Comment (by jinmei):

 trac1570 is ready for review.

 The branch has become a bit bigger than I originally expected, so
 the reviewer may want to divide the review into several stages.  Here
 are some hints:

 - The first few commits are cleanup and refactoring in the tests for
   further extension.  This part can be reviewed separately.
   (from 848e9d9 to 00de2fb)
 - The main protocol work consists of several (mostly) independent
   scenarios:
   - From 47bca52 to 32d9c52: major case, DS query handled in the parent
   - 0d1406f: DS query that happens to be sent to the child
   - afc721f to efd87c8: handled the "grand parent" problem
   - f364574: special consideration for ./DS query
 - Other cleanups.  The last one (53cde03) is not directly related to
   this task, but I thought it would be good to test it explicitly
   while I worked on the branch.

 I'd consider this work a kind of bug fix, so I think it's worth a
 changelog:
 {{{
 374.?   [bug]           jinmei, vorner
         The new query handling module of b10-auth now handles type DS
         query correctly.
         (Trac #1570, git TBD)
 }}}
