Caused by dirContains ".." "foo" being incorrectly False.
Also added a test of dirContains, which includes all the previous bug fixes
I could find and some obvious cases.

Fix bug that caused stale git-annex branch information to read when
annex.private or remote.name.annex-private is set.
The private journal file should not prevent reading more current
information from the git-annex branch, but used to.
Note that, overBranchFileContents has to do additional work now, when
there's a private journal file, it reads from the branch redundantly
and more slowly.

This removes a messy caveat that was easy to forget and caused at least one
bug. The price paid is that, after a write to a MultiWriter db, it has to
close the db connection that it had been using to read, and open a new
connection. So it might be a little bit slower. But, writes are usually
batched together, so there's often only a single write, and so there should
not be much of a slowdown. Notice that SingleWriter already closed the db
connection after a write, so paid the same overhead.
This is the second try at fixing a bug: git-annex get when run as the first
git-annex command in a new repo did not populate all unlocked files.

Rather than the error that occurred when trying to download the unchunked
content, which is less likely to actually be stored in the remote.

test: Put gpg temp home directory in system temp directory, not filesystem
being tested.
Since I've found indications gpg can fail talking to the agent when the
socket ends up on eg, fat. And to hopefully fix this bug report I've
followed up on.
The main risk in using the system temp dir is that TMPDIR could be set to a
long directory path, which is too long to put a unix socket in. To
partially amelorate that risk, it uses either an absolute or a relative
path, whichever is shorter. (Hopefully gpg will not convert it to a longer
form of the path..)
If the user sets TMPDIR to something so long a path to it +
"S.gpg-agent" is too long, I suppose that's their issue to deal with.

This improves the borg special remote memory usage, by
letting it only load one archive's worth of filenames into memory at a
time, and building up a larger tree out of the chunks.
When a borg repository has many archives, git-annex could easily OOM
before. Now, it will use only memory proportional to the number of
annexed keys in an archive.
Minor implementation wart: Each new chunk re-opens the content
identifier database, and also a new vector clock is used for each chunk.
This is a minor innefficiency only; the use of continuations makes
it hard to avoid, although putting the database handle into a Reader
monad would be one way to fix it.
It may later be possible to extend the ImportableContentsChunkable
interface to remotes that are not third-party populated. However, that
would perhaps need an interface that does not use continuations.
The ImportableContentsChunkable interface currently does not allow
populating the top of the tree with anything other than subtrees. It
would be easy to extend it to allow putting files in that tree, but borg
doesn't need that so I left it out for now.

This adds the overhead of a copy when serializing and deserializing keys.
I have not benchmarked much, but runtimes seem barely changed at all by that.
When a lot of keys are in memory, it improves memory use.
And, it prevents keys sometimes getting PINNED in memory and failing to GC,
which is a problem ByteString has sometimes. In particular, git-annex sync
from a borg special remote had that problem and this improved its memory
use by a large amount.
