This turns out to only be necessary is edge cases. Most of the
time, git-annex unused --from remote doesn't see git-remote-annex keys
at all, because it does not record a location log for them.
On the other hand, git-annex unused does find them, since it does not
rely on the location log. And that's good because they're a local cache
that the user should be able to drop.
If, however, the user ran git-annex unused and then git-annex move
--unused --to remote, the keys would have a location log for that
remote. Then git-annex unused --from remote would see them, and would
consider them unused. Even when they are present on the special remote
they belong to. And that risks losing data if they drop the keys from
the special remote, but didn't expect it would delete git branches they
had pushed to it.
So, make git-annex unused --from skip git-remote-annex keys whose uuid
is the same as the remote.
I hope to support importtree=yes eventually, but it does not currently
work.
Added remote.<name>.allow-encrypted-gitrepo that needs to be set to
allow using it with encrypted git repos.
Note that even encryption=pubkey uses a cipher stored in the git repo
to encrypt the keys stored in the remote. While it would be possible to
not encrypt the GITBUNDLE and GITMANIFEST keys, and then allow using
encryption=pubkey, it doesn't currently work, and that would be a
complication that I doubt is worth it.
Updating the remote list needs the config to be written to the git-annex
branch, which was not done for good reasons. While it would be possible
to instead use Remote.List.remoteGen without writing to the branch, I
already have a plan to discard git-annex branch writes made by
git-remote-annex, so the simplest fix is to write the config to the
branch.

Put the annex objects in .git/annex/objects/ inside the export remote.
This way, when importing from the remote, they will be filtered out.
Note that, when importtree=yes, content identifiers are used, and this
means that pushing to a remote updates the git-annex branch. Urk.
Will need to try to prevent that later, but I already had a todo about
that for other reasons.
Untested!

Otherwise, it can be confusing to clone from a wrong url, since it fails
to download a manifest and so appears as if the remote exists but is empty.

This will eventually be used to recover from an interrupted fullPush
and drop the old bundle keys it was unable to delete.

Update its todo with remaining items.
Add changelog entry.
Simplified internals document to no longer be notes to myself, but
target users who want to understand how the data is stored
and might want to extract these repos manually.
