webdav: Fix lack of url-escaping of filenames.
inDAVLocation does not url-escape, and so exporting a filename with spaces
to box.com at least resulted in a error 400.

It might also have affected storing keys on a webdav remote, if the key
contained a space or other problem character. Pretty unlikely.

I emailed Clint about the inDAVLocation gotcha, but seems best to fix it
here.

deal with box.com horrible infinite redirect behavior
webdav: Checking if a non-existent file is present on Box.com triggered a
bug in its webdav support that generates an infinite series of redirects.

It seems to redirect foo to foo/ to foo/index.php to
foo/index.php/index.php ... Why a webdav endpoint would behave this way
who knows.

Deal with such problems by assuming such behavior means the file is not
present.

Can't simply disable following redirects, because the webdav endpoint could
legitimately be redirected to a new endpoint. So, when this happens
10 redirects have to be followed, before it gives up and assumes this means
the file does not exist.

export to webdav
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?

stop warning about removals from IA
In a test, I uploaded a pdf, and several files were derived from it.
After removing the pdf, the derived files went away after approximatly
half an hour. This window does not seem worth warning about every time.
Documented it in the tip.

S3: Allow removing files from IA, but warn about derived versions potentially still existing there.
Removal works, only derives are a potential issue, so allow removing
with a warning. This way, unexporting a file works, and behavior is
consistent with IA remotes whether or not exporttree=yes.

Also tested exporting filenames containing unicode, spaces, underscores.
All worked, despite the IA's faq saying it doesn't.

S3 export (untested)
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.

git-annex.cabal: Deal with breaking changes in Cabal 2.0
https://github.com/haskell/cabal/issues/4655

This means that when a module is conditionally imported via ifdef
depending on the OS or build flags, the cabal file has to mirror the
same logic there to only list the module then.

Since there are lots of OS's and lots of combinations of build flags
here, it's rather difficult to know if the cabal file has been completelty
correctly updated to match the source code.

So I am very unhappy with needing to update things in two places. I've
only tested this on linux with most build flags enables; this will
probably need significant time and testing to catch every cabal file
tweak that this change to Cabal requires. And it will be a continual
source of compile failures going forward when the code is modified and
the cabal file not also updated.

DRY DRY DRY, I repeat myself, but: DRY! Sigh..

(Also, had to remove all Build.* that are standalone programs from the
Other-Modules list, because since cabal passes those modules to ghc when
building git-annex, it complains that they use module Main. Those
modules are only used when building with the Makefile anyway, so this
change shouldn't break anything.)

avoid the dashed ssh hostname class of security holes
Security fix: Disallow hostname starting with a dash, which would get
passed to ssh and be treated an option. This could be used by an attacker
who provides a crafted ssh url (for eg a git remote) to execute arbitrary
code via ssh -oProxyCommand.

No CVE has yet been assigned for this hole.
The same class of security hole recently affected git itself,
CVE-2017-1000117.

Method: Identified all places where ssh is run, by git grep '"ssh"'
Converted them all to use a SshHost, if they did not already, for
specifying the hostname.

SshHost was made a data type with a smart constructor, which rejects
hostnames starting with '-'.

Note that git-annex already contains extensive use of Utility.SafeCommand,
which fixes a similar class of problem where a filename starting with a
dash gets passed to a program which treats it as an option.

external: nice error message for keys with spaces in their name
External special remotes will refuse to operate on keys with spaces in
their names. That has never worked correctly due to the design of the
external special remote protocol. Display an error message suggesting
migration.

Not super happy with this, but it's a pragmatic solution. Better than
complicating the external special remote interface and all external special
remotes.

Note that I only made it use SafeKey in Request, not Response. git-annex
does not construct a Response, so that would not add any safety. And
presumably, if git-annex avoids feeding any such keys to an external
special remote, it will never have a reason to make a Response using such a
key. If it did, it would result in a protocol error anyway.

There's still a Serializeable instance for Key; it's used by P2P.Protocol.
There, the Key is always in the final position, so it's ok if it contains
spaces.

Note that the protocol documentation has been fixed to say that the File
may contain spaces. One way that can happen, even though the Key can't,
is when using direct mode, and the work tree filename contains spaces.
When sending such a file to the external special remote the worktree
filename is used.

add annex-ignore-command and annex-sync-command configs
Added remote configuration settings annex-ignore-command and
annex-sync-command, which are dynamic equivilants of the annex-ignore
and annex-sync configurations.

For this I needed a new DynamicConfig infrastructure. Its implementation
should be as fast as before when there is no dynamic config, and it caches
so shell commands are only run once.

Note that annex-ignore-command exits nonzero when the remote should be ignored.
While that may seem backwards, it allows using the same command for it as
for annex-sync-command when you want to disable both.

test: Avoid most situations involving failure to delete test directories
By forking a worker process and only deleting the test directory once it exits.

This way, if a test leaves files open, they'll get closed when the worker
exits, so avoiding failure to delete open files on Windows, and failure to
delete directories due to NFS lock files.

If a test leaves a git worker process running, the closed pipes should
cause the worker to exit too, also avoiding the problem there. The 10
second sleep ought to give plenty of time for such worker processes to
exit, although this is of course a race.

Finally, even if test directory fails to be deleted still,
it won't appear as if the last test in the test suite failed; the error
will be displayed at the very end.

Added GIT_ANNEX_VECTOR_CLOCK environment variable
Can be used to override the default timestamps used in log files in the
git-annex branch. This is a dangerous environment variable; use with
caution.

Note that this only affects writing to the logs on the git-annex branch.
It is not used for metadata in git commits (other env vars can be set for
that).

There are many other places where timestamps are still used, that don't
get committed to git, but do touch disk. Including regular timestamps
of files, and timestamps embedded in some files in .git/annex/, including
the last fsck timestamp and timestamps in transfer log files.

A good way to find such things in git-annex is to get for getPOSIXTime and
getCurrentTime, although some of the results are of course false positives
that never hit disk (unless git-annex gets swapped out..)

So this commit does NOT necessarily make git-annex comply with some HIPPA
privacy regulations; it's up to the user to determine if they can use it in
a way compliant with such regulations.

Benchmarking: It takes 0.00114 milliseconds to call getEnv
"GIT_ANNEX_VECTOR_CLOCK" when that env var is not set. So, 100 thousand log
files can be written with an added overhead of only 0.114 seconds. That
should be by far swamped by the actual overhead of writing the log files
and making the commit containing them.

zsh and fish completions
optparse-applicative-0.14.0.0 adds support for these, so have the
Makefile install their scripts when built with it.

CmdLine/GitAnnex/Options.hs now uses action "file" in cmdParams,
which affects the bash and zsh completions, letting them complete
filenames for subcommands that use that. This is not needed for
bash, since bash-completion.bash enables -o bashdefault, which
lets it complete filenames too. But it does not seem to break the bash
completions. It is needed for zsh; the zsh completion otherwise
does not complete filenames. The fish completion will always complete
filenames no matter what. Messy.

assistant: Merge changes from refs/remotes/foo/master into master.
Previously, only sync branches were merged. This makes regular git push
into a repository watched by the assistant auto-merge.

While this does hardcode an assumption about what the remote tracking
branch is named, which some unusual git configurations won't match,
git-annex sync already made the same assumption.

Also, changed behavior when a tracking branch like
refs/remotes/synced/not/master is received. When on the master branch,
that used to get merged into it, but it's the tracking branch for
not/master, so should only be merged in when on the not/master branch.

configuration to disable automatic merge conflict resolution
* 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.

error when metadata set is used with file that does not exist
When setting metadata of a file that did not exist, no error message was

move --to=here
* 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.

Avoid concurrent git-config setting problem when running concurrent threads.
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.

Fix transfer log file locking problem when running concurrent transfers.
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.)

Keys marked as dead are now skipped by --all.
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.)
