Makes sense, but isn't immediately obvious from your commit message.
What about:
qom: Make object_resolve_path_component() path argument const
Navigating well-known paths from an object like
object_resolve_path_component(foo, "bar")
is perfectly legitimate, but doesn't compile, because the second
parameter lacks const. Fix that.
