5073459296 Revert "getdents_c: read from two threads" 
This made the code more complicated without reproducing
the problem.

This reverts commit 77632b7554.

77632b7554 getdents_c: read from two threads 
This was an attempt to make the C code more
similar to Go (which also reads from multiple threads).

However, I still could not repro the ENOENT problems.

a56e7cc5ac sshfs-benchmark.bash: fix locale trouble and move to tests 
Locale trouble was

   sshfs-benchmark.bash: line 31: printf: 4.71: invalid number

because printf expected "4,71" in the German locale.
Force the C locale.

Let's get some reproducible numbers for
https://github.com/rfjakob/gocryptfs/issues/481
and
https://github.com/rfjakob/gocryptfs/issues/410

Example run:

$ ./sshfs-benchmark.bash nuetzlich.net
working directory: /tmp/sshfs-benchmark.bash.vu4
sshfs mounted: nuetzlich.net:/tmp -> sshfs.mnt
gocryptfs mounted: sshfs.mnt/sshfs-benchmark.bash.KM9/gocryptfs.crypt -> gocryptfs.mnt

                         sshfs  gocryptfs-on-sshfs
git init                  1.68               11.23

7c053e67f2 contrib: add gocryptfs-maybe.bash 
Conditionally try to mount a gocryptfs filesystem. If either
 * CIPHERDIR does not exist OR
 * something is already mounted on MOUNTPOINT
 print a message to stdout (not stderr!) but exit with 0.

 This is meant to be called from automated mount systems like pam_mount,
 where you want to avoid error messages if the filesystem does not exist,
 or duplicate mounts if the filesystem has already been mounted.

and the gocryptfs_pam_mount.bash is no longer needed since
commit 9cf3ced0ce .

a985096b50 contrib: pam_mount: check if something is already mounted on DST 
pam_mount is supposed to check that as well, but it seems to get confused
by the "command#path" syntax used for FUSE. Let's do it here.
