3409ade272 forcedecode: tighten checks
...and fix a few golint issues and print a scary warning message on mount.

Also, force the fs to ro,noexec.

f1945c4daa Add -forcedecode
Force decode of encrypted files even if the integrity check fails, instead of
failing with an IO error. Warning messages are still printed to syslog if corrupted
files are encountered.
It can be useful to recover files from disks with bad sectors or other corrupted
media.

Closes https://github.com/rfjakob/gocryptfs/pull/102 .

1ff4ae56c1 README: use pre-rendered PNG logo
This keeps the README working even if nuetzlich.net is unavailable.
We use a PNG because github disallows embedding local SVGs.

0f8d3318a3 main, fusefrontend: add "-noprealloc" option
Preallocation is very slow on hdds that run btrfs. Give the
user the option to disable it. This greatly speeds up small file
operations but reduces the robustness against out-of-space errors.

Also add the option to the man page.

9cf3ced0ce main: also accept options at the end via "-o"
For compatability with mount(1), options are also accepted as
"-o COMMA-SEPARATED-OPTIONS" at the end of the command line.
For example, "-o q,zerokey" is equivalent to "-q -zerokey".

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.

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.

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.
