This patchset fixes a couple of minor memory leaks I found by running
"make check" for the arm targets with the clang leak sanitizer enabled.
Version 2 also includes some patches by Fabiano from last year that
fell through the cracks; I've rebased them and included them here.

Changes in v2:
 * patch 1 now just moves the file to keep 'git log --follow' happy
 * patch 1 fixes the filename in tests/docker/test-fuzz
 * patch 2 has the SPDX/doc comment that were in patch 1 before
 * patch 2 drops the walk_path suppression as one of Fabiano's
   patches fixes this leak properly
 * patches 5-9 are from Fabiano; most were reviewed last year

Patches still needing review: just patch 1.

thanks

Since these patches have all been reviewed, I'm going to take
them into target-arm.next. Let me know if you'd prefer something
else or if anybody wants more time to review.

thanks
