When autoenabling special remotes of type S3, weddav, or glacier, do not
take login credentials from environment variables, as the user may not be
expecting the autoenable to happen, and may have those set for other
purposes.
Which access a remote using rsync over ssh, and which git pushes to much
more efficiently than ssh urls.
There was some old partial support for rsync URIs from 2013, but it seemed
incomplete, and did not use rsync over ssh. Weird.
I'm not sure if there's any remaining benefit to using the non-rsync url
forms with gcrypt, now that this is implemented? Updated docs to encourage
using the rsync urls.

Note that, after changing it with enableremote, syncing won't rescan
known archives in the borg repo using the changed config. Probably not a
problem?
Also used File in some places where filenames that could theoretically
start with - are passed to borg, to avoid it confusing them with
options.
So these special remotes are always supported.
IIRC these build flags were added because the dep chains were a bit too
long, or perhaps because the libraries were not available in Debian stable,
or something like that. That was long ago, those reasons no longer apply,
and users get confused when builtin special remotes are not available, so
it seems best to remove the build flags now.
If this does cause a problem it can be reverted of course..

Also tested what happens if the other special remote has importtree=yes
and exporttree=yes, and in that case, download via httpalso works too,
without needing to implement any importtree methods here.
It might be possible to make it automatically set exporttree=yes if the
--sameas does. Didn't try, will probably be layering issues.
Or perhaps it should be inherited by sameas like some
other configs? But then, wouldn't it also make sense to inherit
importree=yes? But as shown here, it's not needed by this kind of
remote.
"http" was too generic and easy to confuse with web. The new name makes
clear it's used in addition to some other remote. And other protocols
can use the same naming scheme.
To use S3 Signature Version 4. Some S3 services seem to require v4, while
others may only support v2, which remains the default.
I'm also not sure if v4 works correctly in all cases, there is this
upstream bug report: https://github.com/aristidb/aws/issues/262
I've only tested it against the default S3 endpoint.
In several cases, there's an old, maybe unmaintained special remote,
and rclone also supports the service. I don't know which is better,
so I added tips pages for these, listing both possibilies, so users can
fill in the details.
Added some things listed in special_remotes/rclone that were not
in the cloud provider list, so users will see it supports those.
But, omitted S3 and webdav, since it's probably better for users to use
what's built into git-annex than going via rclone.
The rclone list is out of date apparently, as rclone.org has more,
so I added a note at the bottom for users to check.

Special remote programs that use GETCONFIG/SETCONFIG are recommended
to implement it.
The description is not yet used, but will be useful later when adding a way
to make initremote list all accepted configs.
configParser now takes a RemoteConfig parameter. Normally, that's not
needed, because configParser returns a parter, it does not parse it
itself. But, it's needed to look at externaltype and work out what
external remote program to run for LISTCONFIGS.
Note that, while externalUUID is changed to a Maybe UUID, checkExportSupported
used to use NoUUID. The code that now checks for Nothing used to behave
in some undefined way if the external program made requests that
triggered it.
Also, note that in externalSetup, once it generates external,
it parses the RemoteConfig strictly. That generates a
ParsedRemoteConfig, which is thrown away. The reason it's ok to throw
that away, is that, if the strict parse succeeded, the result must be
the same as the earlier, lenient parse.
initremote of an external special remote now runs the program three
times. First for LISTCONFIGS, then EXPORTSUPPORTED, and again
LISTCONFIGS+INITREMOTE. It would not be hard to eliminate at least
one of those, and it should be possible to only run the program once.
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.
