[pbs-devel] [RFC pxar 02/36] format/examples: add PXAR_PAYLOAD_REF entry header

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

Introduces a new PXAR_PAYLOAD_REF entry header to mark regular file
payloads which are not encoded within the regular pxar archive stream
but rather redirected to a different output stream.

The corresponding header marks the entry containing all the necessary
data for restoring the actual payload from the dedicated payload stream.
