs to pack,
it could be useful to give more control. For instance, a repository may
have a set of branches that are rarely updated and would benefit from
being packed. --include would allow the user to easily include a set of
branches to be packed while leaving everything else unpacked.

pack-refs: teach --exclude option to exclude refs from being packed
At GitLab, we have a system that creates ephemeral internal refs that
don't live long before getting deleted. Having an option to exclude
certain refs from a packed-refs file allows these internal references to
be deleted much more efficiently.
Add an --exclude option to the pack-refs builtin, and use the ref
exclusions API to exclude certain refs from being packed into the final
packed-refs file
