When rebasing with "--signoff" the commit created by "rebase --continue"
after resolving conflicts or editing a commit fails to add the
"Signed-off-by:" trailer. This happens because the message from the
original commit is reused instead of the one that would have been used
if the sequencer had not stopped for the user interaction. The correct
message is stored in ctx->message and so with a couple of exceptions
this is written to rebase_path_message() when stopping for user
interaction instead. The exceptions are (i) "fixup" and "squash"
commands where the file is written by error_failed_squash() and (ii)
"edit" commands that are fast-forwarded where the original message is
still reused. The latter is safe because "--signoff" will never
fast-forward.
Note this introduces a change in behavior as the message file now
contains conflict comments. This is safe because commit_staged_changes()
passes an explicit cleanup flag when not editing the message and when
the message is being edited it will be cleaned up automatically. This
means user now sees the same message comments in editor with "rebase
--continue" as they would if they ran "git commit" themselves before
continuing the rebase. It also matches the behavior of "git
cherry-pick", "git merge" etc. which all list the files with merge
conflicts.
The tests are extended to check that all commits made after continuing a
rebase have a "Signed-off-by:" trailer. Sadly there are a couple of
leaks in apply.c which I've not been able to track down that mean this
test file is no-longer leak free when testing "git rebase --apply
--signoff" with conflicts.

This test file assumes the "apply" backend is the default which is not
the case since 2ac0d6273f (rebase: change the default backend from "am"
to "merge", 2020-02-15). Make sure the "apply" backend is tested by
specifying it explicitly.

Using a helper function makes the tests shorter and avoids running "git
cat-file" upstream of a pipe.

Perform the setup in a dedicated test so the later tests can be run
independently. Also avoid running git upstream of a pipe and take
advantage of test_commit.

Fix various leaks in built-ins, libraries and a test helper here we
were missing a call to strbuf_release(), string_list_clear() etc, or
were calling them after a potential "return".
Comments on individual changes:
- builtin/checkout.c: Fix a memory leak that was introduced in [1]. A
sibling leak introduced in [2] was recently fixed in [3]. As with [3]
we should be using the wt_status_state_free_buffers() API introduced
in [4].
- builtin/repack.c: Fix a leak that's been here since this use of
"strbuf_release()" was added in a1bbc6c017 (repack: rewrite the shell
script in C, 2013-09-15). We don't use the variable for anything
except this loop, so we can instead free it right afterwards.
- builtin/rev-parse: Fix a leak that's been here since this code was
added in 21d4783538 (Add a parseopt mode to git-rev-parse to bring
parse-options to shell scripts., 2007-11-04).
- builtin/stash.c: Fix a couple of leaks that have been here since
this code was added in d4788af875 (stash: convert create to builtin,
2019-02-25), we strbuf_release()'d only some of the "struct strbuf" we
allocated earlier in the function, let's release all of them.
- ref-filter.c: Fix a leak in 482c119186 (gpg-interface: improve
interface for parsing tags, 2021-02-11), we don't use the "payload"
variable that we ask parse_signature() to populate for us, so let's
free it.
- t/helper/test-fake-ssh.c: Fix a leak that's been here since this
code was added in 3064d5a38c (mingw: fix t5601-clone.sh,
2016-01-27). Let's free the "struct strbuf" as soon as we don't need
it anymore.

Allow --signoff to be used with --interactive and --merge. In
interactive mode only commits marked to be picked, edited or reworded
will be signed off.
The main motivation for this patch was to allow one to run 'git rebase
--exec "make check" --signoff' which is useful when preparing a patch
series for publication and is more convenient than doing the signoff
with another --exec command.
This change also allows --root without --onto to work with --signoff
as well (--root with --onto was already supported).
