update licenses from GPL to AGPL
This does not change the overall license of the git-annex program, which
was already AGPL due to a number of sources files being AGPL already.

Legally speaking, I'm adding a new license under which these files are
now available; I already released their current contents under the GPL
license. Now they're dual licensed GPL and AGPL. However, I intend
for all my future changes to these files to only be released under the
AGPL license, and I won't be tracking the dual licensing status, so I'm
simply changing the license statement to say it's AGPL.

(In some cases, others wrote parts of the code of a file and released it
under the GPL; but in all cases I have contributed a significant portion
of the code in each file and it's that code that is getting the AGPL
license; the GPL license of other contributors allows combining with
AGPL code.)

clean P2P protocol shutdown on EOF try 2
Same goal as b18fb1e343 but without
breaking backwards compatability. Just return IO exceptions when running
the P2P protocol, so that git-annex-shell can detect eof and avoid the
ugly message.

add Remote.readonly
Does nothing yet.

Considered making bup readonly, but while the content can't be removed,
it is able to delete a branch, so didn't.

add retrievalSecurityPolicy
This will be used to protect against CVE-2018-10859, where an encrypted
special remote is fed the wrong encrypted data, and so tricked into
decrypting something that the user encrypted with their gpg key and did
not store in git-annex.

It also protects against CVE-2018-10857, where a remote follows a http
redirect to a file:// url or to a local private web server. While that's
already been prevented in git-annex's own use of http, external special
remotes, hooks, etc use other http implementations and could still be
vulnerable.

The policy is not yet enforced, this commit only adds the appropriate
metadata to remotes.

removal of the rest of remoteGitConfig
In keyUrls, the GitConfig is used only by annexLocations
to support configured Differences. Since such configurations affect all
clones of a repository, the local repo's GitConfig must have the same
information as the remote's GitConfig would have. So, used getGitConfig
to get the local GitConfig, which is cached and so available cheaply.

That actually fixed a bug noone had ever noticed: keyUrls is
used for remotes accessed over http. The full git config of such a
remote is normally not available, so the remoteGitConfig that keyUrls
used would not have the necessary information in it.

In copyFromRemoteCheap', it uses gitAnnexLocation,
which does need the GitConfig of the remote repo itself in order to
check if it's crippled, supports symlinks, etc. So, made the
State include that GitConfig, cached. The use of gitAnnexLocation is
within a (not $ Git.repoIsUrl repo) guard, so it's local, and so
its git config will always be read and available.

(Note that gitAnnexLocation in turn calls annexLocations, so the
Differences config it uses in this case comes from the remote repo's
GitConfig and not from the local repo's GitConfig. As explained above
this is ok since they must have the same value.)

Not very happy with this mess of different GitConfigs not type-safe and
some read only sometimes etc. Very hairy. Think I got it this change
right. Test suite passes..

change Remote.repo to Remote.getRepo
This is groundwork for letting a repo be instantiated the first time
it's actually used, instead of at startup.

The only behavior change is that some old special cases for xmpp remotes
were removed. Where before git-annex silently did nothing with those
no-longer supported remotes, it may now fail in some way.

The additional IO action should have no performance impact as long as
it's simply return.

fix nested progress meters when using git-annex-shell fallback

but also it may have confused -J display.

version the P2P protocol
Unfortunately ReceiveMessage didn't handle unknown messages the way it
was documented to; client sending VERSION would cause the server to
return an ERROR and hang up. Fixed that, but old releases of git-annex
use the P2P protocol for tor and will still have that behavior.

So, version is not negotiated for Remote.P2P connections, only for
Remote.Git connections, which will support VERSION from their first
release. There will need to be a later flag day to change Remote.P2P;
left a commented out line that is the only thing that will need to be
changed then.

Version 1 of the P2P protocol is not implemented yet, but updated
the docs for the DATA change that will be allowed by that version.

refactor p2p remote action code
Make a Remote.Helper.P2P using code that was in Remote.P2P, converted to
use generic protocol runner actions.

This will allow it to be reused in Remote.Git.

p2p ssh connection pools
Much like Remote.P2P, there's a pool of connections to a peer, in order
to support concurrent operations.

Deals with old git-annex-ssh on the remote that does not support p2pstdio,
by only trying once to use it, and remembering if it's not supported.

Made p2pstdio send an AUTH_SUCCESS with its uuid, which serves the dual
purposes of something to detect to see that the connection is working,
and a way to verify that it's connected to the right uuid.
(There's a redundant uuid check since the uuid field is sent
by git_annex_shell, but I anticipate that being removed later when
the legacy git-annex-shell stuff gets removed.)

Not entirely happy with Remote.Git.runSsh's behavior
when the proto action fails. Running the fallback will work ok, but what
will we do when the fallbacks later get removed? It might be better to
try to reconnect, in case the connection got closed.

prevent exporttree=yes on remotes that don't support exports
Don't allow "exporttree=yes" to be set when the special remote
does not support exports. That would be confusing since the user would
set up a special remote for exports, but `git annex export` to it would
later fail.

allow them. Also, exportSupported will be useful for the external

add API for exporting
Implemented so far for the directory special remote.

Several remotes don't make sense to export to. Regular Git remotes,
obviously, do not. Bup remotes almost certianly do not, since bup would
need to be used to extract the export; same store for Ddar. Web and
Bittorrent are download-only. GCrypt is always encrypted so exporting to
it would be pointless. There's probably no point complicating the Hook
remotes with exporting at this point. External, S3, Glacier, WebDAV,
Rsync, and possibly Tahoe should be modified to support export.

Thought about trying to reuse the storeKey/retrieveKeyFile/removeKey
interface, rather than adding a new interface. But, it seemed better to
keep it separate, to avoid a complicated interface that sometimes
encrypts/chunks key/value storage and sometimes users non-key/value
storage. Any common parts can be factored out.

Note that storeExport is not atomic.
doc/design/exporting_trees_to_special_remotes.mdwn has some things in
the "resuming exports" section that bear on this decision. Basically,
I don't think, at this time, that an atomic storeExport would help with
resuming, because exports are not key/value storage, and we can't be
sure that a partially uploaded file is the same content we're currently
trying to export.

Also, note that ExportLocation will always use unix path separators.
This is important, because users may export from a mix of windows and
unix, and it avoids complicating the API with path conversions,
and ensures that in such a mix, they always use the same locations for
exports.

stub Remote.P2P
Similar to GCrypt remotes, P2P remotes have an url, so Remote.Git has to
separate them out and handle them, passing off to Remote.P2P.
