323.	[bug]		jinmei
	b10-xfrout incorrectly skipped adding TSIG RRs to some
	intermediate responses (when TSIG is to be used for the
	responses).  While RFC2845 optionally allows to skip intermediate
	TSIGs (as long as the digest for the skipped part was included
	in a later TSIG), the underlying TSIG API doesn't support this
	mode of signing.

	b10-xfrin now installs IXFR differences into the underlying data
	source (if it supports journaling) so that the stored differences
	can be used for subsequent IXFR-out transactions.
	Note: this is a backward incompatibility change for older sqlite3
	database files.  They need to be upgraded to have a "diffs" table.

	module names and all possible item names can be showed in the root

	b10-xfrin would previously initiate incoming transfers upon 
	receiving NOTIFY messages from any address (if the zone was 
	known to b10-xfrin, and using the configured address). It now 
	only starts a transfer if the source address from the NOTIFY 
	packet matches the configured master address and port. This was 
	really already fixed in release bind10-devel-20111014, but there 
	were some deferred cleanups to add.

	libdhcp: DHCP packet library was implemented. Currently it handles
	packet reception, option parsing, option generation and output
	packet building. Generic and specialized classes for several
	DHCPv6 options (IA_NA, IAADDR, address-list) are available. A
	simple code was added that leverages libdhcp. It is a skeleton
	DHCPv6 server. It receives incoming SOLICIT and REQUEST messages
	and responds with proper ADVERTISE and REPLY. Note that since

	LeaseManager is not implemented, server assigns the same

	> config add Xfrout/zone_config[0]/transfer_acl
	> config set Xfrout/zone_config[0]/transfer_acl[0] {"action": "REJECT"}
	The previous global ACL (query_acl) was renamed to transfer_acl,
	which now works as the default ACL.  Note: backward compatibility
	is not provided, so an existing configuration using query_acl
	needs to be updated by hand.
	Note: the per zone configuration framework is a temporary
	workaround.  It will eventually be redesigned as a system wide
	configuration.

	Resolved that the stats module wasn't configurable in bindctl in
	spite of its having configuration items. The configuration part
	was removed from the original spec file "stats.spec" and was
	placed in a new spec file "stats-schema.spec". Because it means
	definitions of statistics items. The command part is still
	there. Thus stats module currently has no its own configuration,
	and the items in "stats-schema.spec" are neither visible nor
	configurable through bindctl. "stats-schema.spec" is shared with

	The host tool is renamed to b10-host. While the utility is
	a work in progress, it is expected to now be shipped with
	tarballs. Its initial goal was to be a host(1) clone,
	rewritten in C++ from scratch and using BIND 10's libdns++.
	It now supports the -a (any), -c class, -d (verbose) switches
	and has improved output.

	Added the HTTP/XML interface (b10-stats-httpd) to the
667 668
	statistics feature in BIND 10. b10-stats-httpd is a standalone
	HTTP server and it requests statistics data to the stats
669
	daemon (b10-stats) and sends it to HTTP clients in XML
670 671
	format. Items of the data collected via b10-stats-httpd
	are almost equivalent to ones which are collected via

	Solved incorrect datetime of "bind10.boot_time" and also
	added a new command "sendstats" for Bob. This command is
	to send statistics data to the stats daemon immediately.
	The solved problem is that statistics data doesn't surely
	reach to the daemon because Bob sent statistics data to
	the daemon while it is starting. So the daemon invokes the
	command for Bob after it starts up. This command is also
	useful for resending statistics data via bindctl manually.

	Add stop interface into dns server, so we can stop each running
942
	server individually. With it, user can reconfigure her running server
943
	with different ip address or port.

	It is possible to start and stop resolver and authoritative
	server without restart of the whole system. Change of the
	configuration (Boss/start_auth and Boss/start_resolver) is
	enough.

	src/lib/dns: revised dnssectime functions so that they don't rely
	on the time_t type (whose size varies on different systems, which
	can lead to subtle bugs like some form of "year 2038 problem").
	Also handled 32-bit wrap around issues more explicitly, with more
	detailed tests.  The function API has been changed, but the effect
	should be minimal because these functions are mostly private.

	complete data source for authoritative DNS servers and b10-auth
	uses it.  It still misses major features, however, including
