9768376bd1 tests: add TestXfs124 
This test reproduces the problem xfstests generic/124 uncovered.
The warning itself is harmless, but we should either (1) add locking
so that this cannot happen anymore or (2) drop the warning.

Currently fails:

9ab11aa4d7 fusefrontend: drop writeOnly flag 
We do not have to track the writeOnly status because the kernel
will not forward read requests on a write-only FD to us anyway.

I have verified this behavoir manually on a 4.10.8 kernel and also
added a testcase.

f1244b6d06 tests: recreate v1.3 example filesystem 
The filesystem was created with a gocryptfs version that ignored
the HKDF flag (hence everything was actually encrypted WITHOUT hkdf).

Fix it by recreating it.

a80d798c2d tests: reverse: don't run tests that ignore "-plaintextnames" twice 
TestMain() runs all tests twice, once with plaintextnames=true and once
with false. Several tests mount their own filesystem and ignore the
plaintextnames variable. It makes no sense to run them twice, so
skip execution when plaintextnames is set.

d48ccb3dda Report correct symbolic link dentry sizes 
Prior to this commit, gocryptfs's reverse mode did not report correct
directory entry sizes for symbolic links, where the dentry size needs to
be the same as the length of a string containing the target path.

This commit corrects this issue and adds a test case to verify the
correctness of the implementation.

This issue was discovered during the use of a strict file copying program
on a reverse-mounted gocryptfs file system.

8adfbf2dc3 Check for trailing garbage after the password 
From the comment:

// CheckTrailingGarbage tries to read one byte from stdin and exits with a
// fatal error if the read returns any data.
// This is meant to be called after reading the password, when there is no more
// data expected. This helps to catch problems with third-party tools that
// interface with gocryptfs.
