Well, it's not totally removed, some code in Item, Archive and borg transfer --from-borg1 needs to stay in place, so that we can pick the CORRECT chunks list that is in .chunks_healthy for all-zero-replacement-chunk-patched items when transferring archives from borg1 to borg2 repos. transfer: do not transfer replacement chunks, deal with missing chunks in other_repo FUSE fs read: IOError or all-zero result
it now takes either: - a list of ChunkListEntry namedtuples - a list of chunk IDs [bytes]

preloading: always use raise_missing=False, because the behaviour is defined at preloading time. fetch_many: use get_many with raise_missing=False. if get_many yields None instead of the expected chunk cdata bytes, on-the-fly create an all-zero replacement chunk of the correct size (if the size is known) and emit an error msg about the missing chunk id / size. note: for borg recreate with re-chunking this is a bit unpretty, because it will transform a missing chunk into a zero bytes range in the target file in the recreated archive. it will emit an error message at recreate time, but afterwards the recreated archive will not "know" about the problem any more and will just have that zero-patched file. so guess borg recreate with re-chunking should better only be used on repos that do not miss chunks.

extract, diff, ...: fetch_many() will on-the-fly create all-zero replacement chunks (of correct size, if size is known) if it gets a None result (not: bytes chunk cdata) from repo.get() because a chunk is missing. it will also emit an ERROR about the missing chunk, with chunk id and size.
