We have a virtual pickaxe_fn for handling -G versus -S pickaxe options.
They need to take the same set of parameters, but of course they care
about different ones (e.g., a regex -G will never use a kwset).
Mark the unused ones to appease -Wunused-parameter.

The null stream filter unsurprisingly does not look at its "filter"
argument, since it just eats bytes. But we can't drop it, since it has
to conform to the same virtual interface that real filters do. Mark the
unused parameter to appease -Wunused-parameter.

We squelch error/warning output by passing a noop handler to

so that it doesn't trigger -Wunused-parameter.

In parse_git_diff_header(), we have a table-driven parser that maps
strings to handler functions. Not all handlers need all of the
parameters; let's mark the unused ones to appease -Wunused-parameter.

When parsing approxidates, we use a table to map special strings (like
"noon") to functions which handle them. Not all functions need the "now"
parameter, as they are not relative (e.g., "yesterday" does, but "pm"
does not). Let's annotate those to make -Wunused-parameter happy.

String-lists may be used with callbacks for clearing or iteration. These
callbacks need to conform to a particular interface, even though not
every callback needs all of its parameters. Mark the unused ones to make

The 0'th entry of our hash_algos array fills out the virtual methods
with a series of functions which simply BUG(). This is the right thing
to do, since the point is to catch use of an invalid algo parameter, but
we need to annotate them to appease -Wunused-parameters.

When a platform feature isn't available or in use, we sometimes
conditionally compile empty or trivial functions to turn these into
noops. We need to annotate their parameters so that -Wunused-parameters
won't complain about them.
Note that there are many more of these in compat/mingw.h, but we'll
leave them for now, as there's some trickery required to get the UNUSED
macro available there.

The parse-options callback for --again soaks up all remaining options by
manipulating the parse_opt_ctx's argc and argv fields. Even though it
has to look at both, the actual parsing happens via the do_reupdate()
helper, which only looks at the argv half (by passing it along to
parse_pathspec). So that helper doesn't need to see argc at all.
Note that the helper does look at "argv + 1" without confirming that
argc is greater than 0. We know this is correct because it is skipping
past the actual "--again" string, which will always be present. However,
to make what's going on more obvious, let's move that "+1" into the
caller, which has the matching "-1" when fixing up the ctx's argc/argv.

The module_list_compute() function takes an argc/argv pair, but never
looks at argc. This is OK, as the NULL terminator in argv is sufficient
for our purposes (we feed it to parse_pathspec(), which takes only the
array, not a count).
Note that one of the callers _looks_ like it would be buggy, but isn't:
we pass 0/NULL for argc/argv from module_foreach(), so finding the
terminating NULL in that argv naively would segfault. However,
parse_pathspec() is smart enough to interpret a bare NULL as an empty
argv.

The callback interface for xdiff_emit_line_fn gives us a line/len pair,
but diffstat_consume() never looks at "len". At first glance this seems
like a bug that could cause us to read further than xdiff intends. But
in practice, we read only the first character, and xdiff would never
pass us an empty line.
Let's add a run-time assertion that this is true, which clarifies our
assumption and silences -Wunused-parameter.

The trace2 region around the call to lazy_bitmap_for_commit() in
bitmap_for_commit() was added in 28cd730680d (pack-bitmap: prepare to
read lookup table extension, 2022-08-14). While adding trace2 regions is
typically helpful for tracking performance, this method is called
possibly thousands of times as a commit walk explores commit history
looking for a matching bitmap. When trace2 output is enabled, this
region is emitted many times and performance is throttled by that
output.
For now, remove these regions entirely.
This is a critical path, and it would be valuable to measure that the
time spent in bitmap_for_commit() does not increase when using the
commit lookup table. The best way to do that would be to use a mechanism
that sums the time spent in a region and reports a single value at the
end of the process. This technique was introduced but not merged by [1]
so maybe this example presents some justification to revisit that
approach.

To help with the 'git blame' output in this region, add a comment that
warns against adding a trace2 region. Delete a test from t5310 that used
that trace output to check that this lookup optimization was activated.
To create this kind of test again in the future, the stopwatch traces
mentioned earlier could be used as a signal that we activated this code
path.

We attribute each documentation text file to a man section by finding a
line in the file that looks like "gitfoo(<digit>)". Commit cc75e556a9
("scalar: add to 'git help -a' command list", 2022-09-02) updated this
logic to look not only for "gitfoo" but also "scalarfoo". In doing so,
it forgot to account for the fact that after the updated regex has found
a match, the man section is no longer to be found in `$1` but now lives
in `$2`.
This makes our git(1) manpage look as follows:
Main porcelain commands
git-add(git)
Add file contents to the index.
[...]
gitk(git)
The Git repository browser.
scalar(scalar)
A tool for managing large Git repositories.
Restore the man sections by not capturing the (git|scalar) part of the
match into `$1`.
As noted by Ævar [1], we could even match any "foo" rather than just
"gitfoo" and "scalarfoo", but that's a larger change. For now, just fix
the regression in cc75e556a9.
