Use separate stages for download and upload. In the common case where
it downloads the file from one remote and then uploads to the other,
those are by far the most expensive operations, and there's a decent
chance the two remotes bottleneck on different resources.
Suppose it's being run with -J2 and a bunch of 10 mb files. Two threads
will be started both downloading from the src remote. They will probably
finish at the same time. Then two threads will be started uploading to
the dst remote. They will probably take the same time as well. Before
this change, it would alternate back and forth, bottlenecking on src and dst.
With this change, as soon as the two threads start uploading to dst, two
more threads are able to start, downloading from src. So bandwidth to
both remotes is saturated more often.
Other commands that use transferStages only send in one direction at a
time. So the worker threads for the other direction will sit idle, and
there will be no change in their behavior.

Lock the local content for drop after getting it from src, to prevent another
process from using the local content as a copy and dropping it from src,
which would prevent dropping the local content after sending it to dest.
Support resuming an interrupted move that downloaded the content from
src, leaving the local content populated. In this case, the location log
has not been updated to say the content is present locally, so we can
assume that it's resuming and go ahead and drop the local content after
sending it to dest.
Note that if a `git-annex get` is being ran at the same time as a
`git-annex move --from --to`, it may get a file just before the move
processes it. So the location log has not been updated yet, and the move
thinks it's resuming. Resulting in local copy being dropped after it's
sent to the dest. This race is something we'll just have to live with,
it seems.
I also gave up on the idea of checking if the location log had been updated
by a `git-annex get` that is ran at the same time. That wouldn't work, because
the location log is precached in the seek stage, so reading it again after
sending the content to dest would not notice changes made to it, unless the cache
were invalidated, which would slow it down a lot. That idea anyway was subject
to races where it would not detect the concurrent `git-annex get`.
So concurrent `git-annex get` will have results that may be surprising.
To make that less surprising, updated the documentation of this feature to
be explicit that it downloads content to the local repository
temporarily.

Allowing --from and --to as an alternative to --from or --to
is hard to do with optparse-applicative!
The obvious approach of (pfrom <|> pto <|> pfromandto) does not work
when pfromandto uses the same option names as pfrom and pto do.
It compiles but the generated parser does not work for all desired
combinations.
Instead, have to parse optionally from and optionally to. When neither
is provided, the parser succeeds, but it's a result that can't be
handled. So, have to giveup after option parsing. There does not seem to
be a way to make an optparse-applicative Parser give up internally
either.
Also, need seek' because I first tried making fto be a where binding,
but that resulted in a hang when git-annex move was run without --from
or --to. I think because startConcurrency was not expecting the stages
value to contain an exception and so ended up blocking.

I've long been asked for `git-annex find --all` or something like that,
but pushed back on it because I feel that the command is analagous to
find(1) and so it would be surprising for it to list keys rather than
files. So instead, add a new findkeys subcommand.
Note that the use of withKeyOptions is rather strange because usually
that is used to fall back to --all rather than listing files, but here
it's made to default to --all like behavior and never list files.
A performance thing that could be improved is that withKeyOptions
always reads and caches location logs. But findkeys with no options does
not need them, so it could be made faster. That caching does speed up
options like --in though. This is really just a subset of a more general
performance thing that --all reads location logs sometimes unncessarily.
Anyway, it needs to read the location log in order to checkDead,
and it seems good that findkeys does skip dead keys.
Also, cleaned up comments on git-annex-find man page asking for --all
option.

Note that when this is specified and an older git-annex is used to
enableremote such a special remote, it will simply ignore the cost= field
and use whatever the default cost is.
In passing, fixed adb to support the remote.name.cost and
remote.name.cost-command configs.

When a web special remote does not have urlinclude/urlexclude
configured, make it respect the configuration of other web special
remotes and avoid using urls that match the config of another.
Note that the other web special remote does not have to be enabled.
That seems ok, it would have been extra work to check for only ones that
are enabled.
The implementation does mean that the web special remote re-parses
its own config once at startup, as well as re-parsing the configs of any
other web special remotes. This should be a very small slowdown
unless there are lots of web special remotes.

Allow initremote of additional special remotes with type=web, in addition
to the default web special remote.
When --sameas=web is used, these provide additional names for the web
special remote, and may also have their own additional configuration
(once there is any for the web special remote) and cost.

Remove closed bugs and todos that were last edited or commented before 2022.
Except for ones tagged projects/* since projects like datalad want to keep
around records of old deleted bugs longer.
Command line used:
for f in $(grep -l '|done\]\]' -- ./*.mdwn); do if ! grep -q "projects/" "$f"; then d="$(echo "$f" | sed 's/.mdwn$//')"; if [ -z "$(git log --since=01-01-2022 --pretty=oneline -- "$f")" -a -z "$(git log --since=01-01-2022 --pretty=oneline -- "$d")" ]; then git rm -- "./$f" ; git rm -rf "./$d"; fi; fi; done
for f in $(grep -l '\[\[done\]\]' -- ./*.mdwn); do if ! grep -q "projects/" "$f"; then d="$(echo "$f" | sed 's/.mdwn$//')"; if [ -z "$(git log --since=01-01-2022 --pretty=oneline -- "$f")" -a -z "$(git log --since=01-01-2022 --pretty=oneline -- "$d")" ]; then git rm -- "./$f" ; git rm -rf "./$d"; fi; fi; done
The moved bugs that link to [[done]] were not matching because it wanted
that to link to bugs/done, but it was a broken link after rename. Adding
a stub datalad/done page to avoid the broken link, and adjusting the
pagespec so those are listed.
This is to cut down on the number of files in bugs/, which makes it slow
to file new bug reports or update active bug reports. These old bugs
were about 1/3rd of the files in there. These projects want lists of
their old bugs to still be accessible, and have the lists on their
project pages, which will still list the old bugs.
Commands used:
for f in $(git grep -l '\[\[!tag projects/dandi\]\]'); do if grep -q 'done\]\]' "$f"; then git mv "$f" ../projects/dandi/bugs-done; g=$(echo "$f" | sed 's/.mdwn//'); if [ -d "$g" ]; then git mv "$g" ../projects/dandi/bugs-done; fi; fi; done
for f in $(git grep -l '\[\[!tag projects/repronim\]\]'); do if grep -q 'done\]\]' "$f"; then git mv "$f" ../projects/repronim/bugs-done; g=$(echo "$f" | sed 's/.mdwn//'); if [ -d "$g" ]; then git mv "$g" ../projects/repronim/bugs-done; fi; fi; done
for f in $(git grep -l '\[\[!tag projects/datalad\]\]'); do if grep -q 'done\]\]' "$f"; then git mv "$f" ../projects/datalad/bugs-done; g=$(echo "$f" | sed 's/.mdwn//'); if [ -d "$g" ]; then git mv "$g" ../projects/datalad/bugs-done; fi; fi; done
That assumes that bugs are not tagged by multiple projects at the same
time. Of the ones I moved, I've checked and none are.
Could do the same with todo/ but there are only 370 files in there, and
less than 84 of them could be moved this way, which does not seem likely
to produce a sizeable speedup.

readish ignores a trailing string after a number, but to support values
like "YYYY:MM:DD" which it makes sense to compare lexographically,
require the whole string to be parsed as a number in order to enable
numeric comparison.

Speed up git-annex upgrade (from v5) and init in a repository that has
submodules. Setting the config does not affect the submodules, so avoid
the work of getting status in them, which may involve using the smudge
filter etc.

Added --anything (and --nothing). Eg, git-annex find --anything will list
all annexed files whether or not the content is present. This is slightly
faster and clearer than --include=* or --exclude=*
While I can't imagine how --nothing will be used, preferred content
expressions already had anything and nothing, so might as well support both
as matching options as well.

Improve handling of some .git/annex/ subdirectories being on other
filesystems, in the bittorrent special remote, and youtube-dl integration,
and git-annex addurl.
The only one of these that I've confirmed to be a problem is in the
bittorrent special remote when .git/annex/tmp and .git/annex/othertmp are
on different filesystems.
As well as auditing for renameFile, also audited for createLink, all of
those are ok as are the other remaining renameFile calls. Also audited all
code paths that use .git/annex/othertmp, and did not find any other
cross-device problems. So, removing mention of othertmp needing to be on
the same device.
