[PATCH 00/23] Memory leak fixes (pt.8)

Hi,

this is the 8th series of memory leak fixes. As usual, it fixes memory leaks all over the place. Once applied, we're down to 35 test suites that do not pass with the memory leak sanitizer.

This series is built on top of 3857aae53f (Git 2.47-rc0, 2024-09-25) with the following two topisc merged into it:

  - ps/leakfixes-part-7 at 12dfc2475c (diffcore-break: fix leaking
    filespecs when merging broken pairs, 2024-09-26).

  - jk/http-leakfixes at f4c768c639 (http-push: clean up local_refs at
    exit, 2024-09-24).

Both of these topics are part of `next`.

Thanks!

Patrick
