[pbs-devel] [PATCH v5 proxmox-backup 2/4] pxar: bin: use dedicated api type for restore pattern

[Christian Ebner]

Instead of taking a plain string as input parameter, use the
corresponding api type performing additional input validation.

changes since version 4:
- pass path patterns via param and decode using `as_array`
