[PATCH 0/3] update delete_ref(), update_ref() and ref_exists() to take a struct repository

The code handling pseudo refs such as BISECT_HEAD or CHERRY_PICK_HEAD assumes that they are files and uses unlink() and file_exists() on the corresponding paths rather than using the ref api. In repositories using reftable to store references this will not work. This patch series is a preparatory step that updates some reference functions to take a struct repository in preparation for converting code that handles pseudo refs to the ref api. The conversion will be handled by a separate series

These patches could each be split in two (thereby making the individual patches smaller) by changing the callers to pass the_repository first and then changing the call chain to pass a struct repository around if desired.

This series is based on master - 101b3204f3 ("The third batch", 2020-06-17). When merging into pu there are non-trivial conflicts with jx/proc-receive-hook, dr/push-remoteref-fix and mr/bisect-in-c-2. I have prepared a conflict resolution [1] I'm happy to rebase on top of a merge of master and those three branches if that is helpful.
