Client side support for SUCCESS-PLUS and ALREADY-HAVE-PLUS
is complete, when a PUT stores to additional repositories
than the expected on, the location log is updated with the
additional UUIDs that contain the content.
Started implementing PUT fanout to multiple remotes for clusters.
It is untested, and I fear fencepost errors in the relative
offset calculations. And it is missing proxying for the protocol
after DATA.
CONNECT is not supported by git-annex-shell p2pstdio, but for proxying
to tor-annex remotes, it will be supported, and will make a git pull/push
to a proxied remote work the same with that as it does over ssh,
eg it accesses the proxy's git repo not the proxied remote's git repo.
The p2p protocol docs say that NOTIFYCHANGES is not always supported,
and it looked annoying to implement it for this, and it also seems
pretty useless, so make it be a protocol error. git-annex remotedaemon
will already be getting change notifications from the proxy's git repo,
so there's no need to get additional redundant change notifications for
proxied remotes that would be for changes to the same git repo.
Added to git-annex_proxies todo because this is something OpenNeuro
would need in order to use the git-annex proxy.

importfeed: Use caching database to avoid needing to list urls on every
run, and avoid using too much memory.
Benchmarking in my podcasts repo, importfeed got 1.42 seconds faster,
and memory use dropped from 203000k to 59408k.
Database.ImportFeed is Database.ContentIdentifier with the serial number
filed off. There is a bit of code duplication I would like to avoid,
particularly recordAnnexBranchTree, and getAnnexBranchTree. But these use
the persistent sqlite tables, so despite the code being the same, they
cannot be factored out.
Since this database includes the contentidentifier metadata, it will be
slightly redundant if a sqlite database is ever added for metadata. I
did consider making such a generic database and using it for this. But,
that would then need importfeed to update both the url database and the
metadata database, which is twice as much work diffing the git-annex
branch trees. Or would entagle updating two databases in a complex way.
So instead it seems better to optimise the database that
importfeed needs, and if the metadata database is used by another command,
use a little more disk space and do a little bit of redundant work to
update it.
