Missed this when implementing it because of the default case catching
the new constructor. So, removed that default case to make sure
future types of adjusted branches don't make the same mistake.
Complicated by git-annex addurl --fast which adds the file whose content
is not present, so it needs to stay unlocked when on such a branch.

34a535ebea broke the test suite.
Getting a file started failing in one case, because the annex object did
not have its inode cached, so was not trusted to be unmodified.
This adds something very similar to what was added to linkAnnex
in commit 2e9341a47d -- if there are not
yet any inodes cached for a key, add the inode of the annex object when
adding the inode of the unlocked file.
Feels like this should be handled in a more principled way. How
do we know the addInodeCaches call in getMoveRaceRecovery just above
this change is currently correct? It doesn't add the annex object inode
cache. Ah well, maybe sometime when I've not had my entire evening eaten
by a reversion that the test suite caught as I was cooking dinner.
Avoids the smudge --clean filter failing because URL keys do not support
genKey. Instead the modified content will be added using the default
backend.

This avoids the smudge --clean filter failing on the URL keys.
git checkout runs the post-checkout hook, which runs smudge --update.
That populates all the pointer files, but it neglected to store their inode
caches in the keys db. With that done, and the keys db flushed before
smudge --clean gets run (by restagePointerFile), the isUnmodifiedCheap
check can tell the file is not modified, so will not try to re-ingest it,
which does not work with URL keys because they do not support genKey.
It also seems possible that the isUnmodifiedCheap was also failing for
non-URL keys, which would cause them to be re-ingested, leading to a lot of
extra work. I have not verified that, but don't see why it wouldn't have
happened. So this probably also speeds up checking out adjusted branches.

Configuring chunking and encryption for a git remote has no effect, so
skip testing those variants in the TestRemote call.
It would be better if TestRemote itself could do this, but it
doesn't seem possible there. There is no way to look at a Remote and
tell if it supports chunking or encryption.
Note that, while the test suite displays output as it it's testing
exporting, it actually skips doing anything for the tests when run on
the git remote. So at least does not waste time even though the output
is not ideal.

Since unconsidered use of trusted repositories can lead to data loss.
Trusted has always been this way, but it used to be acceptable for
git-annex to be set up so that data could be lost without using --force,
and most or all other ways that can happen have already been eliminated.

This is conceptually very simple, just making a 1 that was hard coded be
exposed as a config option. The hard part was plumbing all that, and
dealing with complexities like reading it from git attributes at the
same time that numcopies is read.
Behavior change: When numcopies is set to 0, git-annex used to drop
content without requiring any copies. Now to get that (highly unsafe)
behavior, mincopies also needs to be set to 0. It seemed better to
remove that edge case, than complicate mincopies by ignoring it when
numcopies is 0.

* add: Significantly speed up adding lots of non-large files to git,
by disabling the annex smudge filter when running git add.
* add --force-small: Run git add rather than updating the index itself,
so any other smudge filters than the annex one that may be enabled will
be used.
Especially from borg, where the content identifier logs
all end up being the same identical file!
But also, for other imports, the location tracking logs can,
in some cases, be identical files.
Bonus optimisation: Avoid looking up (and parsing when set)
GIT_ANNEX_VECTOR_CLOCK env var every time a log is written to.
Although the lookup does happen at startup even when no
log will be written now.
May actually work now.
Note that, importKey now has to add the size to the key if it's supposed
to have size. Remote.Directory relied on the importer adding the size,
which is no longer done, so it was changed; it was the only one.
This way, importKey does not need to behave differently between regular
and thirdpartypopulated imports.
These don't have importTree in their config, because they don't support
tree import, but they do still support import, and do not support export
or key/value modification.
This is to support, eg a borg repo as a special remote, which is
populated not by running git-annex commands, but by using borg. Then
git-annex sync lists the content of the remote, learns which files are
annex objects, and treats those as present in the remote.
So, most of the import machinery is reused, to a new purpose. While
normally importtree maintains a remote tracking branch, this does not,
because the files stored in the remote are annex object files, not
user-visible filenames. But, internally, a git tree is still generated,
of the files on the remote that are annex objects. This tree is used
by retrieveExportWithContentIdentifier, etc. As with other import/export
remotes, that the tree is recorded in the export log, and gets grafted
into the git-annex branch.
importKey changed to be able to return Nothing, to indicate when an
ImportLocation is not an annex object and so should be skipped from
being included in the tree.
It did not seem to make sense to have git-annex import do this, since
from the user's perspective, it's not like other imports. So only
git-annex sync does it.
Note that, git-annex sync does not yet download objects from such
remotes that are preferred content. importKeys is run with
content downloading disabled, to avoid getting the content of all
objects. Perhaps what's needed is for seekSyncContent to be run with these
remotes, but I don't know if it will just work (in particular, it needs
to avoid trying to transfer objects to them), so I skipped that for now.
(Untested and unused as of yet.)

Don't want to try to use these remotes as key/value remotes, which will
surely fail. It only recently became possible for importtree to be set
w/o exporttree, so before this code was ok.
(cherry picked from commit 97599cb0f7f4115aa5a3e81a91ee3d1d6c52dc84)
In cd1676d604, it stopped using that to avoid surprising behavior
when the location log and remote content were out of sync.
But, it seems that may have changed some behavior users relied on as
well, and also Remote.hasKeyCheap should be faster than checking then
location log.
So, try Remote.hasKeyCheap first, and only if it does not have the key,
fall back to checking the location log. If the location log still thinks
it's present, go ahead and try to get it, so the user will see a failure
rather than silently skipping a file what whereis says is on the remote.
This does make slightly slower the case where the remote does not have
the key, and location log and Remote.hasKeyCheap agree, since it now
checks both. But only 1 stat slower.
This is common in some feeds, which might mix some items with enclosures,
with others that link to posts or whatever. Before this, it would try to
use youtube-dl and fail, or if youtube-dl was not allowed, it would
incorrectly complain that an url was supported by youtube-dl.
MatchingKey is not the thing to use when matching on actual worktreee
files.
Fix reversion in 8.20201116 that made include= and exclude= in
preferred/required content expressions match a path relative to the current
directory, rather than the path from the top of the repository.
Done on unix, could not implement it on windows quite.
The signal library gets part of the way needed for windows.
But I had to open https://github.com/pmlodawski/signal/issues/1 because
it lacks raiseSignal.
Also, I don't know what the equivilant of getProcessGroupIDOf is on
windows. And System.Process does not provide a way to send any signal to
a process group except for SIGINT.

All callers adjusted to update it themselves.
In Command.ReKey, and Command.SetKey, the cleanup action already did,
so it was updating the log twice before.
This fixes a bug when annex.stalldetection is set, as now
Command.Transferrer can skip updating the location log, and let it be
updated by the calling process.
Rather than using Read/Show, which would force me to preserve data types
into the future.
I considered just deriving json and sending that, but I don't much like
deriving json with data types that have named constructors (like Key
does) because again it locks in data type details.
So instead, used SimpleProtocol, with a fairly complex and unreadable
protocol. But it is as efficient as the p2p protocol at least, and as
future proof.
(Writing my own custom json instances would have worked but I thought
of it too late and don't want to do all the work twice. The only real
benefit might be that aeson could be faster.)
Note that, when a new protocol request type is added later, git-annex
trying to use it will cause the git-annex transferrer to display a
protocol error message. That seems ok; it would only happen if a new
git-annex found an old version of itself in PATH or the program
file. So it's unlikely, and all it can do anyway is display an error.
(The error message could perhaps be improved..)

This is to avoid breakage when upgrading or downgrading git-annex with a
process running that uses the interface. It's better to keep the
compatability code for a few years than worry about such breakage.

Seems to work! Even progress bars. Have not tested prompting or various

transferkeys had to be made to operate in different modes for the
Assistant and Annex monads. A bit ugly, but it did relegate that
really ugly Database.Keys.closeDb in transferkeys to only the assistant
code path.

This is groundwork for using git-annex transferkeys to run transfers,
in order to allow stalled transfers to be interrupted and retried.
The new upload and download are closer to what git-annex transferkeys
does, so the plan is to make them use it.
Then things that were left using upload' and download' won't recover
from stalls. Notably, that includes import and export. But
at least get/move/copy will be able to. (Also the assistant hopefully,
but not yet.)

That seems to be the last thing needed for message serialization.
Although it's only used in the assistant currently, so hard to tell if I
forgot something.
At this point, it should be possible to start using transferkeys
when performing transfers, which will allow killing a transferkeys
process if a transfer times out or stalls. But that's for another day.

Necessarily threw out the old protocol, so if an old git-annex assistant
is running, and starts a transferkeys from the new git-annex, it would
fail. But, that seems unlikely; the assistant starts up transferkeys
processes and then keeps them running. Still, may need to test that
scenario.
The new protocol is simple read/show and looks like this:
TransferRequest Download (Right "origin") (Key {keyName = "f8f8766a836fb6120abf4d5328ce8761404e437529e997aaa0363bdd4fecd7bb", keyVariety = SHA2Key (HashSize 256) (HasExt True), keySize = Just 30, keyMtime = Nothing, keyChunkSize = Nothing, keyChunkNum = Nothing}) (AssociatedFile (Just "foo"))
TransferOutput (ProgressMeter (Just 30) (MeterState {meterBytesProcessed = BytesProcessed 0, meterTimeStamp = 1.6070268727892535e9}) (MeterState {meterBytesProcessed = BytesProcessed 30, meterTimeStamp = 1.6070268728043e9}))
TransferOutput (OutputMessage "(checksum...) ")
TransferResult True
Granted, this is not optimally fast, but it seems good enough, and is
probably nearly as fast as the old protocol anyhow.
emitSerializedOutput for ProgressMeter is not yet implemented. It needs
to somehow start or update a progress meter. There may need to be a new
message that allocates a progress meter, and then have ProgressMeter
update it.

Added annex.adjustedbranchrefresh git config to update adjusted branches
set up by git-annex adjust --unlock-present/--hide-missing.
Note, in a few cases, I was not able to make the adjusted branch
be updated in calls to moveAnnex, because information about what
file corresponds to a key is not available. They are:
* If two files point to one file, then eg, `git annex get foo` will
update the branch to unlock foo, but will not unlock bar, because it
does not know about it. Might be fixable by making `git annex get
bar` do something besides skipping bar?
* git-annex-shell recvkey likewise (so sends over ssh from old versions
of git-annex)
* git-annex setkey
* git-annex transferkey if the user does not use --file
* git-annex multicast sends keys with no associated file info
Doing a single full refresh at the end, after any incremental refresh,
will deal with those edge cases.
An --unlock-present branch reverses back to a branch where
all files that get modified or renamed become locked, even if they were
originally unlocked. This is the same that reversing a --unlock branch
works, and the new name makes that commonality more clear.
