reflog_expiry_prepare() calls mark_reachable(), which recurively flags
commits as REACHABLE. The traversal stops beyond a certain age
threshold; the boundary commits also marked as REACHABLE and put back
into mark_list at the end. unreachable() finishes the traversal down to
the roots if necessary -- but if all interesting commits are younger
than the age threshold then only recent commits need to be visited.
When this optimization works then the boundary commits still sit there
in mark_list at the end. Clear their REACHABLE flag and release the
commit list allocations.
While at it remove a duplicate code line from mark_reachable(); the same
flag is already set five lines up.

The logic to handle worktree refs (worktrees/NAME/REF and
main-worktree/REF) existed in two places:
* ref_type() in refs.c
* parse_worktree_ref() in worktree.c
Collapse this logic together in one function parse_worktree_ref():
this avoids having to cross-check the result of parse_worktree_ref()
and ref_type().
Introduce enum ref_worktree_type, which is slightly different from
enum ref_type. The latter is a misleading name (one would think that
'ref_type' would have the symref option).
Instead, enum ref_worktree_type only makes explicit how a refname
relates to a worktree. From this point of view, HEAD and
refs/bisect/abc are the same: they specify the current worktree
implicitly.
The files-backend must avoid packing refs/bisect/* and friends into
packed-refs, so expose is_per_worktree_ref() separately.

As reported in [1] the "UNUSED(var)" macro introduced in
2174b8c75de (Merge branch 'jk/unused-annotation' into next,
2022-08-24) breaks coccinelle's parsing of our sources in files where
it occurs.
Let's instead partially go with the approach suggested in [2] of
making this not take an argument. As noted in [1] "coccinelle" will
ignore such tokens in argument lists that it doesn't know about, and
it's less of a surprise to syntax highlighters.
This undoes the "help us notice when a parameter marked as unused is
actually use" part of 9b24034754 (git-compat-util: add UNUSED macro,
2022-08-19), a subsequent commit will further tweak the macro to
implement a replacement for that functionality.

Functions used with for_each_reflog_ent() need to conform to a
particular interface, but not every function needs all of the
parameters. Mark the unused ones to make -Wunused-parameter happy.

each_ref_fn interface. But most of them don't need every parameter;
let's annotate the unused ones to quiet -Wunused-parameter.

"git reflog" command now uses parse-options API to parse its
command line options.
* ab/reflog-parse-options:
reflog: fix 'show' subcommand's argv
reflog [show]: display sensible -h output
reflog: convert to parse_options() API
reflog exists: use parse_options() API
git reflog [expire|delete]: make -h output consistent with SYNOPSIS
reflog: move "usage" variables and use macros
reflog tests: add missing "git reflog exists" tests
reflog: refactor cmd_reflog() to "if" branches
reflog.c: indent argument lists
When reflog.c was lib-ified in 7d3d226e70 (reflog: libify delete
reflog function and helpers, 2022-03-02) these previously "static"
functions were made non-"static", but the argument lists were not
correspondingly indented according to our usual coding style. Let's do
that.

Currently stash shells out to reflog in order to delete refs. In an
effort to reduce how much we shell out to a subprocess, libify the
functionality that stash needs into reflog.c.
Add a reflog_delete function that is pretty much the logic in the while
loop in builtin/reflog.c cmd_reflog_delete(). This is a function that
builtin/reflog.c and builtin/stash.c can both call.
Also move functions needed by reflog_delete and export them.
