Not yet used by git-annex, but this will allow faster transfers etc than
using individual ssh connections and rsync.
Not called git-annex-shell p2p, because git-annex p2p does something
else and I don't want two subcommands with the same name between the two
for sanity reasons.

Allows using new special remote messages when git-annex supports them,
and avoiding using them when git-annex is too old. The new INFO is one
such message.
There's also the possibility, currently unused, for the special remote's
reply to include some kind of extensions of its own.
Merging this is blocked by https://github.com/datalad/datalad/issues/2124
since it seems it will break datalad. I checked all the other special
remotes and they will be ok.

It's left up to the special remote to detect when git-annex is new enough
to support the message; an old git-annex will blow up.

Not yet called by Command.Export.
WebDAV needs this to clean up empty collections. Also, example.sh turned
out to not be cleaning up directories when removing content
from them, so it made sense for it to use this.
Remote.Directory did not need it, and since its cleanup method for empty
directories is more efficient than what Command.Export will need to do
to find empty directories, it uses Nothing so that extra work can be
avoided.

Got rid of RENAMEEXPORT-UNSUPPORTED, no reason not to use
RENAMEEXPORT-FAILURE for that.

The export database has writes made to it and then expects to read back
the same data immediately. But, the way that Database.Handle does
writes, in order to support multiple writers, makes that not work, due
to caching issues. This resulted in export re-uploading files it had
already successfully renamed into place.
Fixed by allowing databases to be opened in MultiWriter or SingleWriter
mode. The export database only needs to support a single writer; it does
not make sense for multiple exports to run at the same time to the same
special remote.
All other databases still use MultiWriter mode. And by inspection,
nothing else in git-annex seems to be relying on being able to
immediately query for changes that were just written to the database.

This is seriously super hairy. It has to handle interrupted exports,
which may be resumed with the same or a different tree. It also has to
recover from export conflicts, which could cause the wrong content
to be renamed to a file.
I think this works, or is close to working. See the update to the design
for how it works.
This is definitely not optimal, in that it does more renames than are
necessary. It would probably be worth finding the keys that are really
renamed and only renaming those. But let's get the "simple" approach to
work first..

This gets complicated, but I think this design will work!

Removed uncorrect UniqueKey key in db schema; a key can appear multiple
times with different files.
The database has to be flushed after each removal. But when adding files
to the export, lots of changes are able to be queued up w/o flushing.
So it's still fairly efficient.
If large removals of files from exports are too slow, an alternative
would be to make two passes over the diff, one pass queueing deletions
from the database, then a flush and the a second pass updating the
location log. But that would use more memory, and need to look up
exportKey twice per removed file, so I've avoided such optimisation yet.

* Only export to remotes that were initialized to support it.
* Prevent storing key/value on export remotes.
* Prevent enabling exporttree=yes and encryption in the same remote.
SetupStage Enable was changed to take the old RemoteConfig.
This allowed only setting exporttree when initially setting up a
remote, and not configuring it later after stuff might already be stored
in the remote.
Went with =yes rather than =true for consistency with other parts of
git-annex. Changed docs accordingly.

This will allow disabling exports for remotes that are not configured to
allow them. Also, exportSupported will be useful for the external
special remote to probe.

So it will be available later and elsewhere, even after GC.
I first though to use git update-index to do this, but feeding it a line
with a tree object seems to always cause it to generate a git subtree
merge. So, fell back to using the Git.Tree interface to maniupulate the
trees, and not involving the git-annex branch index file at all.

This avoids needing to deal with the complexity of partially transferred
files in the export. We'd not be able to resume uploading to such a file
anyway, so just avoid them.
The implementation in Remote.Directory is not completely ideal, because
it could leave the temp file hanging around in the export directory.
This only happens if it's killed with -9, or there's a power failure;
normally viaTmp cleans up after itself, even when interrupted. I could
not see a better way to do it though, since the export directory might
be the root of a filesystem.
Also some design thoughts on resuming, which depend on storeExport being
atomic.

Make a pass over the whole exported tree, and upload anything that has
not yet reached the export. Update location log when exporting.
Note that the synthesized keys for non-annexed files are stored in the
location log too.
Some cases involving files in the tree with the same content are not
handled correctly yet.

External special remotes will refuse to operate on keys with spaces in
their names. That has never worked correctly due to the design of the
external special remote protocol. Display an error message suggesting
migration.
Not super happy with this, but it's a pragmatic solution. Better than
complicating the external special remote interface and all external special
remotes.
Note that I only made it use SafeKey in Request, not Response. git-annex
does not construct a Response, so that would not add any safety. And
presumably, if git-annex avoids feeding any such keys to an external
special remote, it will never have a reason to make a Response using such a
key. If it did, it would result in a protocol error anyway.
There's still a Serializeable instance for Key; it's used by P2P.Protocol.
There, the Key is always in the final position, so it's ok if it contains
spaces.
Note that the protocol documentation has been fixed to say that the File
may contain spaces. One way that can happen, even though the Key can't,
is when using direct mode, and the work tree filename contains spaces.
When sending such a file to the external special remote the worktree
filename is used.
