non file system based implementation of nio.file

[Tigran Mkrtchyan]

you can have a look here:

http://www.dcache.org/WebSVN/filedetails.php?repname=Chimera&path=%2Ftrunk%2Forg%2Fdcache%2Fchimera%2FFsInode.java

Currently it' more like mix of FileRef and FileSystem which can be 
cleaned up if necessary.
