Now that the default value for TEST_PASSES_SANITIZE_LEAK is `true` there
is no longer a need to have that variable declared in all of our tests.
Drop it.

Commit 852a171018 (am: let command-line options override saved options,
2015-08-04) redirected a few "git am" invocations from /dev/zero, even
though it did not expect "am" to read the input. This was necessary at
the time because those tests used test_terminal, and as described in
18d8c26930 (test_terminal: redirect child process' stdin to a pty,
2015-08-04):
Note that due to the way the code is structured, the child's stdin
pseudo-tty will be closed when we finish reading from our stdin. This
means that in the common case, where our stdin is attached to /dev/null,
the child's stdin pseudo-tty will be closed immediately. Some operations
like isatty(), which git-am uses, require the file descriptor to be
open, and hence if the success of the command depends on such functions,
test_terminal's stdin should be redirected to a source with large amount
of data to ensure that the child's stdin is not closed, e.g.
test_terminal git am --3way </dev/zero
But we later dropped the use of test_terminal in 53ce2e3f0a (am: add
explicit "--retry" option, 2024-06-06). That commit dropped one of the
redirections from /dev/zero but not the other.
In theory the remaining one should not cause any problems, but it turns
out that at least one platform (NonStop) does not have /dev/zero at all.
We never noticed before because it also did not pass the TTY prereq,
meaning these tests were not run at all there until 53ce2e3f0a.
So let's drop the useless /dev/zero mention. There are others in the
test suite, but they are run only for tests marked with EXPENSIVE (so
not typically by default).

When computing rename conflicts in our recursive merge algorithm we set
up `struct rename_conflict_info`s to track that information. We never
free those data structures though and thus leak memory.
We need to be a bit more careful here though because the same rename
conflict info can be assigned to multiple structures. Accommodate for
this by introducing a `rename_conflict_info_owned` bit that we can use
to steer whether or not the rename conflict info shall be free'd.

After a patch fails, you can ask "git am" to try applying it again with
new options by running without any of the resume options. E.g.:
git am <patch
# oops, it failed; let's try again
git am --3way
But since this second command has no explicit resume option (like
"--continue"), it looks just like an invocation to read a fresh patch
from stdin. To avoid confusing the two cases, there are some heuristics,
courtesy of 8d18550318 (builtin-am: reject patches when there's a
session in progress, 2015-08-04):
if (in_progress) {
/*
* Catch user error to feed us patches when there is a session
* in progress:
*
* 1. mbox path(s) are provided on the command-line.
* 2. stdin is not a tty: the user is trying to feed us a patch
* from standard input. This is somewhat unreliable -- stdin
* could be /dev/null for example and the caller did not
* intend to feed us a patch but wanted to continue
* unattended.
*/
if (argc || (resume_mode == RESUME_FALSE && !isatty(0)))
die(_("previous rebase directory %s still exists but mbox given."),
state.dir);
if (resume_mode == RESUME_FALSE)
resume_mode = RESUME_APPLY;
[...]
So if no resume command is given, then we require that stdin be a tty,
and otherwise complain about (potentially) receiving an mbox on stdin.
But of course you might not actually have a terminal available! And
sadly there is no explicit way to hit this same code path; this is the
only place that sets RESUME_APPLY. So you're stuck, and scripts like our
test suite have to bend over backwards to create a pseudo-tty.
Let's provide an explicit option to trigger this mode. The code turns
out to be quite simple; just setting "resume_mode" to RESUME_FALSE is
enough to dodge the tty check, and then our state is the same as it
would be with the heuristic case (which we'll continue to allow).
When we don't have a session in progress, there's already code to
complain when resume_mode is set (but we'll add a new test to cover
that).
To test the new option, we'll convert the existing tests that rely on
the fake stdin tty. That lets us test them on more platforms, and will
let us simplify test_terminal a bit in a future patch.
It does, however, mean we're not testing the tty heuristic at all.

They are equivalents and the former still exists, so as long as the
only change this commit makes are to rewrite test_i18ngrep to
test_grep, there won't be any new bug, even if there still are
callers of test_i18ngrep remaining in the tree, or when merged to
other topics that add new uses of test_i18ngrep.
This patch was produced more or less with
git grep -l -e 'test_i18ngrep ' 't/t[0-9][0-9][0-9][0-9]-*.sh' |
xargs perl -p -i -e 's/test_i18ngrep /test_grep /'
and a good way to sanity check the result yourself is to run the
above in a checkout of c4603c1c (test framework: further deprecate
test_i18ngrep, 2023-10-31) and compare the resulting working tree
contents with the result of applying this patch to the same commit.
You'll see that test_i18ngrep in a few t/lib-*.sh files corrected,
in addition to the manual reproduction.

As a follow-up to d162b25f956 (tests: remove support for
GIT_TEST_GETTEXT_POISON, 2021-01-20) remove most uses of test_i18ncmp
via a simple s/test_i18ncmp/test_cmp/g search-replacement.
I'm leaving t6300-for-each-ref.sh out due to a conflict with in-flight
changes between "master" and "seen", as well as the prerequisite
itself due to other changes between "master" and "next/seen" which add
new test_i18ncmp uses.

The function test_i18ngrep fakes success when run under GETTEXT_POISON.
Hence, running in the following manner will always fail under gettext
poison:

Use correct syntax: test_i18ngrep ! expected actual

After resolving a conflicting patch, a user may wish to sign off the
patch to declare that the patch has been modified. As such, the user
will expect that running "git am --signoff --continue" will append the
signoff to the commit message.
However, the --signoff option is only taken into account during the
mail-parsing stage. If the --signoff option is set, then the signoff
will be appended to the commit message. Since the mail-parsing stage
comes before the patch application stage, the --signoff option, if
provided on the command-line when resuming, will have no effect at all.
We cannot move the append_signoff() call to the patch application stage
as the applypatch-msg hook and interactive mode, which run before patch
application, may expect the signoff to be there.
Fix this by taking note if the user explictly set the --signoff option
on the command-line, and append the signoff to the commit message when
resuming if so.

When resuming, git-am mistakenly ignores command-line options.
For instance, when a patch fails to apply with "git am patch",
subsequently running "git am --3way" would not cause git-am to fall
back on attempting a threeway merge. This occurs because by default
the --3way option is saved as "false", and the saved am options are
loaded after the command-line options are parsed, thus overwriting
the command-line options when resuming.
Fix this by moving the am_load() function call before parse_options(),
so that command-line options will override the saved am options.
The purpose of supporting this use case is to enable users to "wiggle"
that one conflicting patch. As such, it is expected that the
command-line options do not affect subsequent applied patches. Implement
this by calling am_load() once we apply the conflicting patch
successfully.
