using the cryptonite library.
While cryptohash has SHA3 support, it has not been updated for the final
version of the spec. Note that cryptonite has not been ported to all arches
that cryptohash builds on yet.

now moved to the bad directory, and the fsck proceeds. Before, the fsck immediately failed.

This way, if a system's sha1sum etc is broken, it will be tried if
git-annex was built to use it, but at least it will fall back to using
internal hashing when it fails.
A side benefit of this is that hashFile consistently throws an IOError if
the file is unable to be read. In particular, if the disk is failing with
IO errors, and external hash command is used, it used to throw a user error
with the error message from externalSHA. Now, the external hash command
will fail, that message will be printed as a warning, and it'll fall back
to the internal hash command. If the disk IO error is not intermittent, it
will re-occur, and so an IOError will be thrown.
Of course, this can mean it reads a file twice, but only in edge cases.

This will prevent backporting to wheezy, but it's time to simplify the
code.

Avoid using fileSize which maxes out at just 2 gb on Windows.
Instead, use hFileSize, which doesn't have a bounded size.
Fixes support for files > 2 gb on Windows.
Note that the InodeCache code only needs to compare a file size,
so it doesn't matter it the file size wraps. So it has been
left as-is. This was necessary both to avoid invalidating existing inode
caches, and because the code passed FileStatus around and would have become
more expensive if it called getFileSize.

This fixes all instances of " \t" in the code base. Most common case
seems to be after a "where" line; probably vim copied the two space layout
of that line.
Done as a background task while listening to episode 2 of the Type Theory
podcast.

This only performs some basic tests so far; no testing of chunking or
resuming. Also, the existing encryption type of the remote is used; it
would be good later to derive an encrypted and a non-encrypted version of
the remote and test them both.

Needed for resuming from chunks.
Url keys are considered not stable. I considered treating url keys with a
known size as stable, but just don't feel that is enough information.

This is useful because it shows users which files it checksums, vs ones
that are not present, or don't use a hash backend, or --fast

Note that the hash backends were made to stop printing a (checksum..)
message as part of this, since it showed up without a file when deciding
whether to act on a file. Should have probably removed that message a while
ago anyway, I suppose.

Mostly for the debian stable autobuilds, which have a too old version
to use the Crypto.Hash module.

SHA3 is still waiting for final standardization.
Although this is looking less likely given
https://www.cdt.org/blogs/joseph-lorenzo-hall/2409-nist-sha-3
In the meantime, cryptohash implements skein, and it's used by some of the
haskell ecosystem (for yesod sessions, IIRC), so this implementation is
likely to continue working. Also, I've talked with the cryprohash author
and he's a reasonable guy.
It makes sense to have an alternate high security hash, in case some
horrible attack is found against SHA2 tomorrow, or in case SHA3 comes out
and worst fears are realized.
I'd also like to support using skein for HMAC. But no hurry there and
a new version of cryptohash has much nicer HMAC code, so I will probably
wait until I can use that version.
