Merge branch 'ps/refs-onbranch-fixes'

Reference backend configuration has been updated to load lazily to avoid recursive calls during repository initialization when 'onbranch' configuration conditions are evaluated. This has also fixed a memory leak and allowed the unused `chdir_notify_reparent()` machinery to be dropped. * ps/refs-onbranch-fixes: refs: protect against chicken-and-egg recursion refs/reftable: lazy-load configuration to fix chicken-and-egg reftable: split up write options refs/files: lazy-load configuration to fix chicken-and-egg refs: move parsing of "core.logAllRefUpdates" back into ref stores repository: free main reference database chdir-notify: drop unused `chdir_notify_reparent()` refs: unregister reference stores from "chdir_notify" setup: don't apply "GIT_REFERENCE_BACKEND" without a repository setup: stop applying repository format twice setup: inline `check_and_apply_repository_format()`
