A lil bit in the weeds on the chunking rewrite right now. I did succeed in
writing the core chunk generation code, which can be used for every special
remote. It was pretty hairy (needs to stream large files in constant
memory, separating into chunks, and get the progress display right
across operations on chunks, etc). That took most of the day.
Ended up getting stuck in integrating the encryptable remote code, and had
to revert changes that could have led to rewriting (or perhaps
eliminating?) most of the per-remote encryption specific code.
Up till now, this has supported both encrypted and non-encrypted remotes;
it was simply passed encrypted keys for an encrypted remote:
[[!format haskell """
remove :: Key -> Annex Bool
"""]]
But with chunked encrypted keys, it seems it needs to be more complicated:
[[!format haskell """
remove' :: Maybe (Key -> Key) -> ChunkConfig -> Key -> Annex Bool
"""]]
So that when the remote is configured to use chunking, it can look up
the chunk keys, and then encrypt them, in order to remove all the encrypted
chunk keys.
I don't like that complication, so want to find a cleaner
abstraction. Will sleep on it.

While I was looking at the encryptable remote generator, I realized
the remote cost was being calculated wrongly for special
remotes that are not encrypted. Fixed that bug.
