Comment (by jinmei):

 I propose beginning with a minimal python interface: just allowing an
 application to send a signed DNS message.

 And I completed that part in trac814.  It depends on #871, which is
 still in review queue, but the python wrapper code itself is ready for
 review, too.  The first commit of the branch should be ignored; it
 simply incorporates the latest version of trac871.  Also, due to my
 misoperation commit logs for this branch are tagged with [trac871].
 Sorry about that, but please don't be confused.

 Once #871 and this part of #814 are merged, we can start the task of
 updating xfrin to use TSIG (#815) (of course, xfrin would still not be
 able to verify the returned data, but it will at least be able to
 initiate an authenticated transfer).

 I propose completing other parts of the python wrapper as we implement
 other parts of the C++ API, that is, the verify part.
