bup already splits files and does rolling deltas, so there is no reason to
use chunking here.
The new API made it easier to add progress support for storeKey, so that's
done. Unfortunately, bup-split still outputs its own progress with -q,
so a little ugly, but not too bad.
Made dropping remove the branch for an object, for two reasons:
1. The new API calls removeKey to roll back a storeKey when the content
changed unexpectedly.
2. So that testremote will be happy.
Also, fixed a bug that caused a crash when removing the branch for an
object in rollback.
Chunking would complicate the assistant's code that checks when a pending
retrieval of a key from glacier is done. It would perhaps be nice to
support it to allow resuming, but not right now.
Converting to the new API still simplifies the code.
The forall a. in Preparer made resourcePrepare not seem to be usable, so
I specialized a to Bool. Which works for both Preparer Storer and
Preparer Retriever, but wouldn't let the Preparer be used for hasKey
as it currently stands.
And fixed a bug found by these tests; retrieveKeyFile would fail
when the dest file was already complete.

This only performs some basic tests so far; no testing of chunking or
resuming. Also, the existing encryption type of the remote is used; it
would be good later to derive an encrypted and a non-encrypted version of
the remote and test them both.

For example, I had a copy to a remote that was failing for an unknown
reason. This let me see the exception was createDirectory: permission
denied; the underlying problem being a permissions issue.
