Adds a dedicated structure to hold the optional sender and receiver
instances and state for injection of reused dynamic entries in the
payload stream for split stream pxar archives.
The asynchronous channels must only be attached to the payload
archive, leaving the current behaviour for the metadata archive and
current default encoding without reusing payload chunks of previous
snapshots.
