fix --branch combined with --unlocked or --locked
Since it's using git ls-tree anyway, can just look at the file modes to see
if they're unlocked or are symlinks.

Prevent combinations of options such as --all with --include
Previously such nonsensical combinations always treated the matching option
as if it didn't match.

For now, made find --branch refuse matching options that need a
filename, because one is not provided to them in a way they'll use.
There's an open bug report to support it, but making it error out is
better than the old behavior of not finding what it was asked to.

Also, made --mimetype combined with eg --all work, by looking at the
object file when operating on keys.

incremental checksum for local remotes
This benchmarks only slightly faster than the old git-annex. Eg, for a 1
gb file, 14.56s vs 15.57s. (On a ram disk; there would certianly be
more of an effect if the file was written to disk and didn't stay in
cache.)

Commenting out the updateIncremental calls make the same run in 6.31s.
May be that overhead in the implementation, other than the actual
checksumming, is slowing it down. Eg, MVar access.

(I also tried using 10x larger chunks, which did not change the speed.)

Bugfix: fsck --from a ssh remote did not actually check that the content on the remote is not corrupted
Changing to the P2P protocol broke this, because preseedTmp copies
the local copy of the object to the temp file, and then the P2P transfer
sees the right length file and uses it as-is.

When git-annex-shell is too old and rsync is used, it did verify the
content, and when the local repo does not have the object it did verify the
content.

incremental checksum on download from ssh or p2p
Checksum as content is received from a remote git-annex repository, rather
than doing it in a second pass.

Not tested at all yet, but I imagine it will work!

Not implemented for any special remotes, and also not implemented for
copies from local remotes. It may be that, for local remotes, it will
suffice to use rsync, rely on its checksumming, and simply return Verified.
(It would still make a checksumming pass when cp is used for COW, I guess.)

Tahoe: Avoid verifying hash after download, since tahoe does sufficient verification itself
See my comment in the next commit for some details about why
Verified needs a hash with preimage resistance. As far as tahoe goes,
it's fully cryptographically secure.

I think that bup could also return Verified. However, the Retriever
interface does not currenly support that.

avoid making absolute git remote path relative
When a git remote is configured with an absolute path, use that path,
rather than making it relative. If it's configured with a relative path,
use that.

Git.Construct.fromPath changed to preserve the path as-is,
rather than making it absolute. And Annex.new changed to not
convert the path to relative. Instead, Git.CurrentRepo.get
generates a relative path.

A few things that used fromAbsPath unncessarily were changed in passing to
use fromPath instead. I'm seeing fromAbsPath as a security check,
while before it was being used in some cases when the path was
known absolute already. It may be that fromAbsPath is not really needed,
but only git-annex-shell uses it now, and I'm not 100% sure that there's
not some input that would cause a relative path to be used, opening a
security hole, without the security check. So left it as-is.

Test suite passes and strace shows the configured remote url is used
unchanged in the path into it. I can't be 100% sure there's not some code
somewhere that takes an absolute path to the repo and converts it to
relative and uses it, but it seems pretty unlikely that the code paths used
for a git remote would call such code. One place I know of is gitAnnexLink,
but I'm pretty sure that git remotes never deal with annex symlinks. If
that did get called, it generates a path relative to cwd, which would have
been wrong before this change as well, when operating on a remote.

suggest when user may want annex.stalldetection
When annex.stalldetection is not enabled, and a likely stall is detected,
display a suggestion to enable it.

Note that the progress meter display is not taken down when displaying
the message, so it will display like this:

	0%    8 B                 0 B/s
	  Transfer seems to have stalled. To handle stalling transfers, configure annex.stalldetection
	0%    10 B                0 B/s

Although of course if it's really stalled, it will never update
again after the message. Taking down the progress meter and starting
a new one doesn't seem too necessary given how unusual this is,
also this does help show the state it was at when it stalled.

Use of uninterruptibleCancel here is ok, the thread it's canceling
only does STM transactions and sleeps. The annex thread that gets
forked off is separate to avoid it being canceled, so that it
can be joined back at the end.

A module cycle required moving from dupState the precaching of the
remote list. Doing it at startConcurrency should cover all the cases
where the remote list is used in concurrent actions.

addon commands
Seems only fair, that, like git runs git-annex, git-annex runs
git-annex-foo.

Implementation relies on O.forwardOptions, so that any options are passed
through to the addon program. Note that this includes options before the
subcommand, eg: git-annex -cx=y foo

Unfortunately, git-annex eats the --help/-h options.
This is because it uses O.hsubparser, which injects that option into each
subcommand. Seems like this should be possible to avoid somehow, to let
commands display their own --help, instead of the dummy one git-annex
displays.

The two step searching mirrors how git works, it makes finding
git-annex-foo fast when "git annex foo" is run, but will also support fuzzy
matching, once findAllAddonCommands gets implemented.

fix handling of implicit and before parens
Fix an oddity in matching options and preferred content expressions such as
"foo (bar or baz)", which was incorrectly handled as if it were "(foo or
bar) and baz)" rather than the intended "foo and (bar or baz)"

Seemed like a change to consume should be able to handle this case
better, but I was having trouble writing it that way, so instead added
a separate pass that inserts the implicit ands explicitly. Also added
several test cases to make sure versions with and without explicit ands
generate the same.

When adding files to an adjusted branch set up by --unlock-present, add them unlocked, not locked
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.

adjust: Fix some bad behavior when unlocked files use URL keys.
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.

fix a bug that prevented git-annex init from working in a submodule
This is probably a reversion, but not sure what caused it. By the time
Annex.Init runs fixupUnusualReposAfterInit, another git-annex process has
at least sometimes already done the necessary fixups. (Eg, one run
indirectly by a git command.) But since the Repo is cached, it doesn't
realize and does them again. So, avoid crashing when git config --unset
fails.

omit inode from ContentIdentifier for directory special remote
Directory special remotes with importtree=yes now avoid unncessary overhead
when inodes of files have changed, as happens whenever a FAT filesystem
gets remounted.

A few unusual edge cases of modifications won't be detected and
imported. I think they're unusual enough not to be a concern. It would
be possible to add a config setting that controls whether to compare
inodes too, but does not seem worth bothering the user about currently.

I chose to continue to use the InodeCache serialization, just with the
inode zeroed. This way, if I later change my mind or make it
configurable, can parse it back to an InodeCache and operate on it. The
overhead of storing a 0 in the content identifier log seems worth it.

There is a one-time cost to this change; all directory special remotes
with importtree=yes will re-hash all files once, and will update the
content identifier logs with zeroed inodes.

avoid crashing when there are remotes using unparseable urls
Including the non-standard URI form that git-remote-gcrypt uses for rsync.

Eg, "ook://foo:bar" cannot be parsed because "bar" is not a valid port
number. But git could have a remote with that, it would try to run
git-remote-ook to handle it. So, git-annex has to allow for such things,
rather than crashing.

Behavior change: --trust option no longer overrides trust
Since that can lead to data loss, which should never be enabled by an
option other than --force.

I suppose that using --trust was in some situation, safer than --force,
because it doesn't entirely disable checking for data loss, but only
disables checking involving data that is on the specified repository.
But it seems better to be able to say that data loss only happens with
--force.

Since unconsidered use of trusted repositories can lead to data loss.

Trusted has always been this way, but it used to be acceptable for

mincopies
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.

fix --time-limit
It got broken in several ways by the streaming seeking optimisations
around version 8.20201007.

Moved time limit checking out of the matcher, which was a hack in the
first place. So everywhere that uses Limit.getMatcher needs to check
time limit. Well, almost everywhere. Command.Info uses it, but it does
not make sense to time limit getting info. And Command.MultiCast uses it
just to build up a list of files that then get passed to a command, so
it would never have hit the timeout in a useful way.

This implementation is a little more expensive when at time limit than
necessary, since it continues seeking only to discard everything after the
time limit. I did try making it close the file handles to force a faster
shutdown, but that didn't work and hung. Could certianly be improved
somehow, but seeking is probably not the expensive bit when a time limit
is hit, so this seems acceptable for now.
