[PATCH 00/23] Memory leak fixes (pt.7)

Hi,

as usual, whenever the previous part of memory leak fixes has landed, here's the next one. This series brings us down to 80 leaking test suites. The 8th part is almost ready, too, bringing us down to 48 leaking suites. So the end is near, and I hope that our test suites are leak free after the 10th part has landed.

The patch series is built on top of ed155187b4 (Sync with Git 2.46.1, 2024-09-13) with ps/leakfixes-part-6 at 46f6ca2a68 (builtin/repack: fix leaking keep-pack list, 2024-09-05) merged into it.

Thanks!

Patrick
