Simplify the code a bit.

go-fuse translates errors unknown to it into "function not
implemented", which is wrong in this case.

As ReadDirIV operates on a path anyway, opening the directory
has no clear safety advantage w.r.t. concurrent renames.
If the backing directory is a reverse-mounted gocryptfs filesystem,
each directory open is an OPENDIR, and this causes a full directory
read!
This patch improves the "ls -lR" performance of an
  DIR --> gocryptfs-reverse --> gocryptfs
chain by a factor of ~10.
OPENDIR counts for ls -lR:
  Before 15570
  After   2745

Will be needed by reverse mode.
 | 
 | 
Also, replace remaining naked syscall.Openat calls.

 | 
Let's have shorter names, and merge *_api.go into the "main"
file.
No code changes.
