[pbs-devel] [PATCH v4 proxmox-backup 41/58] client: streams: add channels for dynamic entry injection

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

To reuse dynamic entries of a previous backup run and index them for
the new snapshot. Adds a non-blocking channel between the pxar
archiver and the chunk stream, as well as the chunk stream and the
backup writer.

The archiver sends forced boundary positions and the dynamic
entries to inject into the chunk stream following this boundary.

The chunk stream consumes this channel inputs as receiver whenever a
new chunk is requested by the upload stream, forcing a non-regular
chunk boundary in the pxar stream at the requested positions.

The dynamic entries to inject and the boundary are then send via the
second asynchronous channel to the backup writer's upload stream,
indexing them by inserting the dynamic entries as known chunks into
the upload stream.
