Git - v2.36.2

This release merges up the fixes that appear in v2.30.5, v2.31.4,
v2.32.3, v2.33.4, v2.34.4 and v2.35.4 to address the security
issue CVE-2022-29187; see the release notes for these versions
for details.

Apart from that, this maintenance release is primarily to merge down
updates to the build and CI procedures from the 'master' front, in
order to ensure that we can cut healthy maintenance releases in the
future. It also contains a handful of small and trivially-correct
bugfixes.

Fixes since v2.36.1

• Fixes real problems noticed by gcc 12 and works around false
  positives.

• Update URL to the gitk repository.

• The "--current" option of "git show-branch" should have been made
  incompatible with the "--reflog" mode, but this was not enforced,
  which has been corrected.

• "git archive --add-file=" picked up the raw permission bits
  from the path and propagated to zip output in some cases, without
  normalization, which has been corrected (tar output did not have
  this issue).

• A bit of test framework fixes with a few fixes to issues found by
  valgrind.

• macOS CI jobs have been occasionally flaky due to tentative version
  skew between perforce and the homebrew packager. Instead of
  failing the whole CI job, just let it skip the p4 tests when this
  happens.

• The commit summary shown after making a commit is matched to what
  is given in "git status" not to use the break-rewrite heuristics.

• Avoid problems from interaction between malloc_check and address
  sanitizer.

• "git rebase --keep-base " computed the
  commit to rebase onto incorrectly, which has been corrected.

• The path taken by "git multi-pack-index" command from the end user
  was compared with path internally prepared by the tool withut first
  normalizing, which lead to duplicated paths not being noticed,
  which has been corrected.

• "git clone --origin X" leaked piece of memory that held value read
  from the clone.defaultRemoteName configuration variable, which has
  been plugged.
