Jakob Unterwurzacher 97743858ce performance.txt: update result for governor = performance
Also add big signs where the cpu has changed, as the results
are not comparable when the cpu is different.

Also update encfs results.

Jakob Unterwurzacher d5ce340c02 merge prefer_openssl package into stupidgcm
Now that I have discovered golang.org/x/sys/cpu and that Go
versions below 1.6 are uncommon, there was not much useful
code left in prefer_openssl.

Merge the remains into stupidgcm.

Jakob Unterwurzacher a48d7fac2c main: haveFusermount2: respect PATH environment variable
Use exec.LookPath() to find fusermount in the user's PATH
first. Fall back to /bin/fusermount for the case that PATH
is not set, like go-fuse does.

Jakob Unterwurzacher db43bfc4c0 main: detect fusermount3 and don't add `nonempty`
fusermount3 (i.e. fusermount from libfuse 3.x) has dropped
the `nonempty` option.

Detect fusermount3 and don't add `nonempty` in this case.

Jakob Unterwurzacher 9178aa1534 MANPAGE: describe how to unmount, and that default options are fine
Feedback received during the recent Go user group. If you haven't
used FUSE before, you don't know how to unmount, and it was not
described in the man page!

As for the options, there are many, and new users are intimidated
by it. State clearly that defaults are fine.

Jakob Unterwurzacher e4148028af fusefrontend: warn about missing diriv
The comment is outdated, at this point, we should
really not get any errors from ReadDirIVAt.

The change is best seen when running the fsck tests. Before:

  fsck: error opening dir "missing_diriv": 2=no such file or directory

After:

  OpenDir "K2m0E6qzIfoLkVZJanoUiQ": could not read gocryptfs.diriv: no such file or directory
  fsck: error opening dir "missing_diriv": 5=input/output error

See https://github.com/rfjakob/gocryptfs/issues/403 , where
the extra info would have been helpful.

Jakob Unterwurzacher 93939961f5 fusefrontend: don't return EIO on directory with corrupt file names
This was meant as a way to inform the user that
something is very wrong, however, users are hitting
the condition on MacOS due to ".DS_Store" files, and
also on NFS due to ".nfsXXX" files.

Drop the whole thing as it seems to cause more pain
than gain.

Jakob Unterwurzacher 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.

Jakob Unterwurzacher 00af4f4864 fusefrontend: unregister from openfiletable before closing the fd
Closing the fd means the inode number may be reused immediately

beforehand!
