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

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.
