protocol=https implies port=443 and
port=443 implies protocol=https
-- this was necessary because the existing configs set port=443, but
with a protocol setting, users will naturally want to use it, and then
there's no need for them to supply the default https port. So we keep
back-compat, add a nicer way to enable https, and also add support for
non-standard https ports.
Makes git annex whereis display the versionId urls.
And, when a s3 remote is enabled without creds, git-annex will use the
versionId urls to access its contents.

5f0f063a7a documented it as being
configured automatically, but the code never did that. Rather than try
to hard-code whatever urls amazon uses for its buckets, it seems better
to ask the user to find the url and set it.
Security fix! Allowing any schemes, particularly file: and
possibly others like scp: allowed file exfiltration by anyone who had
write access to the git repository, since they could add an annexed file
using such an url, or using an url that redirected to such an url,
and wait for the victim to get it into their repository and send them a copy.
* Added annex.security.allowed-url-schemes setting, which defaults
to only allowing http and https URLs. Note especially that file:/
is no longer enabled by default.
* Removed annex.web-download-command, since its interface does not allow
supporting annex.security.allowed-url-schemes across redirects.
If you used this setting, you may want to instead use annex.web-options
to pass options to curl.
With annex.web-download-command removed, nearly all url accesses in
git-annex are made via Utility.Url via http-client or curl. http-client
only supports http and https, so no problem there.
(Disabling one and not the other is not implemented.)
Used curl --proto to limit the allowed url schemes.
Note that this will cause git annex fsck --from web to mark files using
a disallowed url scheme as not being present in the web. That seems
acceptable; fsck --from web also does that when a web server is not available.
youtube-dl already disabled file: itself (probably for similar
reasons). The scheme check was also added to youtube-dl urls for
completeness, although that check won't catch any redirects it might
follow. But youtube-dl goes off and does its own thing with other
protocols anyway, so that's fine.
Special remotes that support other domain-specific url schemes are not
affected by this change. In the bittorrent remote, aria2c can still
download magnet: links. The download of the .torrent file is
otherwise now limited by annex.security.allowed-url-schemes.
This does not address any external special remotes that might download
an url themselves. Current thinking is all external special remotes will
need to be audited for this problem, although many of them will use
http libraries that only support http and not curl's menagarie.
The related problem of accessing private localhost and LAN urls is not
addressed by this commit.

External special remotes can now add info to `git annex info $remote`, by
replying to the GETINFO message.
Had to generalize some helpers to allow consuming multiple messages from
the remote.
The code added to Remote/* here is AGPL licensed, thus changed the license
of the files.

git annex testremote passes.
exportree not implemented yet, although the documentation talks about it,
since it will be the main way this remote will be used.
The adb push/pull progress is displayed for now; it would be better
to consume it and use it to update the git-annex progress bar.

Renaming is not supported; it might be possible to use --fuzzy to get rsync
to notice the file is being renamed, but that is a bit ..fuzzy.
On the other hand, interrupted transfers of an exported file are resumed,
since rsync is great at that. Had to adjust the exporttree docs, which
said interrupted transfers would restart.
Note that remove no longer makes the empty directory dummy, instead
sending the top-level empty directory. This works just as well and I
noticed the dummy was unncessary when refactoring it into removeGeneric.
Verified that behavior of remove is not changed, and git annex
testremote does pass.

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.

This basically works, but there's a bug when renaming a file that leaves
a .git-annex-temp-content-key file in the webdav store, that never gets
cleaned up.
Also, exporting files with spaces to box.com seems to fail; perhaps it
does not support it?

It opens a http connection per file exported, but then so does git
annex copy --to s3.
Decided not to munge exported filenames for IA. Too large a chance of
the munging having confusing results. Instead, export of files not
supported by IA, eg with spaces in their name, will fail.

* 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.
