In Makefile, listed additional deps of Build/Standalone. Without that,
it does not get updated for the change to Utility/LinuxMkLibs.hs when
compiling incrementally.

Fix a hang that occasionally occurred during commands such as move.
(A bug introduced in 10.20220927, in
commit 6a3bd283b8)
The restage.log was kept locked while running a complex index refresh
action. In an unusual situation, that action could need to write to the
restage log, which caused a deadlock.
The solution is a two-stage process. First the restage.log is moved to a
work file, which is done with the lock held. Then the content of the work
file is read and processed, which happens without the lock being held.
This is all done in a crash-safe manner.
Note that streamRestageLog may not be fully safe to run concurrently
with itself. That's ok, because restagePointerFiles uses it with the
index lock held, so only one can be run at a time.
streamRestageLog does delete the restage.old file at the end without
locking. If a calcRestageLog is run concurrently, it will either see the
file content before it was deleted, or will see it's missing. Either is
ok, because at most this will cause calcRestageLog to report more
work remains to be done than there is.

The splitting of the tests into parts for parallelism made --pattern
do extra work, because init tests have to be run for each part, but
many of the parts are empty.
For example, git-annex test --pattern '/move (ssh remote)/'
took 12 seconds to run before. This improves the runtime to 4 seconds.

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.

Increasing the size of the queue 10x makes git-annex init 7% faster in a
repository with 86000 annexed files.
The memory use goes up, from 70876 kb to 85376 kb.
