Change a couple of uses of "test_expect_failure" to use a
"test_expect_success" to positively assert the current behavior, and
replace the intent of "test_expect_failure" with a "TODO" comment int
the description.
As noted in [1] the "test_expect_failure" feature is overly eager to
accept any failure as OK, and thus by design hides segfaults, abort()
etc. Because of that I didn't notice in dd9cede9136 (leak tests: mark
some rev-list tests as passing with SANITIZE=leak, 2021-10-31) that
this test leaks memory under SANITIZE=leak.
I have some larger local changes to add a better
"test_expect_failure", which would work just like
"test_expect_success", but would allow us say "test_todo" here (and
"success" would emit a "not ok [...] # TODO", not "ok [...]".
So even though using "test_expect_success" here comes with its own
problems[2], let's use it as a narrow change to fix the problem at
hand here and stop conflating the current "success" with actual
SANITIZE=leak failures.

Change a fragile pattern introduced in 2b459b483cb (diff: make sure
work tree side is shown as 0{40} when different, 2008-03-02) to check
the exit code of "git rev-list", while we're at it let's get rid of
the needless sub-shell for invoking it in favor of the "-C" option.
Because of this I'd marked these tests as passing under SANITIZE=leak
in 16d4bd4f14e (leak tests: mark some diff tests as passing with
SANITIZE=leak, 2021-10-31), let's remove the
"TEST_PASSES_SANITIZE_LEAK=true" annotation as they no longer do.

Change a fragile test pattern that's been with us ever since these
tests were introduced in [1], [2] and [3] to properly return the exit
code of the failing command on failure.
Because of this I'd marked this test as passing under SANITIZE=leak in
[4] and [5]. We need to remove those annotations as these tests will
no longer pass.

Amend a test added in 9c46c054ae4 (rev-parse: tests git rev-parse
--verify master@{n}, for various n, 2010-08-24) so that we'll stop
ignoring the exit code of "git reflog" by having it on the
left-hand-side of a pipe.
Because of this I'd marked this test as passing under SANITIZE=leak in
f442c94638d (leak tests: mark some rev-parse tests as passing with
SANITIZE=leak, 2021-10-31). As all of it except this specific test
will now pass, let's skip it under the !SANITIZE_LEAK prerequisite.

As in the preceding commit change a similar fragile test pattern
introduced in b798671fa93 (merge-recursive: do not rudely die on
binary merge, 2007-08-14) to use a "test_must_fail" instead.
Before this we wouldn't distinguish normal "git merge" failures from
segfaults or abort(). Unlike the preceding commit we didn't end up
hiding any SANITIZE=leak failures in this case, but let's
correspondingly change these anyway.

Fix a test pattern that originated in f1af60bdba4 (Support 'diff=pgm'
attribute, 2007-04-22) so that we'll stop using "git diff" on the
left-hand-side of a pipe, and thus ignoring its exit code.
Rather than use intermediate files let's rewrite these tests to a much
simpler but more exhaustive "test_tmp" where we'll ignore certain
fields in the output.
Note that this is not a faithful conversion of the previous
"read/test" in some cases, as we were ignoring more fields there than
we strictly needed to. Now we'll "test_cmp" everything we can, and
only ignore the likes of paths to $TEMPDIR etc.

Fix an issue with the exit code of "diff-files" being ignored, which
has been ignored ever since these tests were originally added in
c859600954d ([PATCH] read-tree: save more user hassles during
fast-forward., 2005-06-07).
Since the exit code was ignored we'd hide errors here under
SANITIZE=leak, which resulted in me mistakenly marking these tests as
passing under SANITIZE=leak in e5a917fcf42 (unpack-trees: don't leak
memory in verify_clean_subdirectory(), 2021-10-07) and
4ea08416b8e (leak tests: mark a read-tree test as passing
SANITIZE=leak, 2021-10-31).
As it would be non-trivial to fix these tests (the leak is in
revision.c) let's un-mark them as passing under SANITIZE=leak in
addition to fixing the issue of ignoring the exit code.

cdff1bb5a3d (test-lib-functions: introduce test_stdout_line_count,
2021-07-04) so that we'll spot if git itself dies, segfaults etc in
these expressions.
Because we didn't distinguish these failure conditions before I'd
mistakenly marked these tests as passing under SANITIZE=leak in
dd9cede9136 (leak tests: mark some rev-list tests as passing with
SANITIZE=leak, 2021-10-31).

Change some of the patterns in the test suite where we were hiding the
exit code from "git" by invoking it in a sub-shell within a "test"
expression to use temporary files and test_cmp instead.
These are not all the occurrences of this anti-pattern, but these in
particular hid issues where LSAN was dying, and I'd thus marked these
tests as passing under the linux-leaks CI job in past commits with
"TEST_PASSES_SANITIZE_LEAK=true". Let's deal with that by either
removing that marking, or skipping specific tests under
!SANITIZE_LEAK.

Fix a memory leak in the parse_date_format() function by providing a
new date_mode_release() companion function.
By using this in "t/helper/test-date.c" we can mark the
"t0006-date.sh" test as passing when git is compiled with
SANITIZE=leak, and whitelist it to run under
"GIT_TEST_PASSING_SANITIZE_LEAK=true" by adding
"TEST_PASSES_SANITIZE_LEAK=true" to the test itself.
The other tests that expose this memory leak (i.e. take the
"mode->type == DATE_STRFTIME" branch in parse_date_format()) are
"t6300-for-each-ref.sh" and "t7004-tag.sh". The former is due to an
easily fixed leak in "ref-filter.c", and brings the failures in
"t6300-for-each-ref.sh" down from 51 to 48.
Fixing the remaining leaks will have to wait until there's a
release_revisions() in "revision.c", as they have to do with leaks via
"struct rev_info".
There is also a leak in "builtin/blame.c" due to its call to
parse_date_format() to parse the "blame.date" configuration. However
as it declares a file-level "static struct date_mode blame_date_mode"
to track the data, LSAN will not report it as a leak. It's possible to
get valgrind(1) to complain about it with e.g.:
valgrind --leak-check=full --show-leak-kinds=all ./git -P -c blame.date=format:%Y blame README.md
But let's focus on things LSAN complains about, and are thus
observable with "TEST_PASSES_SANITIZE_LEAK=true". We should get to
fixing memory leaks in "builtin/blame.c", but as doing so would
require some re-arrangement of cmd_blame() let's leave it for some
other time.

Provide and use a DATE_MODE_INIT macro. Most of the users of struct
date_mode" use it via pretty.h's "struct pretty_print_context" which
doesn't have an initialization macro, so we're still bound to being
initialized to "{ 0 }" by default.
But we can change the couple of callers that directly declared a
variable on the stack to instead use the initializer, and thus do away
with the "mode.local = 0" added in add00ba2de9 (date: make "local"
orthogonal to date format, 2015-09-03).

Move the declaration of the date.c functions from cache.h, and adjust
the relevant users to include the new date.h header.
The show_ident_date() function belonged in pretty.h (it's defined in
pretty.c), its two users outside of pretty.c didn't strictly need to
include pretty.h, as they get it indirectly, but let's add it to them
anyway.
Similarly, the change to "builtin/{fast-import,show-branch,tag}.c"
isn't needed as far as the compiler is concerned, but since they all
use the "DATE_MODE()" macro we now define in date.h, let's have them
include it.
We could simply include this new header in "cache.h", but as this
change shows these functions weren't common enough to warrant
including in it in the first place. By moving them out of cache.h
changes to this API will no longer cause a (mostly) full re-build of
the project when "make" is run.

Extend the grep tests to assert that setting
"grep.patternType=extended" followed by "grep.patternType=default"
will behave as if "--basic-regexp" was provided, and not as
"--extended-regexp". In a subsequent commit we'll need to treat
"grep.patternType=default" as a special-case, but let's make sure we
ignore it if it's being set to "default" following an earlier
non-"default" "grep.patternType" setting.
Let's also test what happens when we have a sequence of "extended"
followed by "default" and "fixed". In that case the "fixed" should
prevail, as well as tests to check that a "grep.extendedRegexp=true"
followed by a "grep.extendedRegexp=false" behaves as though
"grep.extendedRegexp" wasn't provided.
See [1] for the source of some of these tests, and their
initial (pseudocode) implementation, and [2] for a later discussion
about a breakage due to missing testing (which had been noted in [1]
all along).
