This fixes a problem with datalad's test suite, where loading the cluster
log happened to cause the git-annex branch commits to take a different
shape, with an additional commit.
It's also faster though, since many commands don't need the cluster log.
Just fill Annex.clusters with a thunk.

This was caused by commit fb8ab2469d putting
an isPointerFile check in the wrong place. So if the file was not a pointer
file at that point, but got replaced by one before the file got locked
down, the pointer file would be ingested into the annex.
The fix is simply to move the isPointerFile check to after safeToAdd locks
down the file. Now if the file changes to a pointer file after the
isPointerFile check, ingestion will see that it changed after lockdown,
and will refuse to add it to the annex.

They could be missing due to an interrupted git-annex at just the wrong
time during a prior graft, after which the tree objects got garbage
collected.
Or they could be missing because of manual messing with the git-annex
branch, eg resetting it to back before the graft commit.

Fix a bug where interrupting git-annex while it is updating the git-annex
branch could lead to git fsck complaining about missing tree objects.
Interrupting git-annex while regraftexports is running in a transition
that is forgetting git-annex branch history would leave the
repository with a git-annex branch that did not contain the tree shas
listed in export.log. That lets those trees be garbage collected.
A subsequent run of the same transition then regrafts the trees listed
in export.log into the git-annex branch. But those trees have been lost.
Note that both sides of `if neednewlocalbranch` are atomic now. I had
thought only the True side needed to be, but I do think there may be
cases where the False side needs to be as well.

When building an adjusted unlocked branch, make pointer files executable
when the annex object file is executable.
This slows down git-annex adjust --unlock/--unlock-present by needing to
stat all annex object files in the tree. Probably not a significant
slowdown compared to other work they do, but I have not benchmarked.
I chose to leave git-annex adjust --unlock marked as stable, even though
get or drop of an object file can change whether it would make the pointer
file executable. Partly because making it unstable would slow down
re-adjustment, and partly for symmetry with the handling of an unlocked
pointer file that is executable when the content is dropped, which does not
remove its execute bit.
While redundant concurrent transfers were already prevented in most
cases, it failed to prevent the case where two different repositories were
sending the same content to the same repository. By removing the uuid
from the transfer lock file for Download transfers, one repository
sending content will block the other one from also sending the same
content.
In order to interoperate with old git-annex, the old lock file is still
locked, as well as locking the new one. That added a lot of extra code
and work, and the plan is to eventually stop locking the old lock file,
at some point in time when an old git-annex process is unlikely to be
running at the same time.
Note that in the case of 2 repositories both doing eg
`git-annex copy foo --to origin`
the output is not that great:
copy b (to origin...)
transfer already in progress, or unable to take transfer lock
git-annex: transfer already in progress, or unable to take transfer lock
97% 966.81 MiB 534 GiB/s 0sp2pstdio: 1 failed
Lost connection (fd:14: hPutBuf: resource vanished (Broken pipe))
Transfer failed
Perhaps that output could be cleaned up? Anyway, it's a lot better than letting
the redundant transfer happen and then failing with an obscure error about
a temp file, which is what it did before. And it seems users don't often
try to do this, since nobody ever reported this bug to me before.
(The "97%" there is actually how far along the *other* transfer is.)

The getSocket comment that mentioned using ":port"
in the hostname seems to have been incorrect or be out of date.
After all, the bug report came when the user first tried doing that,
and it didn't work.

external: Monitor file size when getting content from external special
remotes and use that to update the progress meter, in case the external
special remote program does not report progress.
This relies on 703a70cafa to prevent ever

Improve annex.stalldetection to handle remotes that update progress less
frequently than the configured time period.
In particular, this makes remotes that don't report progress but are
chunked work when transferring a single chunk takes longer than the
specified time period.
Any remotes that just have very low update granulatity would also be
handled by this.
The change to Remote.Helper.Chunked avoids an extra progress update when
resuming an interrupted upload. In that case, the code saw first Nothing
and then Just the already transferred number of bytes, which defeated this
new heuristic. This change will mean that, when resuming an interrupted
upload to a chunked remote that does not do its own progress reporting, the
progress display does not start out displaying the amount sent so far,
until after the first chunk is sent. This behavior change does not seem
like a major problem.
About the scalefudgefactor, it seems reasonable to expect subsequent chunks
to take no more than 1.5 times as long as the first chunk to transfer.
Could set it to 1, but then any chunk taking a little longer would be
treated as a stall. 2 also seems a likely value. Even 10 might be fine?
