Please test: tarsnap 1.0.41

[Colin Percival <cperciva@tarsnap.com>]

Hi all,

We're getting ready for version 1.0.41 of the Tarsnap client code and have
a version "1.0.40.99" ready for testing.

You can find the new code at
   https://www.tarsnap.com/download/tarsnap-autoconf-1.0.40.99.tgz
and the tarball has SHA256 hash
   25c1e77c79390cde3822b475054ae37313fefcbe462a319e09e5d8a5de808945

You can also see all the changes between 1.0.40 and this version in the
newly-public git repository at
   https://github.com/Tarsnap/tarsnap

Significant changes since tarsnap 1.0.40:

* tarsnap -c now takes a new --dry-run-metadata option, which is like the
existing --dry-run option but doesn't read file data from disk (and is thus
significantly faster).

* tarsnap -c now takes a new --noatime option, which requests that the
operating system avoid updating file and directory access times; note that
this is not supported by all operating systems, filesystems, and system
security settings.

* tarsnap now exits with an exit code of 2 if it encounters an error but the
server-side state has changed (e.g. an archive is created but not all of the
files listed on the command line existed).

* tarsnap now reads configuration from $XDG_CONFIG_HOME/tarsnap/tarsnap.conf
(or ~/.config/tarsnap/tarsnap.conf if $XDG_CONFIG_HOME is not set) in addition
to other configuration files.

* tarsnap now accepts --null-input as a synonym for --null.

* tarsnap now takes a new --null-output option which uses NUL bytes as
separators in the output of --list-archives, --print-stats, -x, and -t.

* a bug in non-SSE2 scrypt code (i.e. relevant to non-x86 systems), resulting
in a self-test failure when tarsnap is compiled with recent versions of GCC
and passphrased key files are used, has been fixed.

As usual, there are also lots of minor build fixes, harmless bug fixes, and
code cleanups.

Those of you who are using the tarsnap "experimental" .deb package set should
find that version 1.0.40.99 will install via the usual apt-get command.

Assuming I don't get any emails complaining that something is broken, I'll
be release Tarsnap version 1.0.41 in about a week.  As always, if you find
any newly introduced bugs before the official release, you'll be eligible
for double the normal Tarsnap bug bounties.
