Fix the revision number in Changelog. Remove the folder /src/lib/python/isc/utils(which was forgot to removed in r3382. ), trivial, skip review.

-class NoPollMixIn:
-    '''This is a mix-in class to override the function serve_forever()
-    and shutdown() in class socketserver.BaseServer.
-
-    As commented in the module source code,  serve_forever() in
-    socketserver.BaseServer uses polling for a shutdown request, which
-    "reduces the responsiveness to a shutdown request and wastes cpu at
-    all other times."
-
-    This class fixes this problem by introducing internal message
-    passing via a separate socket. Note, however, that according to
-    the module documentation serve_forever() and shutdown() are not
-    categorized as functions that can be overridden via mix-ins.  So
-    this mix-in class may not be compatible with future versions of
-    socketserver.  It should be considered a short term workaround
-    until the original implementation is fixed.
-
-    The NoPollMixIn class should be used together with
-    socketserver.BaseServer or some derived classes of it, and it must
-    be placed before the corresponding socketserver class.  In
-    addition, the constructor of this mix-in must be called
-    explicitely in the derived class.  For example, a basic TCP server
-    without the problem of polling is created as follows:
-
-       class MyServer(NoPollMixIn, socketserver.TCPServer):
-           def __init__(...):
-               ...
-               NoPollMixIn.__init__(self)
-               ...
-
-    To shutdown the server correctly, the serve_forever() method must
-    be run in a separate thread, and shutdown() must be called from
-    some other thread.
-    '''
-    def __init__(self):
-        self.__read_sock, self.__write_sock = socket.socketpair()
-        self._is_shut_down = threading.Event()
-
-    def serve_forever(self, poll_interval=None):
-        ''' Overrides the serve_forever([poll_interval]) in class
-        socketserver.BaseServer.
-
-        It uses a socketpair to wake up the select when shutdown() is
-        called in anther thread.  Note, parameter 'poll_interval' is
-        just used for interface compatibility; it's never used in this
-        function.
-        '''        
-        while True:
-            # block until the self.socket or self.__read_sock is readable
-            try:
-                r, w, e = select.select([self, self.__read_sock], [], [])
-            except select.error as err:
-                if err.args[0] == EINTR:
-                    continue
-                else:
