c1d7e38761 findholes: add --create, --verify 
Also, change the logic for the segment walk to not
rely on the total size. cp does not use the total
size either, and we miss bugs by cheating!

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

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.
