[pbs-devel] [PATCH proxmox-backup v2 0/8] followups for garbage collection

[Christian Ebner <c.ebner@proxmox.com>]

This patch series contains some followup to the recently introduced
changes to phase 2 of garbage collection on s3 backed datastores [0]
and clenups for marker files during phase 3 [1], as well as some
refactoring of the chunk filename extension parsing and bad chunk
filename generation.

The first patch introduces a dedicated struct for tracking objects
to be deleted from the s3 object store during phase 2, bundling the
length and age based deletion threshold logic to the list state.

Subsequent patches rename and adapt the chunk store iterator to
optimize for regular chunk filenames and clearly distinguish chunks
by directory entry filename extension.

Further, chunk extension parsing and bad chunk filename generation are
moved to be associated functions of the newly introduced `ChunkExt`
enum.

Changes since version 1 (thanks @Fabian for comments):
- Rebased onto current master
- Followup patches for refactoring extension parsing and bad chunk
  filename generation.
