Add support for the create, link, symlink, unlink, mkdir, rmdir and
rename VFS operations to the in-kernel AFS filesystem.
Also:
(1) Fix dentry and inode revalidation. d_revalidate should only look at
state of the dentry. Revalidation of the contents of an inode pointed to
by a dentry is now separate.
(2) Fix afs_lookup() to hash negative dentries as well as positive ones.
