Add wrappers to set and clear the callback promise and to mark a directory
as invalidated, and add tracepoints to track these events:
(1) afs_cb_promise: Log when a callback promise is set on a vnode.
(2) afs_vnode_invalid: Log when the server's callback promise for a vnode
is no longer valid and we need to refetch the vnode metadata.
(3) afs_dir_invalid: Log when the contents of a directory are marked
invalid and requiring refetching from the server and the cache
invalidating.
and two tracepoints to record data version number management:
(4) afs_set_dv: Log when the DV is recorded on a vnode.
(5) afs_dv_mismatch: Log when the DV recorded on a vnode plus the expected
delta for the operation does not match the DV we got back from the
server.
