[PATCH 0/5] pack-write: cleanup usage of global variables

This is a small series to remove global variable usage from `pack-write.c`. Mostly it bubble's up the usage of global variables to upper layers. The only exception is in `write-midx.c`, which was cleaned of global variable usage, so there, we use the repo that is in available in the context.

This series is based on fbe8d3079d (Git 2.48, 2025-01-10) with 'ps/more-sign-compare' and 'ps/the-repository' merged in.

There are no conflicts with topics in 'next', however there is a conflict with 'tb/incremental-midx-part-2' in 'seen', the fix is simple but happy to merge that in too if necessary.
