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.

12b32aa06c Improved xattr handling on non-linux systems (#227) 
* Fixed xattr filtering for MacOS. "system." and "user." prefixes are only relevant for Linux.
* Small cleanup and additional tests.

Leftover fds can cause an unmount failure like this later:

so try to catch them early.

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

f28d85fad5 fsck: add initial implementation

With test filesystem.

fb06c65ee9 fusefronted: reject oversized Read and Write requests 
This should not happen via FUSE as the kernel caps the size,
but with fsck we have the first user that calls Read directly.
For symmetry, check it for Write as well.

rid of the block protecting masterkey.

f20974c4da test_helpers: add SwitchTestParentDir

cannot run on tmpfs and use /var/tmp instead of /tmp.

8373410678 macos: extractloop.sh: exclude symlink & mute ln error message 
Extracting the symlink fails with

	linux-3.0/arch/microblaze/boot/dts/system.dts: Can't set permissions to 0755

so just exclude it.

The ln error Looks scary but is harmless, so get rid of it.
The symlink is only created to make it more convenient to view the
csv log.
