fuse: add file handle to getattr operation

Browse source 
Add necessary protocol changes for supplying a file handle with the getattr
operation.  Step the API version to 7.9.

This patch doesn't actually supply the file handle, because that needs some
kind of VFS support, which we haven't yet been able to agree upon.
