libfs

Al added fs/libfs.c for common library routines used by filesysems a while ago, but we have a lot more such library funcions, say fs/exportfs/ or stuff scribbled all over the core VFS files.

This patch adds a fs/libfs/ dir instead, starting with simple.c (simple, ramfs-based filesystems), symlink.c (pagecache-based symlink code) and export.c (Neil's common export helpers). In the long term I think it's a good idea too, to have the prototypes for all this (and whatever we more over) to <linux/libfs.h> so it's clear they are only intended for filesystem driver, and we don't get into situations like those people trying to use do_generic_file_read from inkernel servers like in 2.4.

(I've send this as combined BK/plain patch because the BK patch
can track the renames, but the plain patch works fine aswell)

You can import this changeset into BK by piping this whole message to:
'| bk receive [path to repository]' or apply the patch as usual.
