giveup changed to filter out control characters. (It is too low level to
make it use StringContainingQuotedPath.)
error still does not, but it should only be used for internal errors,
where the message is not attacker-controlled.
Changed a lot of existing error to giveup when it is not strictly an
internal error.
Of course, other exceptions can still be thrown, either by code in
git-annex, or a library, that include some attacker-controlled value.
This does not guard against those.

Note that when this is specified and an older git-annex is used to
enableremote such a special remote, it will simply ignore the cost= field
and use whatever the default cost is.
In passing, fixed adb to support the remote.name.cost and
remote.name.cost-command configs.

None of the special remotes do it yet, but this lays the groundwork.
Added MustFinishIncompleteVerify so that, when an incremental verify is
started but not complete, it can be forced to finish it. Otherwise, it
would have skipped doing it when verification is disabled, but
verification must always be done when retrievin from export remotes
since files can be modified during retrieval.
Note that retrieveExportWithContentIdentifier doesn't support incremental
verification yet. And I'm not sure if it can -- it doesn't know the Key
before it downloads the content. It seems a new API call would need to
be split out of that, which is provided with the key.

And that should be all the special remotes supporting it on linux now,
except for in the odd edge case here and there.

Except when configuration makes curl be used. It did not seem worth
trying to tail the file when curl is downloading.
But when an interrupted download is resumed, it does not read the whole
existing file to hash it. Same reason discussed in
commit 7eb3742e4b76d1d7a487c2c53bf25cda4ee5df43; that could take a long
time with no progress being displayed. And also there's an open http
request, which needs to be consumed; taking a long time to hash the file
might cause it to time out.
Also in passing implemented it for git and external special remotes when
downloading from the web. Several others like S3 are within striking
distance now as well.

This fixes the recent reversion that annex.verify is not honored,
because retrieveChunks was passed RemoteVerify baser, but baser
did not have export/import set up.

This fixes fsck of a remote that uses chunking displaying
(checking remotename) (checking remotename)" for every chunk.
Also, some remotes displayed the message, and others did not, with no
consistency. It was originally displayed only when accessing remotes
that were expensive or might involve a password prompt, I think, but
nothing in the API said when to do it so it became an inconsistent mess.
Originally I thought fsck should always display it. But it only displays
in fsck --from remote, so the user knows the remote is being accessed,
so there is no reason to tell them it's accessing it over and over.
It was also possible for git-annex move to sometimes display it twice,
due to checking if content is present twice. But, the user of move
specifies --from/--to, so it does not need to display when it's
accessing the remote, as the user expects it to access the remote.
git-annex get might display it, but only if the remote also supports
hasKeyCheap, which is really only local git remotes, which didn't
display it always; and in any case nothing displayed it before hasKeyCheap,
which is checked first, so I don't think this needs to display it ever.
mirror is like move. And that's all the main places it would have been
displayed.

This is to support, eg a borg repo as a special remote, which is
populated not by running git-annex commands, but by using borg. Then
git-annex sync lists the content of the remote, learns which files are
annex objects, and treats those as present in the remote.
So, most of the import machinery is reused, to a new purpose. While
normally importtree maintains a remote tracking branch, this does not,
because the files stored in the remote are annex object files, not
user-visible filenames. But, internally, a git tree is still generated,
of the files on the remote that are annex objects. This tree is used
by retrieveExportWithContentIdentifier, etc. As with other import/export
remotes, that the tree is recorded in the export log, and gets grafted
into the git-annex branch.
importKey changed to be able to return Nothing, to indicate when an
ImportLocation is not an annex object and so should be skipped from
being included in the tree.
It did not seem to make sense to have git-annex import do this, since
from the user's perspective, it's not like other imports. So only
git-annex sync does it.
Note that, git-annex sync does not yet download objects from such
remotes that are preferred content. importKeys is run with
content downloading disabled, to avoid getting the content of all
objects. Perhaps what's needed is for seekSyncContent to be run with these
remotes, but I don't know if it will just work (in particular, it needs
to avoid trying to transfer objects to them), so I skipped that for now.
(Untested and unused as of yet.)

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.
