Every remote that sets localpath also implements an availability that
reutrns Unavailable when a local directory is not available.
This makes external remotes, and others that get support for
availability Unavailable to be used by checkAvailable. (Which is only
used by the assistant.)
Had to keep localpath though, since other parts of the assistant use it
to eg, sync with a remote when a removable drive is plugged in.

This is groundwork for making special remotes like borg be skipped by
sync when on an offline drive.
Added AVAILABILITY UNAVAILABLE reponse and the UNAVAILABLERESPONSE extension
to the external special remote protocol. The extension is needed because
old git-annex, if it sees that response, will display a warning
message. (It does continue as if the remote is globally available, which
is acceptable, and the warning is only displayed at initremote due to
remote.name.annex-availability caching, but still it seemed best to make
this a protocol extension.)
The remote.name.annex-availability git config is no longer used any
more, and is documented as such. It was only used by external special
remotes to cache the availability, to avoid needing to start the
external process every time. Now that availability is queried as an
Annex action, the external is only started by sync (and the assistant),
when they actually check availability.

New curl binary links to libldap with a @loader_path that prevents using
the binary when the dmg is used elsewhere.
See https://github.com/datalad/git-annex/issues/170
git-annex doesn't use curl by default anyway, so it doesn't really need to
be included in the dmg.
Fix behavior when importing a tree from a directory remote when the
directory does not exist. An empty tree was imported, rather than the
import failing. Merging that tree would delete every file in the
branch, if those files had been exported to the directory before.
The problem was that dirContentsRecursive returned [] when the directory
did not exist. Better for it to throw an exception. But in commit
74f0d67aa3 back in 2012, I made it never
theow exceptions, because exceptions throw inside unsafeInterleaveIO become
untrappable when the list is being traversed.
So, changed it to list the contents of the directory before entering
unsafeInterleaveIO. So exceptions are thrown for the directory. But still
not if it's unable to list the contents of a subdirectory. That's less of a
problem, because the subdirectory does exist (or if not, it got removed
after being listed, and it's ok to not include it in the list). A
subdirectory that has permissions that don't allow listing it will have its
contents omitted from the list still.
(Might be better to have it return a type that includes indications of
errors listing contents of subdirectories?)
The rest of the changes are making callers of dirContentsRecursive
use emptyWhenDoesNotExist when they relied on the behavior of it not
throwing an exception when the directory does not exist. Note that
it's possible some callers of dirContentsRecursive that used to ignore
permissions problems listing a directory will now start throwing exceptions
on them.
The fix to the directory special remote consisted of not making its
call in listImportableContentsM use emptyWhenDoesNotExist. So it will
throw an exception as desired.

Only display warning when git-annex sync (without --content or
--no-content) is used with repositories that have preferred content
configured.

Significant startup speed increase by avoiding repeatedly checking if some
remote git-annex branch refs need to be merged when it is not newer.
One way this could happen is when there are 2 remotes that are themselves
connected. The git-annex branch on the first remote gets updated. Then the
second remote pulls from the first, and merges in its git-annex branch.
Then the local repo pulls from the second remote, and merges its git-annex
branch. At this point, a pull from the first remote will get a git-annex
branch that is not newer, but is not on the merged refs list.
In my big repo, git-annex startup time dropped from 4 seconds to 0.1 seconds.
There were 5 to 10 such remote refs out of 18 remotes.

I considered a more wide-ranging config option to make other commands
also show dead repositories. But it would be difficult to implement that
because Remote.keyLocations is used to get locations, filtering out dead
repos, and commands like get then try to use those locations. So a config
setting would make dead repos sometimes be acted on by commands.

I can't seem to get stack to resolve dependencies with Win32-2.13.4.0,
no matter what I try. Why it blows up, I don't know.
And allow-newer: true actually causes it to downgrade Win32 to the one
version that won't build. Unbelivable that allows downgrades.
So just gonna have to wait for that to get into stackage nightly, and
then stack.yaml can be updated to use that, and the changes in this
commit reverted.
