9a217ce786 pathiv: move block IV algorithm into this package 
This was implemented in fusefrontend_reverse, but we need it
in fusefrontend as well. Move the algorithm into pathiv.BlockIV().

d202a456f5 pathiv: move derivedIVContainer into the package 
...under the new name "FileIVs".

This will also be used by forward mode.

9ecf2d1a3f fusefrontend_reverse: store derived values for hard-linked files 
With hard links, the path to a file is not unique. This means
that the ciphertext data depends on the path that is used to access
the files.

Fix that by storing the derived values when we encounter a hard-linked
file. This means that the first path wins.

internal/nametransform/raw64_go1.5.go:10:2: exported const HaveRaw64 should have comment (or a comment on this block) or be unexported

a2510efe12 reverse: use per-purpose nonce generation 
Also pull all the deterministic nonce code into fusefrontend_reverse
to greatly simplify the normal code path.

Also add an incomplete read implementation.
