[pbs-devel] [PATCH v9 proxmox-backup 06/58] client: tools: helper to check pxar filename extensions

[Christian Ebner]

With the introduction of split pxar archives, the allowed extensions
are now `.pxar`, `.mpxar` and `.ppxar`. Add a helper function to
allow to check for all valid variants, including the optional
additional `.didx` in case of a server archive name.
