e9bb8b800c reverse: switch from GCM-SIV to AES-SIV 
GCM-SIV is not yet finalized, and the reference implemenation is
painfully slow at about 2 MB/s. Switch to AES-SIV.

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.

b558901e66 Drop deprecated "-gcmiv128" option 
The GCMIV128 feature flag is already mandatory, dropping the command
line option is the final step.

Completes https://github.com/rfjakob/gocryptfs/issues/29 .

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.

82d87ff8ed Add "-ro" (read-only) flag 
From the man page:

  **-ro**
  :      Mount the filesystem read-only

Also add a test.

e7f78135b3 Add "-allow_other" command-line option 
As requested in https://github.com/rfjakob/gocryptfs/issues/26 ,
this adds the option to allow other users to access the filesystem.

49b597f07c prefer_openssl: autodetect whether to use OpenSSL or Go GCM 
Go GCM is faster than OpenSSL if the CPU has AES instructions
and you are running Go 1.6+.

The "-openssl" option now defaults to "auto".

"gocryptfs -debug -version" displays the result of the autodetection.

See https://github.com/rfjakob/gocryptfs/issues/23 for details and
benchmarks.

1caa925868 Increase GCM IV size from 96 to 128 bits 
This pushes back the birthday bound for collisions to make it virtually
irrelevant.
