6da2a69018 test_helpers: VerifySize: don't complain about ino mismatch 
The inode number is not stable with `-sharedstorage`.
Ignore it.

Failure was like this:

f8ad2ac3e2 dircache: increase cache size & lifetime 
Looking at the dircache debug output, we see
that a "git status" workload has a very bad
cache hit rate because the entries expire or
get evicted before they can be reused.

Increase both cache size and lifetime for
a 4x speedup:

Before: 75s
After:  17s

c19baa10f8 tests: use t.Name() 
We did not use t.Name() as it was not available
before Go 1.8. Now the oldest Go version we support is
Go 1.11, so we can use it.

31ff557f85 tests: also check inode number in VerifySize 
Check Stat() vs Fstat() result. Not very useful
at the moment as the kernel never seems to call Fstat().

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.

1fb18f4a9e tests: filter leaked fds by prefix 
When running

  $ go test ./tests/matrix/

in isolation, it failed like this:

  fd leak? before, after:
  [0r=/dev/null 3w=/dev/null 5r=/proc/8078/fd (hidden:4)]
  [0r=/dev/null 3w=/dev/null 5w=/tmp/go-build366655199/b001/testlog.txt 7r=/proc/8078/fd (hidden:4)]

Filter by prefix to get rid of this spurious test failure.

772afa93f9 tests: add fd leak retry logic to UnmountErr, really return error 
Give the gocryptfs process one extra millisecond to close
files. Allows us to drop several other sleeps.

UnmountErr now really returns an error when it detects an fd leak
instead of just printing a message.

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.
