f054353bd3 reverse: make gocryptfs.conf mapping plaintextnames-aware 
Only in plaintextnames-mode AND with the config file at the
default location it will be mapped into the mountpoint.

Also adds a test for that.

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

All gocryptfs messages already go to syslog, but the messages

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...

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.

b97268c948 configfile: bake the "Creator" gocryptfs version into the file 
This field is added for the convenience of users and
may help them to identify which gocryptfs version
they need to mount a filesystem.

The same information is essentially contained in FeatureFlags,
but this is more difficult to decode for humans.

It is completely ignored programmatically (also by older gocryptfs
versions).
