At the moment, in forward mode you can only encrypt paths
and in reverse mode you can only decrypt paths.

f054353bd3 reverse: make gocryptfs.conf mapping plaintextnames-aware 
Only in plaintextnames-mode AND with the config file at the
default location it will be mapped into the mountpoint.

Also adds a test for that.

db72a4489d fusefrontend_reverse cast Stat_t.Dev to uint64 (#44) 
The [Stat_t.Dev](https://golang.org/pkg/syscall/#Stat_t) docs say `Dev` is a `unit64`, but on [macOS amd64](https://golang.org/src/syscall/ztypes_darwin_amd64.go) it's an `int32`.

52a6f4f71e reverse: add longnameParentCache 
findLongnameParent has to read the whole directory to find the
right file; add a simple cache to avoid most directory scans.

a6a7b424f8 reverse: resolve long names in Open and GetAttr 
The last patch added functionality for generating gocryptfs.longname.*
files, this patch adds support for mapping them back to the full
filenames.

Note that resolving a long name needs a full readdir. A cache
will be implemented later on to improve performance.
