[PATCH 0/3] leak tests: mark remaining tests leak-free as such

While working on another topic that cleared up some leaks, I wanted to see if any new tests became leak-free, so I ran:

    $ make SANITIZE=leak
    $ make GIT_TEST_PASSING_SANITIZE_LEAK=check GIT_TEST_OPTS=-i test

, and was surprised to see so many tests appear in the "failed" list (indicating that they are free of leaks, but did not mark themselves as such).

In fact, the patch I had written at the time didn't make a dent one way or another in the list of leak-free tests, as the same results were produced on 'master' without my changes.

This series marks all leak-free tests as such, meaning that the above "make test" invocation will pass after this series. The bulk of the tests which are marked here in the first patch were always leak-free[^1]. The remaining two patches address a couple of special cases of tests which are also leak-free.

Thanks in advance for your review!

[^1]: At least as far back as v2.38.0, when the "check" mode of
  GIT_TEST_PASSING_SANITIZE_LEAK was first introduced.
