giveup changed to filter out control characters. (It is too low level to
make it use StringContainingQuotedPath.)
error still does not, but it should only be used for internal errors,
where the message is not attacker-controlled.
Changed a lot of existing error to giveup when it is not strictly an
internal error.
Of course, other exceptions can still be thrown, either by code in
git-annex, or a library, that include some attacker-controlled value.
This does not guard against those.

path to a bare repo when git config is not allowed to list the configs
due to the CVE-2022-24765 fix.
That resulted in a confusing error message, and prevented the nice
message that explains how to mark the repo as safe to use.
Made isBare a tristate so that the case where core.bare is not returned can
be handled.
The handling in updateLocation is to check if the directory
contains config and objects and if so assume it's bare.
Note that if that heuristic is somehow wrong, it would construct a repo
that thinks it's bare but is not. That could cause follow-on problems,
but since git-annex then checks checkRepoConfigInaccessible, and skips
using the repo anyway, a wrong guess should not be a problem.

init: Avoid scanning for annexed files, which can be lengthy in a
large repository. Instead that scan is done on demand. This lets git-annex
init be run and some query commands be used in a repository without
waiting.
Note that autoinit already behaved this way, so while this will mean some
commands like git-annex get/unlock/add will do the scan the first time run,
that is not really a significant behavior change.
And, it's really better to have a consistent behavior. The reason for
the inconsistency was a strange bug discussed in
b3c4579c79. Avoiding reconcileStaged in
init will keep avoiding whatever that was.

The flush was only done Annex.run' to make sure that the queue was flushed
before git-annex exits. But, doing it there means that as soon as one
change gets queued, it gets flushed soon after, which contributes to
excessive writes to the database, slowing git-annex down.
(This does not yet speed git-annex up, but it is a stepping stone to
doing so.)
Database queues do not autoflush when garbage collected, so have to
be flushed explicitly. I don't think it's possible to make them
autoflush (except perhaps if git-annex sqitched to using ResourceT..).
The comment in Database.Keys.closeDb used to be accurate, since the
automatic flushing did mean that all writes reached the database even
when closeDb was not called. But now, closeDb or flushDb needs to be
called before stopping using an Annex state. So, removed that comment.
In Remote.Git, change to using quiesce everywhere that it used to use
stopCoProcesses. This means that uses on onLocal in there are just as
slow as before. I considered only calling closeDb on the local git remotes
when git-annex exits. But, the reason that Remote.Git calls stopCoProcesses
in each onLocal is so as not to leave git processes running that have files
open on the remote repo, when it's on removable media. So, it seemed to make
sense to also closeDb after each one, since sqlite may also keep files
open. Although that has not seemed to cause problems with removable
media so far. It was also just easier to quiesce in each onLocal than
once at the end. This does likely leave performance on the floor, so
could be revisited.
In Annex.Content.saveState, there was no reason to close the db,
flushing it is enough.
The rest of the changes are from auditing for Annex.new, and making
sure that quiesce is called, after any action that might possibly need
it.
After that audit, I'm pretty sure that the change to Annex.run' is
safe. The only concern might be that this does let more changes get
queued for write to the db, and if git-annex is interrupted, those will be
lost. But interrupting git-annex can obviously already prevent it from
writing the most recent change to the db, so it must recover from such
lost data... right?

git-annex get when run as the first git-annex command in a new repo did not
populate unlocked files. (Reversion in version 8.20210621)
I am not entirely happy with this, because I don't understand how
428c91606b caused the problem in the first
place, and I don't fully understand how skipping calling scanAnnexedFiles
during autoinit avoids the problem.
Kept the explicit call to scanAnnexedFiles during git-annex init,
so that when reconcileStaged is expensive, it can be made to run then,
rather than at some later point when the information is needed.

* sync: When --quiet is used, run git commit, push, and pull without
their ususual output.
* merge: When --quiet is used, run git merge without its usual output.
This might also make --quiet work better for some other commands
that make commits, like git-annex adjust.

Rather than direct mode, which this is a small step on the path to
removing.
Init on a crippled filesystem already used v7 adjusted branches,
and like that, this doesn't pose any interoperability issues with old
versions of git-annex that clone the same repo, because files are only
unlocked on the adjusted branch.
