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
