* Added annex.resolvemerge configuration, which can be set to false to
disable the usual automatic merge conflict resolution done by git-annex
sync and the assistant.
* sync: Added --no-resolvemerge option.
Note that disabling merge conflict resolution is probably not a good idea
in a direct mode repo or adjusted branch. Since updates to both are done
outside the usual work tree, if it fails the tree is not left in a
conflicted state, and it would be hard to manually resolve the conflict.
Still, made annex.resolvemerge be supported in those cases for consistency.

When setting metadata of a file that did not exist, no error message was
displayed, unlike getting metadata and most other git-annex commands. Fixed
this oversight.
Note that, if the file exists but is not annexed, there's no error.
This is the same behavior as other git-annex commands.

There was documentation in 66285ca3d1,
but it was lost in the man page split.
I don't know if this --force is very useful. Considered removing it
instead..
* move --to=here moves from all reachable remotes to the local repository.
The output of move --from remote is changed slightly, when the remote and
local both have the content. It used to say:
move foo ok
Now:
move foo (from theremote...) ok
That was done so that, when move --to=here is used and the content is
locally present and also in several remotes, it's clear which remotes the
content gets dropped from.
Note that move --to=here will report an error if a non-reachable remote
contains the file, even if the local repository also contains the file. I
think that's reasonable; the user may be intending to move all other copies
of the file from remotes.
OTOH, if a copy of the file is believed to be present in some repository
that is not a configured remote, move --to=here does not report an error.
So a little bit inconsistent, but erroring in this case feels wrong.
copy --to=here came along for free, but it's basically the same behavior as
git-annex get, and probably with not as good messages in edge cases
(especially on failure), so I've not documented it.

See my comment. This only avoids the problem for -J; two git-annex
processes started at the same time could still both try to write to
.git/config and one fail. That would be very unlikely though, and it
doesn't really seem worth adding an additional layer of locking around
.git/config.

orElse is great, but was not the right thing to use here because
waitTakeLock could retry for other reasons than the lock being held,
which made tryTakeLock fail when it shouldn't.
Instead, move the code to tryTakeLock and implement waitTakeLock using
tryTakeLock and retry.
(Also, in runTransfer, when checkSaneLock fails, dropLock to avoid leaking a
lock handle.)

When built with concurrent-output 1.9, ssh password prompts will no longer
interfere with the -J display.
To avoid flicker, only done when ssh actually does need to prompt;
ssh is first run in batch mode and if that succeeds the connection is up
and no need to clear regions.

Cryptonite is faster and allocates less, and I want to get rid of
MissingH use.
Note that the new dependency on memory is free; it's a dependency of
cryptonite.

When ssh connection caching is enabled (and when GIT_ANNEX_USE_GIT_SSH is
not set), only one ssh password prompt will be made per host, and only one
ssh password prompt will be made at a time.
This also fixes a race in prepSocket's stale ssh connection stopping
when run with -J. It was possible for one thread to start a cached ssh
connection, and another thread to immediately stop it, resulting in excess
connections being made.

It takes a single key-value backend, rather than the unncessary and confusing list.
The old option still works if set.
Simplified some old old code too.

fsck already special-cased dead keys to make --all not report errors with
them, and it makes sense to also expand that to whereis. I think it makes
sense for dead keys to be skipped by all uses of --all, so mistakes can be
completely forgotten about and not come back to haunt us.
The speed impact of testing if the key is dead is negligible for fsck and
whereis, since they use the location log anyway and it gets cached.
This does slow down a few commands that support --all, in particular
metadata --all runs around 2x as slow. I don't think metadata
--all is often used though. It might slow down copy/move/mirror
--all and get --all.
log --all is not affected (does not use the normal --all machinery).
Dead keys will still be processed by --incomplete, --branch,
--failed, and --key. Although it would be unlikely for a dead key to
ave in incomplete or failed transfer. It seems to make perfect sense for
--branch to process keys on the branch, even if dead.
(fsck's special-casing of dead keys was left in, so if one of these options
causes a dead key to be fscked, there will be a nice message.)

Unlike git add -u, git annex add -u does not update the index for files
removed from the working tree. But then, "git add ." stages removals,
and "git annex add ." does not, so that's an existing divergence.
Seems that --update --batch would need to run git ls-files once per line of
batch input, which would surely be too slow, so just throw an error for
that.

This was never supported before. And it doesn't re-encrypt the
gcrypt repo to the new gcrypt-participants, but it does at least now not
crash, and set gcrypt-participants.

This is necessary because as feared, the extra -n parameter that git-annex
passes breaks uses of these environment variables that expect exactly the
parameters that git passes.
For example, see https://github.com/datalad/datalad/issues/1456
It would of course be possible to pre-close stdin before running ssh so not
needing the -n, and I think that would not even break ssh's password
caching. But it would probably involve a lot of work, possibly would need
to deal with some layering violations, and would be error-prone. The really
clean fix would be to make all the ssh stuff return a CreateProcess, which
could have the handle closed when appropriate, but that would be a large
reworing of the code base.

The former can be useful to make remotes that don't get fully synced with
local changes, which comes up in a lot of situations.
The latter was mostly added for symmetry, but could be useful (though less
likely to be).
Implementing `remote.<name>.annex-pull` was a bit tricky, as there's no one
place where git-annex pulls/fetches from remotes. I audited all
instances of "fetch" and "pull". A few cases were left not checking this
config:
* Git.Repair can try to pull missing refs from a remote, and if the local
repo is corrupted, that seems a reasonable thing to do even though
the config would normally prevent it.
* Assistant.WebApp.Gpg and Remote.Gcrypt and Remote.Git do fetches
as part of the setup process of a remote. The config would probably not
be set then, and having the setup fail seems worse than honoring it if it
is already set.
I have not prevented all the code that does a "merge" from merging branches
from remotes with remote.<name>.annex-pull=false. That could perhaps
be done, but it would need a way to map from branch name to remote name,
and the way refspecs work makes that hard to get really correct. So if the
user fetches manually, the git-annex branch will get merged, for example.
Anther way of looking at/justifying this is that the setting is called
"annex-pull", not "annex-merge".
