Avoid performing repository fixups for submodules and git-worktrees
when there's a .noannex file that will prevent git-annex from being
used in the repository.
This change is ok as long as the .noannex file is really going to prevent
git-annex from being used. But, init --force could override the file.
Which would result in the repo being initialized without the fixups
having run.
To avoid that situation decided to change init, to not let --force be used
to override a .noannex file. Instead the user can just delete the file.
This makes --version=6 still work, despite v6 not being in
supportedVersions. Which is useful for scripts that use it.
I didn't document it on the man page, because it's indistinguishable
from an automatic upgrade after initting as v6.
Install new git hooks in this version.
This does beg the question of what to do if git later gets eg a
post-smudge hook, that could run git-annex smudge --update. I think the
thing to do in that case would be to make git-annex smudge --update
install the new hooks. That way, as the user uses git-annex, the hook
would be created pretty quickly and without needing any extra syscalls
except for when git-annex smudge --update is called.
I considered doing something like that for installation of the
post-checkout and post-merge hooks, which would have avoided the need
for v7. But the only place it was cheap to do it would be in git-annex smudge
which could cheaply notice that smudge.log didn't exist yet and so know
the hooks needed to be installed. But since smudge used to populate pointer
files, it would be quite surprising if a single git checkout/merge failed
to update the work tree, and so that idea didn't work out.
The other reason for v7 is psychological -- users don't need to worry
about whether they might be running an old version of git-annex that
doesn't support their v7 repository very well. And bug reports about
"v6" have gotten a bit of a bad association in my head since they often
hit one of the known limitations and didn't realize it was experimental.
newtyped RepoVersion Int to avoid needing 2 comparisons in
versionSupportsUnlockedPointers etc. Also it's just nicer.

A top-level .noannex file will prevent git-annex init from being used in a
repository. This is useful for repositories that have a policy reason not
to use git-annex. The content of the file will be displayed to the user who
tries to run git-annex init.
This also affects git annex reinit and initialization via the webapp.
It does not affect automatic inits, when there's a sibling git-annex branch
already.

Clean up some uses of showStart with "" for the file,
or in some cases, a non-filename description string. That would
generate bad json, although none of the commands doing that
supported --json.
Using "" for the file resulted in output like "foo rest";
now the extra space is eliminated.

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.
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.

This is my own damn fault for not making UUID a real type, and then relying
on the type checker to ensure my refactoring was correct -- which it wasn't!
I should probably add code to clean up bogus entries in the uuid.log, but
right now I want to get the fix out there to prevent people experiencing
this bug.
I should also make UUID a real data type.
This new approach allows filtering out checks from the default set that are
not appropriate for a command, rather than having to list every check
that is appropriate. It also reduces some boilerplate.
Haskell does not define Eq for functions, so I had to go a long way around
with each check having a unique id. Meh.
These were a mistake, they make the type signatures harder to read and
less flexible. The CommandSeek, CommandStart, CommandPerform, and
CommandCleanup types were a good idea, but composing them with the
parameters expected is going too far.
when a git repository is first being created. Clones will automatically
notice that git-annex is in use and automatically perform a basic
initalization. It's still recommended to run "git annex init" in any
clones, to describe them.
Do not set annex.version whenever any command is run. Just do it in init.
This ensures that, if a repo has annex.version=3, it has a git-annex
branch, so we don't have to run a command every time to check for the
branch.
Remove the old ad-hoc logic for v0 and v1, to simplify version checking.
stop changing gitattributes on init
create git-annex branch on init
ugly special case for init in a bare repository goes away, yay!
git annex init is also faster, at least in a large existing repo, as
it does not need to run the slow 'git add'
Rename Locations functions for better consitency, and make their values
more consistent too.
Used </> rather than manually building paths. There are still more places
that manually do so, but are tricky, due to the behavior of </> when
the second FilePath is absolute. So I only changed places where
it obviously was relative.
