Improve pid locking code to work on filesystems that don't support hard links.
Probing for hard link support in the pid locking code is redundant since
git-annex init already probes that. But, it didn't seem worth threading
that data through; the pid locking code runs at most once per git-annex
process, and only on unusual filesystems. Optimising a single hard link
and unlink isn't worth it.

Added git template directory to Linux standalone tarball and OSX app bundle.
Git does not provide a switch to find out where this directory is, and
while the git-init man page says it will always be in
/usr/share/git-core/templates, that's not the case on OSX with git
installed from homebrew. So, I used a hack taking the --man-path and
constructing a path from that. Works on both Debian and OSX at least.

import --reinject-duplicates
This is the same as running git annex reinject --known, followed by
git-annex import. The advantage to having it in one command is that it
only has to hash each file once; the two commands have to
hash the imported files a second time.

Make import --deduplicate and --skip-duplicates only hash once, not twice
import: --deduplicate and --skip-duplicates were implemented inneficiently;
they unncessarily hashed each file twice. They have been improved to only
hash once.
The new approach is to lock down (minimally) and hash files, and then
reuse that information when importing them.
This was rather tricky, especially in detecting changes to files while
they are being imported.
The output of import changed slightly. While before it silently skipped
over files with eg --skip-duplicates, now it shows each file as it starts
to act on it. Since every file is hashed first thing, it would otherwise
not be clear what file import is chewing on. (Actually, it wasn't clear
before when any of the duplicates switches were used.)

import: Changed how --deduplicate, --skip-duplicates, and --clean-duplicates determine if a file is a duplicate
Before, only content known to be present somewhere was considered a
duplicate. Now, any content that has been annexed before will be considered
a duplicate, even if all annexed copies of the data have been lost.
Note that --clean-duplicates and --deduplicate still check numcopies,
so won't delete duplicate files unless there's an annexed copy.
This makes import use the same method as reinject --known.
The man page already said that duplicate meant "its content is either
present in the local repository already, or git-annex knows of another
repository that contains it, or it was present in the annex before but has
been removed now". So, this is really only bringing the implementation into
line with the man page.

add SetupStage parameter to RemoteType.setup
Most remotes have an idempotent setup that can be reused for
enableremote, but in a few cases, it needs to tell which, and whether
a UUID was provided to setup was used.
This is groundwork for making initremote be able to provide a UUID.
It should not change any behavior.
Note that it would be nice to make the UUID always be provided to setup,
and make setup not need to generate and return a UUID. What prevented
this simplification is Remote.Git.gitSetup, which needs to reuse the
UUID of the git remote when setting it up, and so has to return that
UUID.

wormhole pairing appid flag day 2021-12-31
Wormhole pairing will start to provide an appid to wormhole on 2021-12-31.
An appid can't be provided now because Debian stable is going to ship a
older version of git-annex that does not provide an appid. Assumption is
that by 2021-12-31, this version of git-annex will be shipped in a Debian
stable release. If that turns out to not be the case, this change will need
to be cherry-picked into the git-annex in Debian stable, or its wormhole
pairing will break.

New annex.synccontent config setting
.. which can be set to true to make git annex sync default to --content.
This may become the default at some point in the future.
As well as being configuable by git config, it can be configured by
git-annex config to control the default behavior in all clones of a
repository.
Had to add a separate --no-content switch to we can tell if it's been
explicitly set, and should override annex.synccontent. If --content was the
default, this complication would not be necessary.

annex.autocommit can be configured via git-annex config
... to control the default behavior in all clones of a repository.
This includes a new Configurable data type, so the GitConfig type indicates
which values can be configured this way.
The implementation should be quite efficient; the config log is only read
once, and only when a Configurable value has not already been set by
git-config.
Indeed, it would be nice in the future to extend this, so that git-config
is itself only read on demand. Some commands may not need to look at the
git configuration at all.

Some optimisations to string splitting code.
Turns out that Data.List.Utils.split is slow and makes a lot of
allocations. Here's a much simpler single character splitter that behaves
the same (even in wacky corner cases) while running in half the time and
75% the allocations.
As well as being an optimisation, this helps move toward eliminating use of
missingh.
(Data.List.Split.splitOn is nearly as slow as Data.List.Utils.split and
allocates even more.)
I have not benchmarked the effect on git-annex, but would not be surprised
to see some parsing of eg, large streams from git commands run twice as
fast, and possibly in less memory.
