Detailed Description

One byte-addressed backing store the sweep reads through – the backend DIP seam the #208 hardware leg will implement.

setup prepares a backing for one (blob, block size) pair and publishes read/read_ctx (an ra8_vsource_read_fn, so the backing plugs straight into ra8_vsource_add_paged); teardown releases whatever setup acquired. backing_bytes reports the on-medium size of the backing (the container size for a chunked backend), and src_bytes, when non-NULL, points at a counter of raw medium bytes transferred (compressed stream bytes for the RBKC backend) so the report can separate bytes-on-the-wire from bytes-delivered-to-the-cache.

Invariant

After a successful setup, read is non-NULL until teardown.

setup/teardown calls alternate (no nested setups).
