3288d98703 fusefrontend: fix PlaintextNames versions of Mkdir, Rmdir
The "!fs.args.DirIV" special case was removed by b17f0465c7
but that, by accident, also removed the handling for
PlaintextNames.

Re-add it as an explicit PlaintextNames special case.

Also adds support for removing directories that miss their
gocryptfs.diriv file for some reason.

547ddf4264 tlog: switch default logger to syslog
...unless "-nosyslog" is passed.

All gocryptfs messages already go to syslog, but the messages
that the go-fuse lib emits were still printed to stdout.

Fixes issue #13 ( https://github.com/rfjakob/gocryptfs/issues/13 )

15b88756ad main: add "-o" option to enable "suid" and "dev"
Device files and suid binaries are often not needed when running
gocryptfs as root. As they are potentially dangerous, let the
user enable them explicitely via the new "-o" option instead of
always enabling them when running as root.

0115588680 main, fusefrontend: enable suid functionality
FUSE filesystems are mounted with "nosuid" by default. If we run as root,
we can use device files by passing the opposite mount option, "suid".

Also we have to use syscall.Chmod instead of os.Chmod because the
portability translation layer "syscallMode" messes up the sgid
and suid bits.

Fixes 70% of the failures in xfstests generic/193. The remaining are
related to truncate, but we err on the safe side:

    $ diff -u tests/generic/193.out /home/jakob/src/fuse-xfstests/results//generic/193.out.bad
    [...]
     check that suid/sgid bits are cleared after successful truncate...

38767ab527 fuserfrontend: support truncate(2) by wrapping ftruncate(2)
Support truncate(2) by opening the file and calling ftruncate(2)
While the glibc "truncate" wrapper seems to always use ftruncate, fsstress from
xfstests uses this a lot by calling "truncate64" directly.

8a2e1a543a tests: add v0.7-plaintextnames example filesystem
The v0.6-plaintextnames example FS lacks the GCMIV128 feature
flag, is no longer mountable and can no longer be used for testing.

There have been no format changes to "-plaintextnames" since then.

1dcafb99ff main: drop "on-disk format" from -version output, add Go version
As v0.4 introduced ext4-style feature flags, the on-disk format version
is unlinkely to change. Drop it from the version output to reduce
clutter. Use "gocryptfs -version -debug" to see it.

Add the Go version string because only Go 1.6 and newer have an optimized
AES-GCM implementation. This will help users to understand the performance
of their build.

5b1eed35ee fusefrontend: Utimens: convert ENOENT to EBADF
If /proc/self/fd/X did not exist, the actual error is that the file
descriptor was invalid.

go-fuse's pathfs prefers using an open fd even for path-based operations
but does not take any locks to prevent the fd from being closed.
Instead, it retries the operation by path if it get EBADF. So this
change allows the retry logic to work correctly.

This fixes the error

    rsync: failed to set times on "/tmp/ping.Kgw.mnt/linux-3.0/[...]/.dvb_demux.c.N7YlEM":
    No such file or directory (2)

that was triggered by pingpong-rsync.bash.

Mounts two gocryptfs filesystems, "ping" and "pong" and moves the

When called as "pingpong-rsync.bash" it uses "rsync --remove-source-files"
for moving the files, otherwise plain "mv".

5da292828c fusefrontend: fix chown on dangling symlinks
We (actually, go-fuse) used to call Chown() instead of Lchown()
which meant that the operation would fail on dangling symlinks.

Fix this by calling os.Lchown() ourself. Also add a test case
for this.

c2a5303eeb tests: split example_filesystems into its own package
Running these tests from integration_tests' TestMain() was awkward
because they were run twice with unchanged settings.
integration_tests tests everything with OpenSSL and with native
Go crypto, but this does not take affect for the example filesystems.

To make this work, test_helpers is also split into its own package.
