- introduced the b10-stats daemon running in the lettuce test suite "Xfrin
  incoming notify handling"
- renamed retransfer_master.conf to retransfer_master.conf.orig because of the
  config change in the lettuce suite

- updated the mock classes for testing counters
- added tests of each counter with a specified zone name

- added setting up the counter handlers for IPv4 and IPv6
- added counting notifications in the NotifyOut class
- fixed a trivial typo

- updated the mock classes for testing counters
- added tests checking each counter exactly incrementing
- added tests for the XfroutCounter class
- added a test for handling the getstats command

- added the new class XfroutCounter
  It is intended for producing incrementers of the counters based on the
  statistics spec and for outputting statistics data format to passed to the
  b10-stats daemon.
- added counter handlers passed to the NotifyOut object and the XfroutSession
  object
- added handling of the getstats command
- added counting xfr requests in the XfroutSession class
- updated the UnixSockServer class for taking over the counter handlers

It would be logged when b10-xfrout receives the "getstats" command from the
b10-stats daemon.

added a definition of per-zone counters: notifyoutv4, notifyoutv6, xfrrej, and
xfrreqdone.

Some review on jabber. If necessary, jelte can update later.

okayed by muks

and updated entries for style (even old entries).

since not backward incompatible or operational changes.

This is only needed so I don't have differences later.
This won't be needed once we stop including generated docs in the
source tree.

referring to #2066.

BasicRRset implements a dummy getRRsigDataCount() which returns 0
(as getRRsig() returns NULL without throwing).

The method was renamed different to what is asked in the bug, so that
the new name is consistent with other AbstractRRset methods for RRSIGs.

This seems to be required in our coding style.
