If .git/config symlinks are ever a thing, this will handle them better.
But mostly, this is to avoid git-repair needing to include CopyFile,
which would complicate it unduely.
In commit dfc4e641b5 git repair was changed
to use remote name, not url, when fetching. But it fetches into a temporary
git repo, which doesn't have remotes configured. Oops.
(In my defense, that commit was made just as covid lockdown started. But
testing? Urk.)

Fixed bug that interrupting git-annex repair (or assistant) while it was
fixing repository corruption would lose objects that were contained in pack
files.
Unpack all pack files and move objects into place *before* deleting the
pack files. The old approach moved the pack files to a temp directory
before unpacking them, which was not interruption safe.

Forces eg, download with youtube-dl without falling back to raw download.
Since youtube-dl failing due to an url not being supported is difficult to
distinguish from it failing due to being blocked in some way, this can be
useful to avoid the fallback of git-annex downloading the raw web page and
adding that.
Since --raw also prevents using special remotes, --no-raw also
allows special remote downloads. Although it's always possible that some
special remote may claim an url and fall back to raw download of the
content, which --no-raw cannot prevent.

Dropping an object with drop --unused or dropunused will mark it as
dead, preventing fsck --all from complaining about it after it's been
dropped from all repositories.
If another repository still has a copy, it won't be treated as dead
until it's also dropped from there.
The drop has to use --unused, can't be --key or something else, because
this indicates that the user has recently ran git-annex unused. If it
checked the unused log on every drop, bad things would happen when the
unused log was out of date, eg a file used to be unused but then got
re-added. Marking such a file as dead could be confusing. When the user
uses --unused/dropunused, they must consider the unused information to be
up-to-date.
The particular workflow this enables is:
git annex add foo
git annex unannex foo
git annex unused
git annex drop --unused / dropunused
git annex fsck --all # no warnings
The docs for git-annex unannex say to use git-annex unused and dropunused,
so the user should be pointed in this direction when they want to undo an
accidental add.

Transfers from or to a local git repo could fail without a reason being
given, if the content failed to verify, or if the object file's stat
changed while it was being copied. Now display messages in these cases.

When stall detection is enabled, and a transfer is in progress,
it would display a doubled message:
(transfer already in progress, or unable to take transfer lock) (transfer already in progress, or unable to take transfer lock)
That happened because the forward retry decider had a start size of 0,
and an end size of whatever amount of the object the other process had
downloaded. So it incorrectly thought that the transferrer process had
made progress, when it had in fact immediately given up with that
message.
Instead, use the reported value from the progress meter. If a remote
does not report progress, this will mean it doesn't forward retry, in a
situation where it used to. But most remotes do report progress, and any
remote that does not can be fixed to, by using watchFileSize when
downloading. Also, some remotes might preallocate the temp file (eg
bittorrent), so relying on statting its size at this level to get
progress is dubious.
The same change was made to Annex/Transfer.hs, although only
Annex/TransferrerPool.hs needed to be changed to avoid the duplicate
message.
(An alternate fix would have been to start the retry decider with the
size of the object file before downloading begins, rather than 0.)

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.
