Could you add a comment about this new functions? It's quite different
from every other function in this header which deal with a xenstore
path. Every other function use "${node}/${key}" (As explain in the
comment above xs_node_vscanf()), but this one uses a printf format in
`node_fmt` (which could probably better be named `path_fmt` instead).

Otherwise, patch looks fine to me.

Cheers,
