Kernel: Pass a Custody instead of Inode to VFS methods

Browse source 
VFS no longer deals with inodes in public API, only with custodies and file
descriptions. Talk directly to the file system if you need to operate on a
inode. In most cases you actually want to go though VFS, to get proper
permission check and other niceties. For this to work, you have to provide a
custody, which describes *how* you have opened the inode, not just what the
inode is.
