Create *InfoData objects instead of reusing *Resource objects

This is probably best from a code-cleanliness perspective anyways,
but the rationale is that tightly coupling the resources to the
info responses was a straightjacket that required all status
values and fields to be directly available on the resource. With
this change, I already was able to get rid of the preMarshal()
hackery, and I will be able to get rid of cloneWithLinkedStatus()
and most of the contents of cloneProjectedAtTime() for non-domains.
