Fixes updating git index file after getting an unlocked file when
annex.stalldetection is set.
The transferrer may want to send additional protocol messages when it's
shut down. Closing the read handle prevented it from doing that, and caused
it to crash rather than cleanly shutting down.
Draining the handle without processing the protocol seemed ok to do,
because anything it outputs is going to be some side message displayed
at shutdown. Displaying those once per transferrer process that is running
seems unncessary.

When concurrency is enabled, there can be worker threads still running
when the time limit is checked. Exiting right there does not
give those threads time to finish what they're doing. Instead, the seeking
is wrapped up, and git-annex then shuts down cleanly.
The whole point of --time-limit existing, rather than using timeout(1)
when running git-annex is to let git-annex finish the action(s) it is
working on when the time limit is reached, and shut down cleanly.
I noticed this problem when investigating why restagePointerFile might
not have run after get/drop of an unlocked file. With --time-limit -J,
a worker thread may have finished updating a work tree file, and be killed
by the time limit check before it can run restagePointerFile. So despite
--time-limit running the shutdown actions, the work tree file didn't get
restaged.

It's hard to know what's a good default for this. But 1 mb seems way too
small, because it's very easy for a git pull or some similar operation
that we don't think of as using much space to use up 1 mb of space.
Most people would want to free up some space if a filesystem only had 100
mb free. But on a small VPS, it's probably not uncommon to have only 1 gb
free. So 1 gb is too large for annex.diskreserve.
While old 1 gb USB keys are around, it's unlikely that anyone is
relying on them to shuttle annex data around; it would be worth anyone's
time to upgrade to a 32 gb or larger cheap modern USB key ($5).

Fix a reversion that prevented git-annex from working in a repository when
--git-dir or GIT_DIR is specified to relocate the git directory to
somewhere else. (Introduced in version 10.20220525)
checkRepoConfigInaccessible could still run git config --list, just passing
--git-dir. It seems not necessary, because I know that passing --git-dir
bypasses git's check for repo ownership. I suppose it might be that git
eventually changes to check something about the ownership of the working
tree, so passing --git-dir without --work-tree would still be worth doing.
But for now this is the simple fix.

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.

I looked at all man pages with --all, and this was the only one that
needs to add this disclaimer. Others like get and drop obviously
won't operate on dead keys anyway, because a dead key does not have any
content located anywhere.
Fix a reversion that made dead keys not be skipped when operating on all
keys via --all or in a bare repo. (Introduced in version 8.20200720)
Also, improved the documentation of git-annex-dead, it does not only apply
to fsck --all.
Also, made git-annex fsck, when run on a file whose key is dead, display
that. Before, it displayed that only when run with --all, but with this
fix, it skips dead keys with --all. But it can still be run on a file that
uses a dead key, and displaying "This key is dead" explains to the user
why it does not consider missing content for it to be a problem.

Use curl for downloads from git remotes when annex.url-options and other
git configs are set.
If the url needs a password, curl will fail, and git credential will not be
used to prompt for it. But the user can set --netrc in url-options and
put the password in the netrc file.
This also means that url-options settings like -4 will take effect.
That was the case before commit 1883f7ef8f
forced conduit to be used.
autoEnableSpecialRemotes runs a subprocess, and if the uuid for a git
remote has not been probed yet, that will do a http get that will prompt
for a password. And then the parent process will subsequently prompt
for a password when getting annexed files from the remote.
So the solution is for autoEnableSpecialRemotes to run remoteList before
the subprocess, which will probe for the uuid for the git remote in the
same process that will later be used to get annexed files.
But, Remote.Git imports Annex.Init, and Remote.List imports Remote.Git,
so Annex.Init cannot import Remote.List. Had to pass remoteList into
functions in Annex.Init to get around this dependency loop.
When accessing a git remote over http needs a git credential prompt for a
password, cache it for the lifetime of the git-annex process, rather than
repeatedly prompting.
The git-lfs special remote already caches the credential when discovering
the endpoint. And presumably commands like git pull do as well, since they
may download multiple urls from a remote.
The TMVar CredentialCache is read, so two concurrent calls to
getBasicAuthFromCredential will both prompt for a credential.
There would already be two concurrent password prompts in such a case,
and existing uses of `prompt` probably avoid it. Anyway, it's no worse
than before.
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.
