[PATCH v3 0/7] reftable: stop using Git subsystems

Hi,

this is the third version of my patch series that continues to detangle the reftable library from the Git codebase.

There is only a single change compared to v2, which is a clarification that `tmpfile_rename()` also deactivates the underlying tmpfile.

Thanks!

Patrick

Patrick Steinhardt (7):
  reftable/system: move "dir.h" to its only user
  reftable: explicitly handle hash format IDs
  reftable/system: stop depending on "hash.h"
  reftable/stack: stop using `fsync_component()` directly
  reftable/system: provide thin wrapper for tempfile subsystem
  reftable/stack: drop only use of `get_locked_file_path()`
  reftable/system: provide thin wrapper for lockfile subsystem
