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.

Useful for dropping old objects from cache repositories.
But also, quite a genrally useful thing to have..
Rather than imitiating find's -atime and other options, all of which are
pretty horrible to use, I made this match files accessed within a time
period, using the same duration format used by git-annex schedule and
--limit-time
In passing, changed the --limit-time option parser to parse the
duration, instead of having it later throw an error.

Added remote.name.annex-speculate-present config that can be used to
make cache remotes.
Implemented it in Remote.keyPossibilities, which is used by the
get/move/copy/mirror commands, and nothing else. This way, things like
whereis will not show content that's speculatively present.
The assistant and sync --content were not using Remote.keyPossibilities,
and were changed to use it.
The efficiency hit should be small; Remote.keyPossibilities is only
used before transferring a file, which is the expensive operation.
And, it's only doing one lookup of the remoteList and a very cheap
filter over it.
Note that, git-annex still updates the location log when copying content
to a remote with annex-speculate-present set. In this case, the location
tracking will indicate that content is present in the remote. This may
not be wanted for caches, or may not be a real problem for them. TBD.

Support working trees set up by git-worktree, by setting up some symlinks
such that git-annex links work right.
Also improved support for repositories created with --separate-git-dir.
At least recent git makes a .git file for those (older may have used a
symlink?), so that also needs to be converted to a symlink.

5f0f063a7a documented it as being
configured automatically, but the code never did that. Rather than try
to hard-code whatever urls amazon uses for its buckets, it seems better
to ask the user to find the url and set it.
Security fix! Allowing any schemes, particularly file: and
possibly others like scp: allowed file exfiltration by anyone who had
write access to the git repository, since they could add an annexed file
using such an url, or using an url that redirected to such an url,
and wait for the victim to get it into their repository and send them a copy.
* Added annex.security.allowed-url-schemes setting, which defaults
to only allowing http and https URLs. Note especially that file:/
is no longer enabled by default.
* Removed annex.web-download-command, since its interface does not allow
supporting annex.security.allowed-url-schemes across redirects.
If you used this setting, you may want to instead use annex.web-options
to pass options to curl.
With annex.web-download-command removed, nearly all url accesses in
git-annex are made via Utility.Url via http-client or curl. http-client
only supports http and https, so no problem there.
(Disabling one and not the other is not implemented.)
Used curl --proto to limit the allowed url schemes.
Note that this will cause git annex fsck --from web to mark files using
a disallowed url scheme as not being present in the web. That seems
acceptable; fsck --from web also does that when a web server is not available.
youtube-dl already disabled file: itself (probably for similar
reasons). The scheme check was also added to youtube-dl urls for
completeness, although that check won't catch any redirects it might
follow. But youtube-dl goes off and does its own thing with other
protocols anyway, so that's fine.
Special remotes that support other domain-specific url schemes are not
affected by this change. In the bittorrent remote, aria2c can still
download magnet: links. The download of the .torrent file is
otherwise now limited by annex.security.allowed-url-schemes.
This does not address any external special remotes that might download
an url themselves. Current thinking is all external special remotes will
need to be audited for this problem, although many of them will use
http libraries that only support http and not curl's menagarie.
The related problem of accessing private localhost and LAN urls is not
addressed by this commit.

runshell: Use proot when running on Android, to work around Android 8's
ill-advised seccomp filtering of system calls, including ones crucial for
reliable thread locking. (This will only work with termux's version of
proot.)

Assistant: Integrate with Termux:Boot, so when it's installed, the
assistant is autostarted on boot.
This commit was sponsored by Boyd Stephen Smith Jr. on Patreon.
Added some tweaks to make git-annex work in termux on Android. The regular
arm standalone tarball now works in termux.
I guess the test for "$base/bin/git" is not really necessary, since it
tests for git-annex. Since that gets deleted on android, removed that test.
These are pretty hackish hacks, especially adding it to PATH. The goal is
to make it work well enough out of the box on Android.

tips/automatically_adding_metadata/pre-commit-annex: Fix to not silently
skip filenames containing non-ascii characters.
git diff-index defaults to munging non-ascii characters. Using -z makes
it not do that, and then we just change the nulls to newlines.

The feeds for playlists seem pretty broken, since they have the oldest
items first and are truncated, so after a few dozen items, new items
never appear on them. Channel feeds don't currently have this breakage
(although perhaps Google will find a way to break them eventually..)
