The initTests have to be run once per part, and a point of diminishing
returns can be reached where more work is being done to set up for 1 or
2 tests than to run them.
This is better than a hard cap of -J8 or so, because it lets other
things than these particular tests still be parallelized at -J16.

WIP: This is mostly complete, but there is a problem: createDirectoryUnder
throws an error when annex.dbdir is set to outside the git repo.
annex.dbdir is a workaround for filesystems where sqlite does not work,
due to eg, the filesystem not properly supporting locking.
It's intended to be set before initializing the repository. Changing it
in an existing repository can be done, but would be the same as making a
new repository and moving all the annexed objects into it. While the
databases get recreated from the git-annex branch in that situation, any
information that is in the databases but not stored in the branch gets
lost. It may be that no information ever gets stored in the databases
that cannot be reconstructed from the branch, but I have not verified
that.

test: When limiting tests to run with -p, work around tasty limitation by
automatically including dependent tests.
This fixes a reversion because it didn't used to use dependencies and
forced tasty to run the init tests first. That changed when parallelizing
the test suite.
It will sometimes do a little more work than strictly required,
because it adds init tests deps when limited to eg quickcheck tests,
which don't depend on them. But this only adds a few seconds work.

If the temp directory can somehow contain a hard link, it changes the
mode, which affects all other hard linked files. So, it's too unsafe
to use everywhere in git-annex, since hard links are possible in
multiple ways and it would be very hard to prove that every place that
uses a temp directory cannot possibly put a hard link in it.
Added a call to removeDirectoryForCleanup to test_crypto, which will
fix the problem that commit 17b20a2450
was intending to fix, with a much smaller hammer.

Dependency issues were looking difficult to support tasty-1.2 with that
build. Not using `after` only affects rerunning and limiting tests,
since tasty's concurrency is not used, so this build will just not
support that.
We are probably nearing end of life on this build; it also doesn't
support git-lfs or http-client-restricted. The 2.6.32 kernel it supports
is at this point 13 years old, and stopped being supported by linux LTS
developers 10 years ago. It was supported by RHEL 6.10 through November
2020. At this point, no new hardware should be shipping with this
kernel, but that probably does not stop certian embedded vendors from
shipping it. And there is certainly some hardware still using it. But
the returns from supporting it are diminishing, and the quality of the
build for it is also diminishing.

Default to the number of CPU cores, which seems about optimal
on my laptop. Using one more saves me 2 seconds actually.
Better packing of workers improves speed significantly.
In 2 tests runs, I saw segfaulting workers despite my attempt
to work around that issue. So detect when a worker does, and re-run it.
Removed installSignalHandlers again, because I was seeing an
error "lost signal due to full pipe", which I guess was somehow caused
by using it.

Unit tests are the main bulk of runtime, so splitting them into 2 or 3
parts should help.
For now, the number of parts is still 1, because on my 4 core laptop,
2 was a little bit slower, and 3 slower yet. However, this probably does
vary based on the number of cores, so needs to be revisited, and perhaps
made dynamic.
Since each test mode gets split into the specified number of parts,
plus property and remote tests, 2 gives 8 parts, and 3 gives 11 parts.
Load went to maybe 18, so there was probably contention slowing things
down.
So probably it needs to start N workers with some parts, and when a
worker finishes, run it with the next part, until all parts are
processed.

Note the very weird workaround for what appears to be some kind of tasty
bug, which causes a segfault. This is not new to this modification,
I was seeing a segfault before at least intermittently when limiting
git-annex test -p to only run a single test group.
Also, the path from one test repo to a remote test repo used to be
"../../foo", which somehow broke when moving the test repos from .t to
.t/N. I don't actually quite understand how it used to work, but
"../foo" seems correct and works in the new situation.
Test output from the concurrent processes is not yet serialized.
Should be easy to do using concurrent-output.
More test groups will probably make the speedup larger. It would
probably be best to have a larger number of test groups and divvy them
amoung subprocesses numbered based on the number of CPU cores, perhaps
times 2 or 3.

After ce91f10132, unannex on a non-annexed
file is expected to fail, unless annex.skipunknown were globally
overridden to true. So this test that used to succeed should probably
fail, but it seems better to just remove it than expect it to fail.
When annex.freezecontent-command is set, and the filesystem does not
support removing write bits, avoid treating it as a crippled filesystem.
The hook may be enough to prevent writing on its own, and some filesystems
ignore attempts to remove write bits.

The new "ort" resolver uses different filenames than what the test suite
accepted when resolving a conflict between a directory an an annexed
file. Make the test looser in what it accepts, so it will work with old
and new git.
Other tests still look for "conflictor.variant" as a prefix,
because when eg resolving a conflicted merge of 2 annexed files,
the filename is not changed by the ort resolver, and I didn't want to
unncessarily loosen the test.
Also I'm not entirely happy with the filenames used by the ort resolver,
see comment.
There's still another test failure caused by that resolver that is not
fixed yet.
Caused by dirContains ".." "foo" being incorrectly False.
Also added a test of dirContains, which includes all the previous bug fixes
I could find and some obvious cases.

test: Put gpg temp home directory in system temp directory, not filesystem
being tested.
Since I've found indications gpg can fail talking to the agent when the
socket ends up on eg, fat. And to hopefully fix this bug report I've
followed up on.
The main risk in using the system temp dir is that TMPDIR could be set to a
long directory path, which is too long to put a unix socket in. To
partially amelorate that risk, it uses either an absolute or a relative
path, whichever is shorter. (Hopefully gpg will not convert it to a longer
form of the path..)
If the user sets TMPDIR to something so long a path to it +
"S.gpg-agent" is too long, I suppose that's their issue to deal with.

This is a bit surprising, it seems that chmod -R -w on windows actually
had some effect. But also, on Windows lockContentShared
has to write to a lock file, so it cannot work in a readonly repo.
So git-annex cannot support readonly repos on Windows.

Freeze first sets the file perms, and then runs
freezecontent-command. Thaw runs thawcontent-command before
restoring file permissions. This is in case the freeze command
prevents changing file perms, as eg setting a file immutable does.
Also, changing file perms tends to mess up previously set ACLs.
git-annex init's probe for crippled filesystem uses them, so if file perms
don't work, but freezecontent-command manages to prevent write to a file,
it won't treat the filesystem as crippled.
When the the filesystem has been probed as crippled, the hooks are not
used, because there seems to be no point then; git-annex won't be relying
on locking annex objects down. Also, this avoids them being run when the
file perms have not been changed, in case they somehow rely on
git-annex's setting of the file perms in order to work.

When two files have the same content, and a required content expression
matches one but not the other, dropping the latter file will fail as it
would also remove the content of the required file.
This will slow down drop (w/o --auto), dropunused, mirror, and move, by one
keys db lookup per file. But I did include an optimisation to avoid a
double db lookup in the drop --auto / sync --content case. I suspect that
dropunused could also use PreferredContentChecked True, but haven't
entirely thought it through and it's rarely used with enough files for the
optimisation to matter.

Make sure that tip keeps working.
I tried to go futher and touch the file and make sure it stayed what it
was converted to, but struggled with some weird and not entirely
reproducable behavior, so kept the tests simple for now.
Not yet used, but allows getting the size of items in the tree fairly
cheaply.
I noticed that CmdLine.Seek uses ls-tree and the feeds the files into
another long-running process to check their size. That would be an
example of a place that might be sped up by using this. Although in that
particular case, it only needs to know the size of unlocked files, not
locked. And since enabling --long probably doubles the ls-tree runtime
or more, the overhead of using it there may outwweigh the benefit.
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.

The test suite contains its own tests that test a lot of basic stuff
about git remotes, mostly in passing to set up other situations.
But testremote does try some unusual edge cases, which may as
well be tried for git remotes as well as directory, especially since
it's so little code to add it.
