Install new git hooks in this version.
This does beg the question of what to do if git later gets eg a
post-smudge hook, that could run git-annex smudge --update. I think the
thing to do in that case would be to make git-annex smudge --update
install the new hooks. That way, as the user uses git-annex, the hook
would be created pretty quickly and without needing any extra syscalls
except for when git-annex smudge --update is called.
I considered doing something like that for installation of the
post-checkout and post-merge hooks, which would have avoided the need
for v7. But the only place it was cheap to do it would be in git-annex smudge
which could cheaply notice that smudge.log didn't exist yet and so know
the hooks needed to be installed. But since smudge used to populate pointer
files, it would be quite surprising if a single git checkout/merge failed
to update the work tree, and so that idea didn't work out.
The other reason for v7 is psychological -- users don't need to worry
about whether they might be running an old version of git-annex that
doesn't support their v7 repository very well. And bug reports about
"v6" have gotten a bit of a bad association in my head since they often
hit one of the known limitations and didn't realize it was experimental.
newtyped RepoVersion Int to avoid needing 2 comparisons in
versionSupportsUnlockedPointers etc. Also it's just nicer.

(Still need to make git annex sync --content update the adjusted branch
to expose files it downloaded, which this relies on.)

* Added arm64 Linux standalone build. (No autobuilder yet.)
* Improved termux installation process.
Added git-annex-install.sh script to avoid user needing to type as much in
termux. The scope of this script is limited; runshell handles the rest.
Runshell runs termux-fix-shebang on the shell scripts. The problem is
the bundled bin/sh script, deleting that script also works, but then the
others probably use the system Android /bin/sh, which could be old or
broken or not posix or whatever. Using termux sh to run the scripts is
better.

v6: When annex.largefiles is not configured for a file, running git add or
git commit, or otherwise using git to stage a file will add it to the annex
if the file was in the annex before, and to git otherwise. This is to avoid
accidental conversion.
Note that git-annex add's behavior has not changed, for reasons explained
in the added comment.
Performance: No added overhead when annex.largefiles is configured.
When not configured, there is an added call to catObjectMetaData,
which involves a round trip through git cat-file --batch.
However, the earlier catKeyFile primes the cache for it.

Use git update-index --refresh, since it's a little bit more
efficient and the user can be told to run it if a locked index prevents
git-annex from running it.
This also fixes the problem where an annexed file was deleted in the index
and a get of another file that uses the same key caused the index update to
add back the deleted file. update-index will not add back the deleted file.
Documented in tips/unlocked_files.mdwn the gotcha that the index update
may conflict with other operations. I can't see any way to possibly avoid
that conflict.
One new todo about a race that causes a modification to be accidentially
staged.
Note that the assistant only flushes the git command queue when it
commits a modification. I have not tested the assistant with v6 unlocked
files, but assume most users of the assistant won't care if the index
shows a file as modified for a while.

It was sorting by uuid, rather than cost!
Avoid future bugs of this kind by changing the Ord to primarily compare
by cost, with uuid only used when the cost is the same.
