53257f4ee5 nametransform: better error code on invalid diriv length
go-fuse translates errors unknown to it into "function not
implemented", which is wrong in this case.

b34a665da4 nametransform: implement ReadDirIV without Openat
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

7e92ebe16a Rename nametransform, contentenc source files
Let's have shorter names, and merge *_api.go into the "main"
file.

No code changes.
