[PATCH v1 proxmox-backup 0/3] improve handling of bad S3 chunks during GC

[Robert Obkircher <r.obkircher@proxmox.com>]

Fix an issue where the local path of .i.bad files was computed
incorrectly, and refactor the related code a bit.

I discovered this issue while grepping for "unsafe" to see if it would
make sense to (explicitly) depend on the zerocopy crate for the index
file readers. The removed unsafe statement in the first patch looked
suspicious because it could have been out-of-bounds if to_string_lossy
wasn't guaranteed to be called on an utf8 OsStr.

Robert Obkircher (3):
  datastore: fix local path for .i.bad chunk files during S3 GC
  datastore: check that .i.bad files from S3 actually match that pattern
  datastore: introduce helper function to parse digest from S3ObjectKey
