This is groundwork for nested seek loops, eg seeking over all files and
then performing commandActions on a list of remotes, which can be done
concurrently.

Added --json-error-messages option, which includes error messages in the
json output, rather than outputting them to stderr.
The actual rediretion of errors is not implemented yet, this is only
the docs and option plumbing.

This is the same as running git annex reinject --known, followed by
git-annex import. The advantage to having it in one command is that it
only has to hash each file once; the two commands have to
hash the imported files a second time.

import: --deduplicate and --skip-duplicates were implemented inneficiently;
they unncessarily hashed each file twice. They have been improved to only
hash once.
The new approach is to lock down (minimally) and hash files, and then
reuse that information when importing them.
This was rather tricky, especially in detecting changes to files while
they are being imported.
The output of import changed slightly. While before it silently skipped
over files with eg --skip-duplicates, now it shows each file as it starts
to act on it. Since every file is hashed first thing, it would otherwise
not be clear what file import is chewing on. (Actually, it wasn't clear
before when any of the duplicates switches were used.)

Before, only content known to be present somewhere was considered a
duplicate. Now, any content that has been annexed before will be considered
a duplicate, even if all annexed copies of the data have been lost.
Note that --clean-duplicates and --deduplicate still check numcopies,
so won't delete duplicate files unless there's an annexed copy.
This makes import use the same method as reinject --known.
The man page already said that duplicate meant "its content is either
present in the local repository already, or git-annex knows of another
repository that contains it, or it was present in the annex before but has
been removed now". So, this is really only bringing the implementation into
line with the man page.

ghc 8 added backtraces on uncaught errors. This is great, but git-annex was
using error in many places for a error message targeted at the user, in
some known problem case. A backtrace only confuses such a message, so omit it.
Notably, commands like git annex drop that failed due to eg, numcopies,
used to use error, so had a backtrace.

importfeed just calls addurl functions, so inherits this from it.
Note that addurl still generates a temp file, and uses that key to download
the file. It just adds it to the work tree at the end when the file is small.
There should be no behavior changes in this commit, it just adds a more
expressive data type and adjusts code that had been passing around a [UUID]
or sometimes a Maybe Remote to instead use [VerifiedCopy].
Although, since some functions were taking two different [UUID] lists,
there's some potential for me to have gotten it horribly wrong.
This is a work in progress. It compiles and is able to do basic command
dispatch, including git autocorrection, while using optparse-applicative
for the core commandline parsing.
* Many commands are temporarily disabled before conversion.
* Options are not wired in yet.
* cmdnorepo actions don't work yet.
Also, removed the [Command] list, which was only used in one place.
--deduplicate, --skip-duplicates, and --clean-duplicates still checksum the
file twice, the first time to determine if it's a duplicate. This cannot be
easily merged with the checksumming done to add the file, since the file
needs to be locked down before that second checksum is taken.

Unfortunately, this caused breakage on Windows, and possibly elsewhere,
because parentDir and takeDirectory do not behave the same when there is a
trailing directory separator.
parentDir is less safe than takeDirectory, especially when working
with relative FilePaths. It's really only useful in loops that
want to terminate at /

This fixes all instances of " \t" in the code base. Most common case
seems to be after a "where" line; probably vim copied the two space layout
of that line.
Done as a background task while listening to episode 2 of the Type Theory
podcast.
This avoids cp -a overriding the default mode acls that the user might have
set in a git repository.
With GNU cp, this behavior change should not be a breaking change, because
git-anex also uses rsync sometimes in the same situation, and has only ever
preserved timestamps when using rsync.
Systems without GNU cp will no longer use cp -a, but instead just cp.
So, timestamps will no longer be preserved. Preserving timestamps when
copying between repos is not guaranteed anyway.
Closes: #729757
I've been disliking how the command seek actions were written for some
time, with their inversion of control and ugly workarounds.
The last straw to fix it was sync --content, which didn't fit the
Annex [CommandStart] interface well at all. I have not yet made it take
advantage of the changed interface though.
The crucial change, and probably why I didn't do it this way from the
beginning, is to make each CommandStart action be run with exceptions
caught, and if it fails, increment a failure counter in annex state.
So I finally remove the very first code I wrote for git-annex, which
was before I had exception handling in the Annex monad, and so ran outside
that monad, passing state explicitly as it ran each CommandStart action.
This was a real slog from 1 to 5 am.
Test suite passes.
Memory usage is lower than before, sometimes by a couple of megabytes, and
remains constant, even when running in a large repo, and even when
repeatedly failing and incrementing the error counter. So no accidental
laziness space leaks.
Wall clock speed is identical, even in large repos.

Previous test did not notice if there is a dangling symlink.
Also, if a directory exists with the same name as the imported file, that
cannot work, so don't let --force have an effect.
Note that the hash backends were made to stop printing a (checksum..)
message as part of this, since it showed up without a file when deciding
whether to act on a file. Should have probably removed that message a while
ago anyway, I suppose.
Note that --deduplicate currently checksums each file twice,
once to see if it's a known key, and once when importing it.
Perhaps this could be revisited and the extra checksum gotten rid of,
at the cost of not locking down the file when adding it.
