53d6a9999d main: accept -dev, -nodev, -suid, -nosuid, -exec, -noexec
When mounted via /etc/fstab like this,

  /a /b fuse.gocryptfs default 0 0

we always get extra options passed. As reported by @mahkoh
at https://github.com/rfjakob/gocryptfs/pull/233 :

  mount passes `-o noexec` if `-o user` is set and `-o exec` is not set.
  If both `-o user` and `-o exec` are set, it passes `-o exec`.

Make these options work, and in addtion, also make -suid and -rw
work the same way.

e29a81efc3 main: make prefixOArgs errors testable
By returning an error instead of calling os.Exit,
error cases can be tested easily. Error cases
were not tested until now.

e25d551e18 crossbuild.bash: call "set -x" late
Fedora 28 executes A LOT of stuff from /usr/share/Modules/
on bash startup. Having -x in the shebang means we see
it all.

7b00681807 xattr: return EOPNOTSUPP for unsupported attributes
mv is unhappy when we return EPERM when it tries to set
system.posix_acl_access:

   mv: preserving permissions for ‘b/x’: Operation not permitted

Now we return EOPNOTSUPP like tmpfs does and mv seems happy.

a41ec2028c xattr: optimize storage, store as binary instead of bae64
Values a binary-safe, there is no need to base64-encode them.

Old, base64-encoded values are supported transparently
on reading. Writing xattr values now always writes them binary.

fc8fca04a8 tests: example_filesystems: create a private copy in /tmp
The tests write to the example_filesystems folder, which
1) May leave your source tree in a modified state
2) Triggers test failures when the fsck tests run concurrently,
   which happens on Travis CI every now and then.

Fix both problem by copying the example_filesystems folder
to a private location in /tmp.

fe3890688a fusefrontend: xattr: return ENOSYS on unsupported flags
We previously returned EPERM to prevent the kernel from
blacklisting our xattr support once we get an unsupported
flag, but this causes lots of trouble on MacOS:
Cannot save files from GUI apps, see
https://github.com/rfjakob/gocryptfs/issues/229

Returning ENOSYS triggers the dotfiles fallback on MacOS
and fixes the issue.

4e5783591f fsck: report skipped corrupt files
OpenDir and ListXAttr skip over corrupt entries,
readFileID treats files the are too small as empty.
This improves usability in the face of corruption,
but hides the problem in a log message instead of
putting it in the return code.

Create a channel to report these corruptions to fsck
so it can report them to the user.

Also update the manpage and the changelog with the -fsck option.

Closes https://github.com/rfjakob/gocryptfs/issues/191
