v6: When a file is unlocked but has not been modified, and the unlocking is
only staged, git-annex add did not lock it. Now it will, for consistency
with how modified files are handled and with v5.
Note the removal of the sameInodeCache check. Otherwise it would see
that the unmodified file is unmodified and stop there. That check seems to have
been copied from the direct mode branch. But, direct mode had a specific
reason to check for unmodified content, that does not apply to v6.
The second pass means there is potential for a race, eg the unlocked
file could be modified in between the first and second passes.
No problem with that, since both passes do the same thing.

* Don't use GIT_PREFIX when GIT_WORK_TREE=. because it seems git
does not intend GIT_WORK_TREE to be relative to GIT_PREFIX in that
case, despite GIT_WORK_TREE=.. being relative to GIT_PREFIX.
* Don't use GIT_PREFIX to fix up a relative GIT_DIR, because
git 2.11 sets GIT_PREFIX set to a path it's not relative to.
and apparently GIT_DIR is never relative to GIT_PREFIX.
Commit e50ed4ba48 led us down this path
by working around a git bug by relying on the barely documented GIT_PREFIX.

v6: Fix annex object file permissions when git-annex add is run on a
modified unlocked file, and in some related cases.
If a hard link is made, don't freeze it; annex.thin
uses writable object files.
Also: For some reason, linkToAnnex used to thawContent src. I can see no
reason why it needed to do that, so I eliminated that.

Probably not noticed until now because the queue is large enough that two
threads each filling theirs at the same time and flushing is unlikely to
happen.
Also made explicit that each worker thread gets its own queue.
I think that was the case before, but if something was put in the queue
before worker threads were forked off, they could have each inherited the
same queue.
Could have gone with a single shared queue, but per-worker queues is more
efficient, because a worker can add lots of stuff to its own queue without
any locking.

Avoids annex.largefiles inconsitency and also avoids a lot of
unneccessary calls to the clean filter when a large repo's clone
is being initialized.
This commit was supported by the NSF-funded DataLad project.
v6: When annex.largefiles is not configured for a file, running git add or
git commit, or otherwise using git to stage a file will add it to the annex
if the file was in the annex before, and to git otherwise. This is to avoid
accidental conversion.
Note that git-annex add's behavior has not changed, for reasons explained
in the added comment.
Performance: No added overhead when annex.largefiles is configured.
When not configured, there is an added call to catObjectMetaData,
which involves a round trip through git cat-file --batch.
However, the earlier catKeyFile primes the cache for it.
This commit was supported by the NSF-funded DataLad project.
When --batch is used with matching options like --in, --metadata, etc, only
operate on the provided files when they match those options. Otherwise, a
blank line is output in the batch protocol.
Affected commands: find, add, whereis, drop, copy, move, get
In the case of find, the documentation for --batch already said it honored
the matching options. The docs for the rest didn't, but it makes sense to
have them honor them. While this is a behavior change, why specify the
matching options with --batch if you didn't want them to apply?
Note that the batch output for all of the affected commands could
already output a blank line in other cases, so batch users should
already be prepared to deal with it.
git-annex metadata didn't seem worth making support the matching options,
since all it does is output metadata or set metadata, the use cases for
using it in combination with the martching options seem small. Made it
refuse to run when they're combined, leaving open the possibility for later
support if a use case develops.

Added getStaged, to get the versions of git-annex branch files staged in its
index, and use during transitions so the result of merging sibling branches
is used.
The catFileStop in performTransitionsLocked is absolutely necessary,
without that the bug still occurred, because git cat-file was already
running and was looking at the old index file.
Note that getLocal still has cat-file look at the git-annex branch, not the
index. It might be faster if it looked at the index, but probably only
marginally so, and I've not benchmarked it to see if it's faster at all. I
didn't want to change unrelated behavior as part of this bug fix. And as
the need for catFileStop shows, using the index file has added
complications.
Anyway, it still seems fine for getLocal to look at the git-annex branch,
because normally the index file is updated just before the git-annex branch
is committed, and so they'll contain the same information. It's only during
a transition that the two diverge.

Work around git bug that runs smudge/clean filters at the top of the
repository while passing them a relative GIT_WORK_TREE that may point
outside of the repository, by using GIT_PREFIX to get back to the
subdirectory where a relative GIT_WORK_TREE is valid.
git devs have been informed of the bug and may fix it, which could conveivably
break this fix, but as it is, this works back to git 1.7.6.

Send User-Agent and any configured annex.http-headers when downloading with

Display error messages that come from git-annex-shell when the p2p protocol
is used, so that diskreserve messages, IO errors, etc from the remote side
are visible again.
Felt like it should perhaps use outputError, so --json-error-messages would
include these, but as an async IO action, it can't, and this would need
MessageState to be converted to a tvar. Anyway, when not using p2pstdio,
that's not done; nor is it done for stderr from external special remotes
or other commands, so punted on the idea for now.

I can't find any documentation of how long it should be. Hard to imagine
it being shorter than 4 characters though, so put that in as a conservative
lower bound.

Fixed annex-checkuuid implementation, so that remotes configured that way
can be used. This was 100% broken from the first commit of it, oops.
This commit was sponsored by Øyvind Andersen Holm.
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.

Show operating system and repository version list when run outside
a git repo too.
Also made it only display the local repository version when in a git-annex
repo. Before it showed "unknown" when run in a git repo that was not
git-annex initialized. That seemed like confusing behavior.

https://prime.haskell.org/wiki/Libraries/Proposals/SemigroupMonoid
I am not happy with the fragile pile of CPP boilerplate required to support
ghc back to 7.0, which git-annex still targets for both the android build
and the standalone build targeting old linux kernels. It makes me unlikely
to want to use Semigroup more in git-annex, because the benefit of the
abstraction is swamped by the ugliness. I actually considered ripping out
all the Semigroup instances, but some are needed to use
optparse-applicative.
The problem, I think, is they made this transaction on too fast a timeline.
(Although ironically, work on it started in 2015 or earlier!)
In particular, Debian oldstable is not out of security support, and it's
not possible to follow the simpler workarounds documented on the wiki and
have it build on oldstable (because the semigroups package in it is too
old).
I have only tested this build with ghc 8.2.2, not the newer and older
versions that branches of the CPP support. So there could be typoes, we'll
see.

* migrate: Fix bug in migration between eg SHA256 and SHA256E,
that caused the extension to be included in SHA256 keys,
and omitted from SHA256E keys.
(Bug introduced in version 6.20170214)
* migrate: Check for above bug when migrating from SHA256 to SHA256
(and same for SHA1 to SHA1 etc), and remove the extension that should
not be in the SHA256 key.
* fsck: Detect and warn when keys need an upgrade, either to fix up
from the above migrate bug, or to add missing size information
(a long ago transition), or because of a few other past key related
bugs.

Prevent haskell http-client from decompressing gzip files, so downloads of
such files works the same as it used to with wget and curl.
Explicitly setting accept-encoding to "identity" is probably not needed,
but that's what wget sends (curl does not send the header), and since
http-client is trying to be excessively smart, it seems we need to set
hAcceptEncoding to something to prevent it from inserting its own,
and this seems better than some hack like "".

* move: --force was accidentially enabling two unrelated behaviors
since 6.20180427. The older behavior, which has never been well
documented and seems almost entirely useless, has been removed.
* copy: --force no longer does anything.
