Christian Hesse a6da40bf84 git: update to v2.41.0
Update to git version v2.41.0, with lots of changes...
This requires changes for these upstream commits:

* 60ff56f50372c1498718938ef504e744fe011ffb
  banned.h: mark `strtok()` and `strtok_r()` as banned

* 52acddf36c8cb3778ab2098a0d95cc2e375a4069
  string-list: multi-delimiter `string_list_split_in_place()`

* d850b7a545fcfbd97460a921c7f7c59d933eb0f7
  cocci: apply the "cache.h" part of "the_repository.pending"

* cb338c23d6d518947bf6f7240bf30e2ec232bd3b
  cocci: apply the "commit-reach.h" part of "the_repository.pending"

* ecb5091fd4301ac647db0bd2504112b38f7ee06d
  cocci: apply the "commit.h" part of "the_repository.pending"

* 085390328f5fe1dfba67039b1fd6cc51546a4e41
  cocci: apply the "diff.h" part of "the_repository.pending"

* bc726bd075929aab6b3e09d4dd5c2b0726fd5350
  cocci: apply the "object-store.h" part of "the_repository.pending"

* bab821646a74c446370fa8d01ca851f247df5033
  cocci: apply the "pretty.h" part of "the_repository.pending"

* afe27c889429438829bc8818ed17e4960bd3ef02
  cocci: apply the "packfile.h" part of "the_repository.pending"

* 12cb1c10a64170a5d600dd1c6c8abfeec105fb6b
  cocci: apply the "refs.h" part of "the_repository.pending"

* 035c7de9e9ea11d26df5f9e4bb117f91ed11a9fd
  cocci: apply the "revision.h" part of "the_repository.pending"

... and some more I missed to list 😜 - for example the move and cleanup
of headers and includes (see changes in `cgit.h`) comes to mind...
