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.

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.

Remove closed bugs and todos that were last edited or commented before 2020.
Except for ones tagged projects/* since projects like datalad want to keep
around records of old deleted bugs longer.

This was an old problem when the files were being added unlocked,
so the changelog mentions that being fixed. However, recently it's also
affected locked files.
The fix for locked files is kind of stupidly simple. moveAnnex already
handles populating unlocked files, and only does it when the object file
was not already present. So remove the redundant populateUnlockedFiles
call. (That call was added all the way back in
cfaac52b88, and has always been
unncessary.)

moveAnnex only gets to that check if the object file was not present
before. So in the case where dup files are being added repeatedly,
it will only run the first time, and so there's no significant speedup
from doing it; all it avoids is a single sqlite lookup. Since MVar
accesses do have overhead, it's better to optimise for the common case,
where unlocked files are supported.
removeAnnex is less clear cut, but I think mostly is skipped running on
keys when the object has already been dropped, so similar reasoning
applies.
This will mostly just avoid a DB lookup, so things get marginally
faster. But in cases where there are many files using the same key, it
can be a more significant speedup.
Added overhead is one MVar lookup per call, which should be small
enough, since this happens after transferring or ingesting a file,
which is always a lot more work than that. It would be nice, though,
to move getGitConfig to AnnexRead, which there is an open todo about.
reconcileStaged was doing a redundant scan to scannAnnexedFiles.
It would probably make sense to move the body of scannAnnexedFiles
into reconcileStaged, the separation does not really serve any purpose.

This is quite a subtle edge case, see the bug report for full details.
The second git diff is needed only when there's a merge conflict.
It would be possible to speed it up marginally by using
--diff-filter=Unmerged, but probably not enough to bother with.

It makes sense to keep the key used by the old version of an
associated file, until the merge conflict is resolved.
Note that, since in this case git diff is being run with --index, it's
not possible to use -1 or -3, which would let the keys
associated with the new versions of the file also be added. That would
be better, because it's possible that the local modification to the file
that caused the merge conflict has not yet gotten its new key recorded
in the db.
Opened a bug about a case this is thus not able to address.

* drop: When two files have the same content, and a preferred content
expression matches one but not the other, do not drop the file.
* sync --content, assistant: Fix an edge case where a file that is not
preferred content did not get dropped.
The sync --content edge case is that handleDropsFrom loaded associated files
and used them without verifying that the information from the database was
not stale.
It seemed best to avoid changing --want-drop's behavior, this way when
debugging a preferred content expression with it, the files matched will
still reflect the expression. So added a note to the --want-drop documentation,
to make clear it may not behave identically to git-annex drop --auto.
While it would be possible to introspect the preferred content
expression to see if it matches on filenames, and only look up the
associated files when it does, it's generally fairly rare for 2 files to
have the same content, and the database lookup is already avoided when
there's only 1 file, so I did not implement that further optimisation.
Note that there are still some situations where the associated files
database does not get locked files recorded in it, which will prevent
this fix from working.
