avoid interleaving command stages with Concurrency 1
Before, -J1 was different than no -J: It makes concurrent-output be used
for display, and it actually can run concurrent jobs in some situations.
Eg, a perform stage and a cleanup stage can both run.
dupState is used in several places, and changes NonConcurrent to
Concurrent 1. My concern is that this might, in some case, enable
that concurrent behavior. And in particular, that it might get enabled in
--batch mode, when the user is not expecting concurrent output because
they did not pass -J.
While I don't have a test case where that happens and causes out of
order output, it looks like it could, and so prudent to make this change.
--batch combined with -J now runs batch requests concurrently for many
commands. Before, the combination was accepted, but did not enable
concurrency. Since the output of batch requests can be in any order, --json
with the new "input" field is recommended to be used, to determine which
batch request each response corresponds to.
If --json is not used, batch mode still runs concurrently, using the usual
concurrent-output. That will not be very useful for most batch mode users,
probably, but who knows.
If a program was using --batch -J before, and was parsing non-json output,
this could break it. But, it was relying on git-annex not supporting
concurrency despite it being enabled, so it should have expected concurrent
output. So, I think that's ok.
annex.jobs does not enable concurrency in --batch mode, because that would
confuse programs that use --batch but don't expect concurrency.
This is prep for making batchCommandAction use commandAction,
which will enable concurrency for batch mode. Since commandAction can't
return anything, have to handle the case of a CommandStart that chooses
to do nothing in a different way.
The use case of this field is mostly to support -J combined with --json.
When that is implemented, a user will be able to look at the field to
determine which of the requests they have sent it corresponds to.
The field typically has a single value in its list, but in some cases
mutliple values (eg 2 command-line params) are combined together and the
list will have more.
Note that json parsing was already non-strict, so old git-annex metadata
--json --batch can be fed json produced by the new git-annex and will
not stumble over the new field.
No behavior changes (hopefully), just adding SeekInput and plumbing it
through to the JSON display code for later use.
Over the course of 2 grueling days.
withFilesNotInGit reimplemented in terms of seekHelper
should be the only possible behavior change. It seems to test as
behaving the same.
Note that seekHelper dummies up the SeekInput in the case where
segmentPaths' gives up on sorting the expanded paths because there are
too many input paths. When SeekInput later gets exposed as a json field,
that will result in it being a little bit wrong in the case where
100 or more paths are passed to a git-annex command. I think this is a
subtle enough problem to not matter. If it does turn out to be a
problem, fixing it would require splitting up the input
parameters into groups of < 100, which would make git ls-files run
perhaps more than is necessary. May want to revisit this, because that
fix seems fairly low-impact.
Potentially fixes https://git-annex.branchable.com/bugs/concurrent_git-annex-copy_to_s3_special_remote_fails/
although I don't know if it does.
My thinking is, ResourceT may allocate a resource and then free it,
and a unforced thunk to that resource could result in reading memory
that has since been overwritten by something else, or in a SEGV,
depending. While that seems kind of like a bug in ResourceT to me, if it
is what's happening, this will avoid it. If it's not, this doesn't
really hurt much since the values are all smallish.

IIRC these build flags were added because the dep chains were a bit too
long, or perhaps because the libraries were not available in Debian stable,
or something like that. That was long ago, those reasons no longer apply,
and users get confused when builtin special remotes are not available, so
it seems best to remove the build flags now.
If this does cause a problem it can be reverted of course..

resolvemerge: Improve cleanup of files that were deleted by one side of a conflicted merge, and modified by the other side
This case was handled by cleanConflictCruft, but only when the annexed
file's object was present. When not present, it left the annexed file
with the original name, not checked into git, while adding the variant
file. So, add an explicit deletion of the deleted file in this case.
My specific case where this happened actually involves
merge.directoryRenames=conflict. After a merge involving that,
the situation was the file appears as "added by them", because that
caused the file that they added to be moved into a directory we renamed.
That case is the same as them adding a modified version of the file,
while we deleted it. (Except for the history of the file, since it's a
new file, but this doesn't look at history.)

make automerge behavior when one side deleted explict
This does not actually change how the merge conflict is resolved when
one side deleted the file, but it was not documented before, and I think
it only worked by accident.

One reason is, 5 is an arbitrary number so ought to be configurable.
The real reason though, is I wanted to make the man page explain when
forward retry can override annex.retry, and having a config made the
man page easier to write.
This fixes the problem that, if forwardRetry was checked for the first 5
and decided to retry, the 6th would go to configuredRetry which would
see the counter was 6 and so wait retry-delay*2^5 seconds (default 32).
Now, it waits for retry-delay before each retry, even when forwardRetry
initiated the retry.
That made Utility.FileMode depend on unix, but Utility.Tmp now depends
on it, and is used by Setup, which does not. So it was easiest to remove
this, especially since it's not used.
Fixed several cases where files were created without file mode bits that
the umask would usually set. This included exports to the directory special
remote, torrent files used by the bittorrent special remote, hooks written
by git-annex init, and some log files in .git/annex/
Audited all calls, looking for ones that didn't want the umask bits to be
set. All such turned out to already set the specific restrictive file mode
they wanted.
fix some file modes in calls to withTmpFileIn to honor umask
Also audited for other calls to openTempFile, and all are ok,
except for viaTmp which will need further work.
Remote.Directory fixed to set umask mode when writing to an export,
although it has another one using viaTmp that's not fixed.
Will make exports that are published via a http server running as
another user work, for example.
Remote.BitTorrent fixed to set umask mode when downloading the torrent
file. Normally this does not matter as that file does not hang around
after the download, but if a bittorrent download were started by one user,
got interrupted and then another user ran it, this will let them access
the torrent file created by the first user.
Also tested what happens if the other special remote has importtree=yes
and exporttree=yes, and in that case, download via httpalso works too,
without needing to implement any importtree methods here.
It might be possible to make it automatically set exporttree=yes if the
--sameas does. Didn't try, will probably be layering issues.
Or perhaps it should be inherited by sameas like some
other configs? But then, wouldn't it also make sense to inherit
importree=yes? But as shown here, it's not needed by this kind of
remote.
"http" was too generic and easy to confuse with web. The new name makes
clear it's used in addition to some other remote. And other protocols
can use the same naming scheme.
