e5e37517dd tests: mark tests as passing with SANITIZE=leak
This marks tests that have been leak-free since various recent
commits, but which were not marked us such when the memory leak was
fixed. These were mostly discovered with the "check" mode added in
faececa53f (test-lib: have the "check" mode for SANITIZE=leak
consider leak logs, 2022-07-28).

Commits that fixed the last memory leak in these tests. Per narrowing
down when they started to pass under SANITIZE=leak with "bisect":

- t1022-read-tree-partial-clone.sh:
  7e2619d8ff (list_objects_filter_options: plug leak of filter_spec
  strings, 2022-09-08)

- t4053-diff-no-index.sh: 07a6f94a6d (diff-no-index: release prefixed
  filenames, 2022-09-07)

- t6415-merge-dir-to-symlink.sh: bac92b1f39 (Merge branch
  'js/ort-clean-up-after-failed-merge', 2022-08-08).

- t5554-noop-fetch-negotiator.sh:
  66eede4a37 (prepare_repo_settings(): plug leak of config values,
  2022-09-08)

- t2012-checkout-last.sh, t7504-commit-msg-hook.sh,
  t91{15,46,60}-git-svn-*.sh: The in-flight "pw/rebase-no-reflog-action"
  series, upon which this is based:
  https://lore.kernel.org/git/pull.1405.git.1667575142.gitgitgadget@gmail.com/

Let's mark all of these as passing with
"TEST_PASSES_SANITIZE_LEAK=true", to have it regression tested,
including as part of the "linux-leaks" CI job.

Additionally, let's remove the "!SANITIZE_LEAK" prerequisite from
tests that now pass, these were marked as failing in:

- 77e56d55ba (diff.c: fix a double-free regression in a18d66cefb,
  2022-03-17)
- c4d1d52631 (tests: change some 'test $(git) = "x"' to test_cmp,
  2022-03-07)

These were not spotted with the new "check" mode, but manually, it
doesn't cover these sort of prerequisites. There's few enough that we
shouldn't bother to automate it. They'll be going away sooner than
later.

7a98d9ab00 revisions API: have release_revisions() release "cmdline"
Extend the the release_revisions() function so that it frees the
"cmdline" in the "struct rev_info". This in combination with a
preceding change to free "commits" and "mailmap" means that we can
whitelist another test under "TEST_PASSES_SANITIZE_LEAK=true".

There was a proposal in [1] to do away with xstrdup()-ing this
add_rev_cmdline(), perhaps that would be worthwhile, but for now let's
just free() it.

We could also make that a "char *" in "struct rev_cmdline_entry"
itself, but since we own it let's expose it as a constant to outside
callers. I proposed that in [2] but have since changed my mind. See
14d30cdfc0 (ref-filter: fix memory leak in `free_array_item()`,
2019-07-10), c514c62a4f (checkout: fix leak of non-existent branch
names, 2020-08-14) and other log history hits for "free((char *)" for
prior art.

This includes the tests we had false-positive passes on before my
6798b08e84 (perl Git.pm: don't ignore signalled failure in
_cmd_close(), 2022-02-01), now they pass for real.

Since there are 66 tests matching t/t[0-9]*git-svn*.sh it's easier to
list those that don't pass than to touch most of those 66. So let's
introduce a "TEST_FAILS_SANITIZE_LEAK=true", which if set in the tests
won't cause lib-git-svn.sh to set "TEST_PASSES_SANITIZE_LEAK=true.

This change also marks all the tests that we removed
"TEST_FAILS_SANITIZE_LEAK=true" from in an earlier commit due to
removing the UNLEAK() from cmd_format_patch(), we can now assert that
its API use doesn't leak any "struct rev_info" memory.

This change also made commit "t5503-tagfollow.sh" pass on current
master, but that would regress when combined with
ps/fetch-atomic-fixup's de004e848a (t5503: simplify setup of test
which exercises failure of backfill, 2022-03-03) (through no fault of
that topic, that change started using "git clone" in the test, which
has an outstanding leak). Let's leave that test out for now to avoid
in-flight semantic conflicts.

0c51d6b4ae t6000-t9999: detect and signal failure within loop
Failures within `for` and `while` loops can go unnoticed if not detected
and signaled manually since the loop itself does not abort when a
contained command fails, nor will a failure necessarily be detected when
the loop finishes since the loop returns the exit code of the last
command it ran on the final iteration, which may not be the command
which failed. Therefore, detect and signal failures manually within
loops using the idiom `|| return 1` (or `|| exit 1` within subshells).

55f9d7a75c git-svn: add an option to skip the creation of empty directories
"git svn mkdirs" (which creates empty directories in the current
working copy) can be very slow and is often unnecessary.  Provide a
config file option "svn-remote.<name>.automkdirs" that prevents empty
directories from being created automatically.  (They are still created
if "git svn mkdirs" is invoked explicitly.)

2dec68cf8f tests: add missing &&, batch 2
Same rules as before: this patch only adds " &&" to the end of
some lines in the test suite.

Intended to be applied on top of or squashed with the last
batch if they look okay.

a5b80d9263 git svn: make empty directory creation gc-aware
The "git svn gc" command creates and appends to unhandled.log.gz
files which should be parsed before the uncompressed
unhandled.log files.

f9ad77a739 git svn: log removals of empty directories
This also adds a test case for:
  "git svn: Don't create empty directories whose parents were deleted"
which was the reason we found this bug in the first place.

9be30eed61 git svn: strip leading path when making empty dirs
Since unhandled.log stores paths relative to the repository
root, we need to strip out leading path components if the
directories we're tracking are not the repository root.

6111b93499 git svn: attempt to create empty dirs on clone+rebase
We parse unhandled.log files for empty_dir statements and make a
best effort attempt to recreate empty directories on fresh
clones and rebase.  This should cover the majority of cases
where users work off a single branch or for projects where
branches do not differ in empty directories.

Since this cannot affect "normal" git commands like "checkout"
or "reset", so users switching between branches in a single
working directory should use the new "git svn mkdirs" command
after switching branches.
