Thanks to previous work in 11cc9f1933,
this is almost entirely free, it only needs to do some additional map
lookups and math.
The strictness annotations keep the memory use from blowing up.

Fix a crash opening sqlite databases when run in a non-unicode locale,
with a remote that uses a non-unicode filepath. In that situation
converting to Text fails.
The fix needs git-annex to be built with persistent-sqlite 2.13.3.
Building against older versions still works, but that version is used when
building with stack.
Database.RawFilePath is a lot of code copied from persistent-sqlite and
lightly modified, since only 1 function in persistent-sqlite was made to
support RawFilePath. This is a bit of a pain, and I hope that
persistent-sqlite will eventually switch to using OsPath, allowing this
module to be removed from git-annex.

When importing from a special remote, support preferred content expressions
that use terms that match on keys (eg "present", "copies=1"). Such terms
are ignored when importing, since the key is not known yet.
When "standard" or "groupwanted" is used, the terms in those
expressions also get pruned accordingly.
This does allow setting preferred content to "not (copies=1)" to make a
special remote into a "source" type of repository. Importing from it will
import all files. Then exporting to it will drop all files from it.
In the case of setting preferred content to "present", it's pruned on
import, so everything gets imported from it. Then on export, it's applied,
and everything in it is left on it, and no new content is exported to it.
Since the old behavior on these preferred content expressions was for
importtree to error out, there's no backwards compatability to worry about.
Except that sync/pull/etc will now import where before it errored out.
migrate: Support adding size to URL keys that were added with --relaxed, by
running eg: git-annex migrate --backend=URL foo
Since url keys cannot be generated, that used to fail. Make it notice that
the backend is not changed, and just get the size of the content.

pull, sync: When operating on content, automatically hard link objects
that have been migrated.
Added annex.syncmigrations config that can be set to false to prevent
pull and sync from migrating object content.
I think that true is a good default for this config, because it avoids
users having to re-download migrated content or learning about migration.
But, some users will surely not like it, whether because it does take some
time (especially for the first git-annex branch scan when there is a long
history), or because they want to deal with it manually, or because their
filesystem doesn't support hard links and they don't want it to copy
objects.

And avoid migrate --update/--aply migrating when the new key was already
present in the repository, and got dropped. Luckily, the location log
allows distinguishing from the new key never having been present!
That is mostly useful for --apply because otherwise dropped files would
keep coming back until the old objects were reaped as unused. But it
seemed to make sense to also do it for --update. for consistency in edge
cases if nothing else. One case where --update can use it is when one
branch got migrated earlier, and we dropped the file, and now another
branch has migrated the same file.
