8c44294087 tests: use /var/tmp by default 
On Fedora, /tmp is tmpfs, which behaves differently than ext4
(inode numbers are never reused, for example).

Use /var/tmp, which is ext4 on Fedora, to get a more realistic
test environment.

This also allows us to drop the xattr workaround.

5055f39bd5 fusefrontend: Allow to set/remove xattr on directory without read permission. 
Setting/removing extended attributes on directories was partially fixed with
commit eff35e60b63331e3e10f921792baa10b236a721d. However, on most file systems
it is also possible to do these operations without read access (see tests).

Since we cannot open a write-access fd to a directory, we have to use the
/proc/self/fd trick (already used for ListXAttr) for the other operations aswell.
For simplicity, let's separate the Linux and Darwin code again (basically revert
commit f320b76fd189a363a34bffe981aa67ab97df3362), and always use the
/proc/self/fd trick on Linux. On Darwin we use the best-effort approach with
openBackingFile() as a fallback.

More discussion about the available options is available in
https://github.com/rfjakob/gocryptfs/issues/308.

60e7a0ca9f fusefrontend: xattr: fix hang on FIFOs 
An Open() a fifo blocks until it is opened for writing.
This meant that xattr operations on FIFOs would block.
Pass O_NONBLOCK to fix that, and add a test.

5a1ebdb4f7 tests: respect TMPDIR if set 
Setting TMPDIR now allows to run the tests against
a directory of your choice, making it easier to test
different filesystems.

ae02ca1ded xattr: use LGet/LSet etc 
Support has been merged into the xattr package
( https://github.com/pkg/xattr/pull/29 ), use it.

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.

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.

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.
