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

4407ca3a4d fusefrontend: xattr: return ENODATA for security.* and system.* 
"ls -l" queries security.selinux, system.posix_acl_access, system.posix_acl_default
and throws error messages if it gets something else than ENODATA.

problem.

Also, add new corruption types to broken_fs_v1.4.

f28d85fad5 fsck: add initial implementation 
Most corruption cases except xattr should be covered.
With test filesystem.

The output is still pretty ugly. xattr support will
be added in the next commits.

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.

93849e28d8 main: move getMasterKey into initFuseFrontend 
This is where the results are used, so call it
there.

This simplifies doMount a bit because we can get
rid of the block protecting masterkey.

1a3d04ab87 Switch from private copy to pkg/xattr 
Now that https://github.com/pkg/xattr/pull/24
has been merged there is no reason to keep
our private copy.

Switch to the upstream version.

c3e12b5e68 dep: add xattr dependency 
Also, clear out Gopkg.toml. Everything is unconstrained

db778aae7d fusefrontend: handle empty xattrs efficiently 
We handle empty files by storing an actual empty file
on disk. Handle xattrs similarily and encrypt the
empty value to the empty value.

f20974c4da test_helpers: add SwitchTestParentDir 
SwitchTestParentDir changes testParentDir. This is used when you want
to perform tests on a special filesystem. For example, the xattr tests
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.

98f735ff6e tests: drop "-z" from fusermount to catch forgotten fds 
macos does not have lazy unmount, so let's not use it
on linux either.
If the unmount fails, run "lsof" to find the open file.

Also fix the first bug we found this way.

We relied on the finalizer to close a few fds.

48d5f10c79 test_helpers: use an intermediate pipe for subprocess stdout 
To Go test logic waits for stderr and stdout to close, so
when we share it with a subprocess, it will wait for it to
exit as well.

We don't want the tests to hang when the unmount fails.
