Subject: Changed the way a VFS is initialised.  The vfs_init() function is
 executed from the VFS object file and it returns a pointer to a vfs_ops
 structure.  If any of the function pointers in vfs_ops are NULL, then they
 are replaced with the standard disk functions.  This should allow
 disk-related VFS modules to be easily added.  I've written an auditing VFS
 module which logs various calls (connect, disconnect, mkdir, rmdir, open and
 a few others) to syslog in a couple of pages of code.

Thanks to tridge for various useful suggestions.
(This used to be commit 346c78d7078d87bc95abc274f2bc66476aeee54c)
