 See #2056 for background.  This is another one of such things,
 referring to trac1607exp branch:

 {{{#!cpp
     // Called to get origin NS or SOA (although the method is
 generalized).
     // Default version: internally calls find() for the origin name and
 the
     //   given type, and return the result.
     // Optimized in-memory version: it has a shortcut to the origin node.
     //   get directly the requested RRset there and return it.
 }}}

 And in this ticket we'll only need to do the "default version".  It
 should be essentially straightforward refactoring.
