This reverts commit a458d69d94b2a7506395e7a24e5c2a9146791553.

b10-stats_test.py

 - The stats httpd doesn't need to return an argument when it's
   shutting down.

 - The testcase sends the 'status' command or the 'shutdown' command
   to the stats or the stats httpd when they started, and then their
   returned values are checked.

 - A hostname (canonical name of host) is not acceptable in listen_on
   configuration.

 - A default port number(starting number for search) is added in args
   of the function get_availaddr.

 - don't use DEFAULT_CONFIG

 - move up mccs.start and open_httpd to __init__(). It takes time to
   do these functions, and an extra sleep is needed in unittests.

 - set running to False in http stopping

 - use validate_config in module_spec class

 - don't close/open http before it's opened

remove unused messages from the message file add test logging names
into unittest scripts

 - remove "stats-schema.spec" setting and getting statistics data
   schema via this spec file

 - add "version" item in DEFAULT_CONFIG

 - get the address family by socket.getaddrinfo function with specified
   server_address in advance, and create HttpServer object once, in stead of
   creating double HttpServer objects for IPv6 and IPv4 in the prior code
   (It is aimed for avoiding to fail to close the once opened sockets.)

 - open HTTP port in start method

 - avoid calling config_handler recursively in the except statement

 - create XML, XSD, XSL documents after getting statistics data and schema from
   remote stats module via CC session

 - definitely close once opened template file object

for python logging message scripts.
