Clean the standalone environment before running the su command
to run "sh". Otherwise, PATH leaked through, causing it to run
git-annex.linux/bin/sh, but GIT_ANNEX_DIR was not set,
which caused that script to not work:
[2022-10-26 15:07:02.145466106] (Utility.Process) process [938146] call: pkexec ["sh","-c","cd '/home/joey/tmp/git-annex.linux/r' && '/home/joey/tmp/git-annex.linux/git-annex' 'enable-tor' '1000'"]
/home/joey/tmp/git-annex.linux/bin/sh: 4: exec: /exe/sh: not found
Changed programPath to not use GIT_ANNEX_PROGRAMPATH,
but instead run the scripts at the top of GIT_ANNEX_DIR.
That works both when the standalone environment is set up, and when it's
not.

Commit ff0927bde9 broke this, it made it
try to read all of the input before looking for the code. But, wormhole
keeps running until it sends the file, so that caused a deadlock. Oops.

p2p: Pass wormhole the --appid option before the receive/send command, as
it does not accept that option after the command
I'm left wondering, did I get this wrong from the beginning, or did
wormhole change its option parser? I'm reminded of the change in 0.8.2
where it silently changed what FD the pairing code was output to.
But, looking at the wormhole source, it was at least putting --appid before
send in its test suite from the introduction of the option.
So I think probably this has always been broken. On 2021-12-31 the --appid
option was enabled, and it took until now for someone to try
git-annex p2p --pair and notice that flag day broke it..

Improve handling of directory special remotes with importtree=yes whose
ignoreinode setting has been changed. (By either enableremote or by
upgrading to commit 3e2f1f73cbc5fc10475745b3c3133267bd1850a7.)
When getting a file from such a remote, accept the content that would have
been accepted with the previous ignoreinode setting.
After a change to ignoreinode, importing a tree from the remote will
re-import and generate new content identifiers using the new config. So
when ignoreinode has changed to no, the inodes will be learned, and after
that point, a change in an inode will be detected as a change. Before
re-importing, a change in an inode will be ignored, as it was before the
ignoreinode change. This seems acceptble, because the user can re-import
immediately if they urgently need to add inodes. And if not, they'll
do it sometime, presumably, and the change will take effect then.

Fix crash importing from a directory special remote that contains a broken
symlink.
The crash was in listImportableContentsM but some other places in
Remote.Directory also seemed like they could have the same problem.
Also audited for other places that have such a problem. Not all calls
to getFileStatus are bad, in some cases it's better to crash on something
unexpected. For example, `git-annex import path` when the path is a broken
symlink should crash, the same as when it does not exist. Many of the
getFileStatus calls are like that, particularly when they involve
.git/annex/objects which should never have a broken symlink in it.
Fixed a few other possible cases of the problem.

Recent commit got amended accidentially to include this typo. Argh. It
was fine, then I tweakd the commit message and accidentially staged this
breakage.
As outlined in my blog post, I object to Microsoft training their Copilot
model on my code, and believe it likely violates my copyright.
https://joeyh.name/blog/entry/a_bitter_pill_for_Microsoft_Copilot/
While I never push git-annex to Github, other users choose to. And since
Microsoft is now selling access to Copilot to anyone, this situation is
escalating.
Some small wins, almost certianly swamped by the system calls, but still
worthwhile progress on the RawFilePath conversion.

Added support for "megabit" and related bandwidth units in
annex.stalldetection and everywhere else that git-annex parses data units.
Note that the short form is "Mbit" not "Mb" because that differs from "MB"
only in case, and git-annex parses units case-insensitively. It would be
horrible if two different versions of git-annex parsed the same value
differently, so I don't think "Mb" can be supported.
See comment for bonus sad story from my childhood.

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.

In aeson 2.0, Text has been replaced by the Key type and HashMap by the
KeyMap interface. Accomodating this required adding some CPP in order to
still be able to compile with aeson < 2.0. The required changes were:
* Prevent Key from being re-exported by Utilities.Aeson, as it clashes
with git-annex's own Key type.
* Fix up convertion from String/Text to Key (or Text in aeson 1.*) in a
couple of places
* Import Data.Aeson.KeyMap instead of Data.HashMap.Strict, as they are
mostly API-compatible. insertWith needs to be replaced by unionWith,
however, as KeyMap lacks the former function.
This fixes a FD leak when annex.pidlock is set and -J is used. Also, it
fixes bugs where the pid lock file got deleted because one thread was
done with it, while another thread was still holding it open.
The LockPool now has two distinct types of resources,
one is per-LockHandle and is used for file Handles, which get closed
when the associated LockHandle is closed. The other one is per lock
file, and gets closed when no more LockHandles use that lock file,
including other shared locks of the same file.
That latter kind is used for the pid lock file, so it's opened by the
first thread to use a lock, and closed when the last thread closes a lock.
In practice, this means that eg git-annex get of several files opens and
closes the pidlock file a few times per file. While with -J5 it will open
the pidlock file, process a number of files, until all the threads happen to
finish together, at which point the pidlock file gets closed, and then
that repeats. So in either case, another process still gets a chance to
take the pidlock.
registerPostRelease has a rather intricate dance, there are fine-grained
STM locks, a STM lock of the pidfile itself, and the actual pidlock file
on disk that are all resolved in stages by it.

This reverts commit 66b2536ea0.
I misunderstood commit ac56a5c2a0
and caused a FD leak when pid locking is not used.
A LockHandle contains an action that will close the underlying lock
file, and that action is run when it is closed. In the case of a shared
lock, the lock file is opened once for each LockHandle, and only
the one for the LockHandle that is being closed will be closed.
This locking has been missing from the beginning of annex.pidlock.
It used to be possble, when two threads are doing conflicting things,
for both to run at the same time despite using locking. Seems likely
that nothing actually had a problem, but it was possible, and this
eliminates that possible source of failure.

Seem there are several races that happen when 2 threads run PidLock.tryLock
at the same time. One involves checkSaneLock of the side lock file, which may
be deleted by another process that is dropping the lock, causing checkSaneLock
to fail. And even with the deletion disabled, it can still fail, Probably due
to linkToLock failing when a second thread overwrites the lock file.
The same can happen when 2 processes do, but then one process just fails
to take the lock, which is fine. But with 2 threads, some actions where failing
even though the process as a whole had the pid lock held.
Utility.LockPool.PidLock already maintains a STM lock, and since it uses
LockShared, 2 threads can hold the pidlock at the same time, and when
the first thread drops the lock, it will remain held by the second
thread, and so the pid lock file should not get deleted until the last
thread to hold it drops the lock. Which is the right behavior, and why a
LockShared STM lock is used in the first place.
The problem is that each time it takes the STM lock, it then also calls
PidLock.tryLock. So that was getting called repeatedly and concurrently.
Fixed by noticing when the shared lock is already held, and stop calling
PidLock.tryLock again, just use the pid lock that already exists then.
Also, LockFile.PidLock.tryLock was deleting the pid lock when it failed
to take the lock, which was entirely wrong. It should only drop the side
lock.

This fixes a reversion introduced in commit
ac56a5c2a0.
I didn't notice there that it was handling the case of a shared lock
file that was still open elsewhere by not running the close action.
This was especially deadly when annex.pidlock is set, as it caused early
deletion of the pid lock file.

It ought to exist, since linkToLock has just created it. However,
Lustre seems to have a rather probabilisitic view of the contents of a
directory, so catching the error if it somehow does not exist and
running the same code path that would be ran if linkToLock failed
might avoid this fun Lustre failure.
