Comment:

 trac2274 is ready for reviewing.

 I revised the codes according to the current python statistics library. I
 couldn't implement `ixfr_deferred` and `axfr_deferred` because I couldn't
 identify where xferring is deferred on the codes. So I remove description
 regarding these counters from the above proposed change log entry.

 {{{
 nnn.   [func]          naokikambe
         New statistics items added into b10-xfrin : ixfr_running,
 axfr_running,
         and soa_in_progress.  Their values can be obtained by invoking
 "Stats
         show Xfrin" via bindctl when b10-xfrin is running.
         (Trac #2274, git TBD)
 }}}

 The some unrelated changes are included in this change but they are
 trivial and it would be better that they are fixed before this change is
 merged, I think. However even if you think we should work on a separate
 ticket about them, please point out.
