Merge branch 'rj/test-sanitize-leak-log-fix'

Tests that use GIT_TEST_SANITIZE_LEAK_LOG feature got their exit
status inverted, which has been corrected.

* rj/test-sanitize-leak-log-fix:
  test-lib: GIT_TEST_SANITIZE_LEAK_LOG enabled by default
  test-lib: fix GIT_TEST_SANITIZE_LEAK_LOG

-With GIT_TEST_SANITIZE_LEAK_LOG=true we'll look at the leak logs
-before exiting and exit on failure if the logs showed that we had a
-memory leak, even if the test itself would have otherwise passed. This
-allows us to catch e.g. missing &&-chaining. This is especially useful
-when combined with "GIT_TEST_PASSING_SANITIZE_LEAK", see below.
-
 GIT_TEST_PASSING_SANITIZE_LEAK=check when combined with "--immediate"
 will run to completion faster, and result in the same failing
-tests. The only practical reason to run
-GIT_TEST_PASSING_SANITIZE_LEAK=check without "--immediate" is to
-combine it with "GIT_TEST_SANITIZE_LEAK_LOG=true". If we stop at the
-first failing test case our leak logs won't show subsequent leaks we
-might have run into.

-GIT_TEST_PASSING_SANITIZE_LEAK=(true|check) will not catch all memory
-leaks unless combined with GIT_TEST_SANITIZE_LEAK_LOG=true. Some tests
-run "git" (or "test-tool" etc.) without properly checking the exit
-code, or git will invoke itself and fail to ferry the abort() exit
-code to the original caller. When the two modes are combined we'll
-look at the "test-results/$TEST_NAME.leak/trace.*" files at the end of
-the test run to see if had memory leaks which the test itself didn't
-catch.
